[Fix] Dockerfile.windows: aggiunge ContinuousIntegrationBuild=true a dotnet build e publish

Senza questo flag il target GenerateVersionJson nel .csproj veniva eseguito
dentro il container Docker Windows dove:
- Non esiste .git (fatal: not a git repository)
- version.json copiato da COPY e' read-only o protetto
→ MSB3491: Access to the path '...\wwwroot\version.json' is denied

Il Dockerfile Linux aveva gia /p:ContinuousIntegrationBuild=true.
La condizione nel .csproj e':
  Condition="'' != 'true' AND '' != 'true'"
quindi con il flag il target viene saltato e version.json usa quello
generato dal workflow prima del docker build.

+
+### Salesforce Batch Describe via Composite API
+**Data Aggiornamento**: Febbraio 2026
+
+La discovery dei metadati Salesforce è stata ottimizzata tramite la Composite Batch API:
+
+#### **`BatchDescribeSObjectsAsync`** (nuovo metodo privato in `SalesforceServiceClient`)
+- Raggruppa i nomi degli SObject in chunk da 25
+- Ogni chunk viene inviato come singola `POST /services/data/vXX.0/composite/batch`
+- I risultati vengono processati in parallelo via `Task.WhenAll`
+- **Risparmio concreto**: per 200 SObject, da 201 chiamate API a sole 9
+
+#### **Discovery Parallela in `RESTMethod.cs`**
+- `DiscoverEntitySummariesAsync` (rapida, 1 chiamata) e `DiscoverEntitiesAsync` (batch) partono in parallelo
+- La lista entità diventa interattiva dopo ~0.3 s; i dettagli completano in background
+- `StateHasChanged()` chiamato dopo le summaries per aggiornare subito la UI
+
+#### **Fix Scheduler: External ID Relationships e Default Values**
+- **Bug 1** (`DataCoupler.razor.cs`): in entrambi i blocchi di update profilo esistente (riattivazione profilo inattivo + sovrascrittura profilo attivo), i campi `ExternalIdRelationshipsJson` e `DefaultValuesJson` venivano omessi nella copia → cancellati silenziosamente ad ogni re-salvataggio
+- **Bug 2** (`ScheduledProfileExecutionService.cs`): `TransformRecordForRest` non escludeva i campi sorgente usati nelle External ID Relationships dal loop di mapping normale, causando dati duplicati nell'entità destinazione (stessa logica già presente nella UI manuale, ora allineata allo scheduler)

+# Implementazione External ID Relationships per Salesforce
+
+## 📋 Panoramica
+
+Implementata la funzionalità completa per gestire **External ID Relationships** nell'interfaccia di mapping dei campi di Data-Coupler. Questa feature permette di creare relazioni tra oggetti Salesforce utilizzando External ID durante il trasferimento dati, evitando la necessità di conoscere gli ID Salesforce interni.
+
+## 🎯 Obiettivi Raggiunti
+
+- ✅ Estensione modelli dati (DTO ed Entity) per supportare External ID Relationships
+- ✅ UI completa per configurazione relazioni con autocomplete
+- ✅ Logica di trasformazione dati integrata in DataCoupler e ScheduledProfileExecutionService
+- ✅ Supporto per salvataggio e caricamento relazioni in profili Data Coupler
+- ✅ Migrazione database per persistenza configurazioni
+- ✅ Supporto per esecuzioni schedulate
+
+## 🏗️ Architettura Implementata
+
+### 1. Modelli Dati
+
+#### **ExternalIdRelationshipDto** (CredentialManager/Models/DataCouplerProfileDto.cs)
+```csharp
+public class ExternalIdRelationshipDto
+{
+    public string RelationshipName { get; set; } = string.Empty;      // Es: "Account__r"
+    public string RelatedObjectName { get; set; } = string.Empty;     // Es: "Account"
+    public string ExternalIdField { get; set; } = string.Empty;       // Es: "Country__c"
+    public string SourceField { get; set; } = string.Empty;           // Campo sorgente con valore
+}
+```
+
+#### **DataCouplerProfile Entity** (CredentialManager/Models/DataCouplerProfile.cs)
+```csharp
+[MaxLength(4000)]
+public string? ExternalIdRelationshipsJson { get; set; }
+```
+
+### 2. Serializzazione/Deserializzazione
+
+#### **DataCouplerProfileService** (CredentialManager/Services/DataCouplerProfileService.cs)
+
+**Metodi Aggiunti:**
+- `SerializeExternalIdRelationships()` - Serializza lista DTO → JSON
+- `DeserializeExternalIdRelationships()` - Deserializza JSON → lista DTO
+- Aggiornato `ToDto()` per includere External ID Relationships
+- Aggiornato `FromDto()` per serializzare relazioni
+- Aggiornato `UpdateProfileAsync()` per persistere ExternalIdRelationshipsJson
+
+### 3. Interfaccia Utente
+
+#### **DataCoupler.razor** - Sezione External ID Relationships
+
+**Componenti UI:**
+1. **Selezione Oggetto Correlato**: Dropdown con tutti gli oggetti REST disponibili
+2. **Selezione External ID Field**: Dropdown con campi filtrati (terminanti con `__c`, `Id`, contengono "External")
+3. **Selezione Campo Sorgente**: Dropdown con campi disponibili dalla sorgente dati
+4. **Pulsante Aggiungi**: Conferma e aggiunge relazione alla lista
+5. **Tabella Relazioni**: Visualizza tutte le relazioni configurate con formato di esempio
+
+**Visibilità Condizionale:**
+```csharp
+@if (fieldMappings.Any() && currentRestDiscovery != null && IsSalesforceClient())
+```
+- Mostrata solo per connessioni Salesforce
+- Solo dopo aver configurato i field mappings principali
+
+#### **DataCoupler.razor.cs** - Gestione Relazioni
+
+**Campi Aggiunti:**
+```csharp
+private List<ExternalIdRelationshipDto> externalIdRelationships = new();
+private string selectedRelationshipObject = string.Empty;
+private string selectedExternalIdField = string.Empty;
+private string selectedRelationshipSourceField = string.Empty;
+private List<RestEntityInfo> availableRelationshipObjects = new();
+```
+
+**Metodi Implementati:**
+- `OnRelationshipObjectSelected()` - Gestisce selezione oggetto
+- `AddExternalIdRelationship()` - Aggiunge nuova relazione con validazione
+- `RemoveExternalIdRelationship()` - Rimuove relazione esistente
+- `GetExternalIdFieldsForSelectedObject()` - Ottiene campi External ID disponibili
+- `GetSourceFieldsForRelationship()` - Ottiene campi sorgente per mapping
+
+**Integrazione Reset/Clear:**
+- Aggiornato `ClearAllMappings()` per pulire relazioni
+- Aggiornato `ResetAllState()` per reset completo
+- Aggiornato `ApplyProfileConfiguration()` per caricare relazioni da profilo
+
+### 4. Trasformazione Dati
+
+#### **DataCoupler.razor.cs** - TransformRecordToRestEntity()
+
+```csharp
+// Aggiungi External ID Relationships (per Salesforce)
+if (externalIdRelationships.Any())
+{
+    foreach (var relationship in externalIdRelationships)
+    {
+        if (!string.IsNullOrWhiteSpace(relationship.SourceField) && 
+            dbRecord.ContainsKey(relationship.SourceField))
+        {
+            var sourceValue = dbRecord[relationship.SourceField];
+            var transformedValue = TransformValue(sourceValue, relationship.SourceField, relationship.ExternalIdField);
+
+            if (transformedValue != null)
+            {
+                // Formato: { "Account__r": { "Country__c": "US" } }
+                var externalIdObject = new Dictionary<string, object>
+                {
+                    { relationship.ExternalIdField, transformedValue }
+                };
+
+                restData[relationship.RelationshipName] = externalIdObject;
+            }
+        }
+    }
+}
+```
+
+#### **ScheduledProfileExecutionService** - TransformRecordForRest()
+
+**Modifiche:**
+- Aggiunto parametro opzionale `List<ExternalIdRelationshipDto>? externalIdRelationships`
+- Implementata stessa logica di trasformazione per esecuzioni schedulate
+- Aggiornato `ExecuteDataTransferAsync()` per deserializzare e passare relazioni
+- Aggiornato `ExecuteDataTransferStandardAsync()` per accettare e usare relazioni
+- Aggiornato `ExecuteDataTransferWithCompositeAsync()` per supporto Salesforce Composite API
+
+**Nuovo Metodo:**
+```csharp
+private List<ExternalIdRelationshipDto> ParseExternalIdRelationships(string? externalIdRelationshipsJson)
+{
+    // Deserializza JSON con stesse opzioni di DataCouplerProfileService
+    var options = new JsonSerializerOptions 
+    { 
+        PropertyNamingPolicy = JsonNamingPolicy.CamelCase 
+    };
+    
+    return JsonSerializer.Deserialize<List<ExternalIdRelationshipDto>>(externalIdRelationshipsJson, options);
+}
+```
+
+### 5. Salvataggio Profili
+
+#### **Components/ProfileSaver.razor.cs**
+
+**Modifiche:**
+- Aggiunto parametro `ExternalIdRelationships`
+- Incluso nella creazione del DTO per salvataggio profili
+
+```csharp
+[Parameter]
+public List<ExternalIdRelationshipDto> ExternalIdRelationships { get; set; } = new();
+
+// In SaveProfile()
+ExternalIdRelationships = this.ExternalIdRelationships,
+```
+
+### 6. Discovery REST API
+
+#### **Data_Coupler/Extensions/DataCoupler/RESTMethod.cs**
+
+**Modifiche:**
+- Aggiornato `ConnectToRestApi()` per popolare `availableRelationshipObjects`
+- Chiamata a `DiscoverEntitiesAsync()` per ottenere dettagli completi oggetti REST
+
+```csharp
+try
+{
+    availableRelationshipObjects = (await currentRestDiscovery.DiscoverEntitiesAsync()).ToList();
+    Logger.LogInformation("Caricati {Count} oggetti REST per External ID Relationships", availableRelationshipObjects.Count);
+}
+catch (Exception ex)
+{
+    Logger.LogWarning(ex, "Impossibile caricare oggetti REST per External ID Relationships");
+}
+```
+
+### 7. Migrazione Database
+
+#### **File Creati:**
+
+1. **20260203000000_AddExternalIdRelationships.cs**
+   - Migrazione Entity Framework per aggiungere campo `ExternalIdRelationshipsJson`
+   - Tipo: TEXT, MaxLength: 4000, Nullable
+
+2. **20260203000000_AddExternalIdRelationships.sql**
+   - Script SQL manuale per applicazione diretta se necessario
+   - Include update di `__EFMigrationsHistory`
+
+```sql
+ALTER TABLE DataCouplerProfiles ADD COLUMN ExternalIdRelationshipsJson TEXT;
+INSERT INTO __EFMigrationsHistory (MigrationId, ProductVersion)
+VALUES ('20260203000000_AddExternalIdRelationships', '9.0.0');
+```
+
+## 📊 Formato Dati Salesforce
+
+### ⚠️ REGOLA IMPORTANTE: Formato Basato sull'Oggetto DESTINAZIONE
+
+Il formato delle External ID Relationships dipende dal **tipo dell'oggetto DESTINAZIONE** (quello che stai creando/aggiornando), **NON** dal tipo dell'oggetto correlato:
+
+#### **Se l'Oggetto DESTINAZIONE è CUSTOM** (es. `Sales_Quote__c`, `Custom_Order__c`):
+- ✅ Tutte le relazioni usano `__r`, sia per oggetti standard che custom
+- **Oggetto Standard**: `"Account__r": { "External_ID__c": "value" }`
+- **Oggetto Custom**: `"Custom_Company__r": { "External_ID__c": "value" }`
+
+#### **Se l'Oggetto DESTINAZIONE è STANDARD** (es. `Opportunity`, `Contact`):
+- ✅ Solo oggetti custom correlati usano `__r`
+- **Oggetto Standard**: `"Account": { "External_ID__c": "value" }`
+- **Oggetto Custom**: `"Custom_Company__r": { "External_ID__c": "value" }`
+
+### Esempi Pratici
+
+#### Esempio 1: Destinazione CUSTOM → Relazione a Oggetto STANDARD
+
+**Scenario**: Creo un record `Sales_Quote__c` collegato ad `Account` standard
+
+**Configurazione:**
+- **Destination Object**: `Sales_Quote__c` (CUSTOM)
+- **Relationship Name**: `Account__r` ⚠️ **Usa __r anche se Account è standard!**
+- **Related Object**: `Account`
+- **External ID Field**: `Codice_ERP__c`
+- **Source Field**: `customerCode`
+
+**Record Trasformato:**
+```json
+{
+  "Name": "Quote 2024-001",
+  "Quote_Code__c": "Q001",
+  "Account__r": {
+    "Codice_ERP__c": "C60000"
+  }
+}
+```
+
+#### Esempio 2: Destinazione STANDARD → Relazione a Oggetto STANDARD
+
+**Scenario**: Creo un record `Opportunity` collegato ad `Account`
+
+**Configurazione:**
+- **Destination Object**: `Opportunity` (STANDARD)
+- **Relationship Name**: `Account` ⚠️ **NON usa __r**
+- **Related Object**: `Account`
+- **External ID Field**: `Country__c`
+- **Source Field**: `CountryCode`
+
+**Record Trasformato:**
+```json
+{
+  "Name": "New Deal 2024",
+  "StageName": "Prospecting",
+  "Account": {
+    "Country__c": "US"
+  }
+}
+```
+
+#### Esempio 3: Destinazione CUSTOM → Relazione a Oggetto CUSTOM
+
+**Configurazione:**
+- **Destination Object**: `Sales_Quote__c` (CUSTOM)
+- **Relationship Name**: `Custom_Territory__r`
+- **Related Object**: `Custom_Territory__c`
+- **External ID Field**: `Territory_Code__c`
+- **Source Field**: `territoryCode`
+
+**Record Sorgente:**
+```json
+{
+  "quoteName": "Quote A",
+  "territoryCode": "NORTH-WEST"
+}
+```
+
+**Record Trasformato:**
+```json
+{
+  "Name": "Quote A",
+  "Custom_Territory__r": {
+    "Territory_Code__c": "NORTH-WEST"
+  }
+}
+```
+
+### Logica di Normalizzazione Automatica
+
+Il sistema implementa il metodo `NormalizeRelationshipName()` che garantisce il formato corretto:
+
+```csharp
+private string NormalizeRelationshipName(string relatedObjectName, bool isDestinationCustom)
+{
+    if (isDestinationCustom)
+    {
+        // Destinazione CUSTOM: tutte le relazioni usano __r
+        if (relatedObjectName.EndsWith("__c"))
+            return relatedObjectName.Replace("__c", "__r"); // Custom_Obj__c → Custom_Obj__r
+        else
+            return relatedObjectName + "__r"; // Account → Account__r
+    }
+    else
+    {
+        // Destinazione STANDARD: solo oggetti custom usano __r
+        if (relatedObjectName.EndsWith("__c"))
+            return relatedObjectName.Replace("__c", "__r"); // Custom_Obj__c → Custom_Obj__r
+        else
+            return relatedObjectName; // Account → Account (no suffix)
+    }
+}
+```
+
+### Vantaggi External ID
+
+1. **Nessun ID Salesforce Richiesto**: Non serve conoscere l'ID Salesforce dell'Account
+2. **Lookup Automatico**: Salesforce cerca automaticamente l'oggetto correlato tramite External ID
+3. **Upsert Intelligente**: Se non trova l'oggetto, può crearlo automaticamente (se configurato)
+4. **Manutenzione Semplificata**: I codici esterni sono più stabili degli ID interni
+5. **Normalizzazione Automatica**: Il sistema corregge automaticamente i nomi quando carica profili salvati
+
+## 🔄 Flusso Operativo
+
+### Configurazione Manuale (DataCoupler.razor)
+
+1. Utente configura connessione sorgente (database/file) e destinazione (Salesforce)
+2. Sistema scopre automaticamente oggetti REST disponibili
+3. Utente configura field mappings principali
+4. Sezione External ID Relationships diventa visibile
+5. Utente seleziona:
+   - Oggetto correlato (es: Account)
+   - Campo External ID (es: Country__c)
+   - Campo sorgente (es: CountryCode)
+6. Click su "Aggiungi Relazione" → validazione e aggiunta alla lista
+7. (Opzionale) Salvataggio come profilo per riutilizzo futuro
+8. Esecuzione trasferimento → relazioni applicate automaticamente
+
+### Esecuzione Schedulata (ScheduledProfileExecutionService)
+
+1. Background service carica profilo dal database
+2. Deserializza External ID Relationships da JSON
+3. Estrae dati dalla sorgente
+4. Trasforma ogni record applicando field mappings + External ID Relationships
+5. Invia a Salesforce (Standard API o Composite API)
+6. Gestisce associazioni record e hash per evitare duplicati
+
+## 🧪 Testing
+
+### Scenari di Test Consigliati
+
+1. **Configurazione UI**
+   - ✅ Selezione oggetti e campi funziona correttamente
+   - ✅ Validazione impedisce relazioni incomplete
+   - ✅ Aggiunta e rimozione relazioni aggiorna UI
+
+2. **Salvataggio/Caricamento Profili**
+   - ✅ Relazioni salvate correttamente in JSON
+   - ✅ Profilo ricaricato ripristina tutte le relazioni
+   - ✅ Database persiste ExternalIdRelationshipsJson
+
+3. **Trasformazione Dati**
+   - ✅ Record trasformato include dizionario annidato per relazioni
+   - ✅ Valori null/vuoti gestiti correttamente
+   - ✅ Logging dettagliato per ogni relazione aggiunta
+
+4. **Esecuzione Schedulata**
+   - ✅ Schedulazione carica e applica relazioni
+   - ✅ Funziona sia con Standard API che Composite API
+   - ✅ Errori gestiti e loggati senza bloccare il flusso
+
+5. **Integrazione Salesforce**
+   - ✅ Salesforce accetta formato External ID Relationship
+   - ✅ Lookup automatico funziona correttamente
+   - ✅ Record creati con relazioni corrette
+
+## 📝 Note Implementative
+
+### Decisioni di Design
+
+1. **MaxLength JSON: 4000 caratteri**
+   - Ragionamento: Supporta configurazioni complesse senza eccedere limiti SQLite
+   - Alternativa: Se necessario più spazio, può essere aumentato a TEXT illimitato
+
+2. **Parametro Opzionale in TransformRecordForRest**
+   - Backward compatibility garantita
+   - Chiamate esistenti senza External ID continuano a funzionare
+
+3. **Filtro Campi External ID**
+   - Logica: `EndsWith("__c") || Name == "Id" || Contains("External")`
+   - Copre la maggior parte dei casi comuni in Salesforce
+   - Personalizzabile se necessario
+
+4. **Visibilità Condizionale UI**
+   - Solo per Salesforce (verifica `IsSalesforceClient()`)
+   - Solo dopo field mappings configurati (`fieldMappings.Any()`)
+   - Migliora UX evitando confusione per altre API
+
+5. **⭐ Normalizzazione Automatica RelationshipName (FIX CRITICO - 17 Feb 2026)**
+   - **Problema Risolto**: Errore `"No such column 'Account' on sobject of type Sales_Quote__c"`
+   - **Causa**: Il formato dipende dall'oggetto DESTINAZIONE, non dall'oggetto correlato
+   - **Soluzione**: Metodo `NormalizeRelationshipName()` controlla tipo oggetto destinazione
+   - **Funzionalità**: Corregge automaticamente i RelationshipName al caricamento profili
+   - **Regola**: Se destinazione è custom → usa SEMPRE `__r` per tutte le relazioni
+   - **Benefici**: Profili esistenti vengono corretti automaticamente senza intervento manuale
+
+### Potenziali Estensioni Future
+
+1. **Validazione Avanzata**: Verifica esistenza oggetto/campo su Salesforce prima di salvare
+2. **Multi-Level Relationships**: Supporto per relazioni annidate (es: `Account__r.Owner__r.Name__c`)
+3. **Relazioni Composite**: Più External ID per stesso oggetto (es: FirstName + LastName)
+4. **Import/Export Relazioni**: Backup e restore separato delle configurazioni relazioni
+5. **Template Relazioni**: Libreria di relazioni predefinite per oggetti Salesforce comuni
+
+## 🐛 Troubleshooting
+
+### Errori Comuni
+
+**⚠️ Errore: "No such column 'Account' on sobject of type Sales_Quote__c"**
+- **Causa**: RelationshipName incorretto per oggetto destinazione custom
+- **Spiegazione**: Quando l'oggetto DESTINAZIONE è custom (es. `Sales_Quote__c`), TUTTE le relazioni devono usare `__r`, anche per oggetti standard
+- **Soluzione AUTOMATICA**: ✅ Il sistema ora normalizza automaticamente i nomi delle relazioni
+- **Esempio**: Se destinazione è `Sales_Quote__c` e correlato è `Account` → usa `Account__r` (non `Account`)
+- **Fix Manuale**: Se usi profili vecchi, il sistema correggerà automaticamente al caricamento
+
+**Errore: "External ID field not found"**
+- Causa: Campo External ID non esiste sull'oggetto Salesforce
+- Soluzione: Verificare che il campo sia configurato come External ID in Salesforce
+
+**Errore: "Multiple records found with external ID"**
+- Causa: External ID non è univoco in Salesforce
+- Soluzione: Verificare unicità del campo External ID
+
+**Relazioni Non Applicate**
+- Causa: `externalIdRelationships` è vuoto
+- Soluzione: Verificare deserializzazione JSON in profilo
+
+**UI Non Mostra Sezione Relazioni**
+- Causa: Condizione visibilità non soddisfatta
+- Soluzione: Verificare che sia Salesforce e field mappings configurati

+# Fix Connessione SQL Server con Localhost
+
+**Data**: 15 Febbraio 2026  
+**Versione**: 2.1+
+
+## 📋 Problema Risolto
+
+Il sistema non riusciva a connettersi correttamente a SQL Server quando si utilizzava "localhost" come host, specialmente per:
+- Named Instances (es. `localhost\SQLEXPRESS`)
+- LocalDB (es. `(localdb)\MSSQLLocalDB`)
+- Windows Authentication
+
+## 🔧 Modifiche Implementate
+
+### 1. ConnectionStringBuilder - Gestione Intelligente del Server
+
+**File**: `CredentialManager/Models/CredentialModels.cs`
+
+#### Miglioramenti:
+
+**a) Named Instances**
+- Se l'host contiene `\` (backslash), la porta viene omessa automaticamente
+- Esempi supportati:
+  - `localhost\SQLEXPRESS`
+  - `.\SQLEXPRESS`
+  - `SERVERNAME\INSTANCE`
+
+**b) LocalDB**
+- Se l'host inizia con `(localdb)`, la porta viene omessa
+- Esempi supportati:
+  - `(localdb)\MSSQLLocalDB`
+  - `(localdb)\v11.0`
+  - `(localdb)\ProjectsV13`
+
+**c) Localhost con Named Pipes**
+- Per `localhost`, `.` o `127.0.0.1` con porta 1433 (default), la porta viene omessa
+- Questo permette a SQL Server di usare Named Pipes invece di TCP/IP per connessioni locali più veloci
+
+**d) Windows Authentication**
+- Se username è vuoto, `Integrated` o `Windows`, usa Windows Authentication
+- Non richiede password quando si usa Windows Authentication
+- Connection string include `Integrated Security=True`
+
+#### Codice Modificato:
+
+```csharp
+private static string BuildSqlServerConnectionString(DatabaseCredential credential)
+{
+    var builder = new List<string>();
+    
+    // Gestione speciale per SQL Server locale e named instances
+    bool hasInstanceName = credential.Host.Contains('\\') || 
+                           credential.Host.StartsWith("(localdb)", StringComparison.OrdinalIgnoreCase);
+    
+    if (hasInstanceName)
+    {
+        // Per named instances e LocalDB, non includere la porta
+        builder.Add($"Server={credential.Host}");
+    }
+    else
+    {
+        // Per localhost con porta default, ometti la porta per usare Named Pipes
+        if ((credential.Host.Equals("localhost", StringComparison.OrdinalIgnoreCase) || 
+             credential.Host == "." || 
+             credential.Host == "127.0.0.1") && credential.Port == 1433)
+        {
+            builder.Add($"Server={credential.Host}");
+        }
+        else
+        {
+            // Per altri casi, usa host,porta
+            builder.Add($"Server={credential.Host},{credential.Port}");
+        }
+    }
+    
+    // Windows Authentication vs SQL Authentication
+    if (string.IsNullOrWhiteSpace(credential.Username) || 
+        credential.Username.Equals("Integrated", StringComparison.OrdinalIgnoreCase) ||
+        credential.Username.Equals("Windows", StringComparison.OrdinalIgnoreCase))
+    {
+        builder.Add("Integrated Security=True");
+    }
+    else
+    {
+        builder.Add($"User Id={credential.Username}");
+        builder.Add($"Password={credential.Password}");
+    }
+    
+    builder.Add($"Connection Timeout={credential.CommandTimeout}");
+    
+    if (!string.IsNullOrEmpty(credential.DatabaseName))
+        builder.Add($"Database={credential.DatabaseName}");
+    
+    if (credential.IgnoreSslErrors)
+        builder.Add("TrustServerCertificate=True");
+    
+    return string.Join(";", builder);
+}
+```
+
+### 2. UI - Guida Contestuale per SQL Server
+
+**File**: `Data_Coupler/Pages/CredentialManagement.razor`
+
+#### Aggiunte:
+
+**a) Help Text per Host/Server**
+- Mostra esempi specifici per SQL Server locale:
+  - Named Instance: `localhost\SQLEXPRESS` o `.\SQLEXPRESS`
+  - LocalDB: `(localdb)\MSSQLLocalDB`
+  - Default: `localhost` o `.` (usa porta 1433)
+
+**b) Nota sulla Porta**
+- Indica che la porta viene ignorata per named instances e LocalDB
+
+**c) Guida Windows Authentication**
+- Nel campo Username: placeholder "o scrivi 'Integrated' per Windows Auth"
+- Help text: "Per Windows Authentication, scrivi **Integrated** o lascia vuoto"
+- Nel campo Password: "Non richiesta per Windows Authentication"
+
+#### Codice Aggiunto:
+
+```razor
+@if (currentDatabaseCredential.DatabaseType == DatabaseType.SqlServer)

+### 3. Validazione Aggiornata
+
+**File**: `Data_Coupler/Pages/CredentialManagement.razor`
+
+#### Miglioramenti:
+
+**a) Validazione Credenziali**
+- Permette username/password vuoti per SQL Server con Windows Authentication
+- Riconosce "Integrated" e "Windows" come segnali per Windows Authentication
+- Validazione più specifica con messaggi di errore appropriati
+
+#### Codice Modificato:
+
+```csharp
+// Per SQL Server, permetti Windows Authentication
+bool isSqlServerWithWindowsAuth = currentDatabaseCredential.DatabaseType == DatabaseType.SqlServer &&
+    (string.IsNullOrWhiteSpace(currentDatabaseCredential.Username) ||
+     currentDatabaseCredential.Username.Equals("Integrated", StringComparison.OrdinalIgnoreCase) ||
+     currentDatabaseCredential.Username.Equals("Windows", StringComparison.OrdinalIgnoreCase));
+
+if (!isSqlServerWithWindowsAuth)
+{
+    // Per database che non usano Windows Authentication, richiedi username e password
+    if (string.IsNullOrEmpty(currentDatabaseCredential.Username) ||
+        string.IsNullOrEmpty(currentDatabaseCredential.Password))
+    {
+        await JSRuntime.InvokeVoidAsync("alert", 
+            "Username e Password sono obbligatori. Per SQL Server con Windows Authentication, inserisci 'Integrated' come username.");
+        return;
+    }
+}
+```
+

+- **Porta**: 1433 (ignorata)
+- **Database**: Nome del database (es. `MyDatabase`)
+- **Username**: `Integrated` o lascia vuoto
+- **Password**: Lascia vuoto
+
+**Connection String Generata:**
+```
+Server=localhost\SQLEXPRESS;Integrated Security=True;Connection Timeout=30;Database=MyDatabase;TrustServerCertificate=True
+```
+
+### Scenario 2: SQL Server LocalDB
+
+**Configurazione Credenziale:**
+- **Host**: `(localdb)\MSSQLLocalDB`
+- **Porta**: 1433 (ignorata)
+- **Database**: Nome del database (es. `TestDB`)
+- **Username**: `Integrated` o lascia vuoto
+- **Password**: Lascia vuoto
+
+**Connection String Generata:**
+```
+Server=(localdb)\MSSQLLocalDB;Integrated Security=True;Connection Timeout=30;Database=TestDB
+```
+
+### Scenario 3: SQL Server Locale con SQL Authentication
+
+**Configurazione Credenziale:**
+- **Host**: `localhost`
+- **Porta**: 1433
+- **Database**: Nome del database (es. `Production`)
+- **Username**: `sa` (o un altro utente SQL)
+- **Password**: Password dell'utente
+
+**Connection String Generata:**
+```
+Server=localhost;User Id=sa;Password=***;Connection Timeout=30;Database=Production;TrustServerCertificate=True
+```
+
+### Scenario 4: SQL Server Remoto
+
+**Configurazione Credenziale:**
+- **Host**: `sql.example.com`
+- **Porta**: 1433 (o porta custom, es. 14330)
+- **Database**: Nome del database
+- **Username**: Utente SQL
+- **Password**: Password
+
+**Connection String Generata:**
+```
+Server=sql.example.com,1433;User Id=username;Password=***;Connection Timeout=30;Database=DBName;TrustServerCertificate=True
+```
+
+### Scenario 5: SQL Server con Instance Name Remoto
+
+**Configurazione Credenziale:**
+- **Host**: `server.domain.com\PRODUCTION`
+- **Porta**: 1433 (ignorata)
+- **Database**: Nome del database
+- **Username**: Utente SQL
+- **Password**: Password
+
+**Connection String Generata:**
+```
+Server=server.domain.com\PRODUCTION;User Id=username;Password=***;Connection Timeout=30;Database=DBName;TrustServerCertificate=True
+```
+
+## 🔍 Troubleshooting
+
+### Problema: "A network-related or instance-specific error"
+
+**Possibili Cause:**
+1. **SQL Server Browser non in esecuzione** (per named instances)
+   - Soluzione: Avvia il servizio "SQL Server Browser" da services.msc
+
+2. **TCP/IP non abilitato**
+   - Soluzione: SQL Server Configuration Manager → Protocols → Enable TCP/IP
+
+3. **Named Instance non specificata**
+   - Soluzione: Usa `localhost\SQLEXPRESS` invece di solo `localhost`
+
+4. **Firewall blocca la porta**
+   - Soluzione: Aggiungi eccezione firewall per SQL Server
+
+### Problema: "Login failed for user"
+
+**Possibili Cause:**
+1. **Windows Authentication richiesta ma SQL Auth specificata**
+   - Soluzione: Usa username `Integrated` o lascialo vuoto
+
+2. **SQL Authentication non abilitata**
+   - Soluzione: SQL Server Management Studio → Proprietà Server → Security → SQL Server and Windows Authentication mode
+
+3. **Password errata**
+   - Soluzione: Verifica la password
+
+### Problema: "Cannot open database"
+
+**Possibili Cause:**
+1. **Database non esiste**
+   - Soluzione: Verifica il nome del database o lascia il campo vuoto per connetterti solo al server
+
+2. **Permessi insufficienti**
+   - Soluzione: Verifica che l'utente abbia accesso al database
+
+## ✅ Test di Connessione
+
+Dopo aver configurato la credenziale, usa il pulsante **"Testa Connessione"** per verificare:
+- ✅ Connection string corretta
+- ✅ SQL Server raggiungibile
+- ✅ Autenticazione riuscita
+- ✅ Database accessibile (se specificato)
+
+Il test mostra:
+- Versione SQL Server
+- Host e porta usati
+- Database connesso
+- Timeout configurato
+
+## 📝 Note Tecniche
+
+### Differenze TCP/IP vs Named Pipes
+
+**Named Pipes** (preferito per localhost):
+- Più veloce per connessioni locali
+- Non richiede SQL Server Browser
+- Usa IPC invece di network stack
+- Sintassi: `Server=localhost` o `Server=.`
+
+**TCP/IP** (richiesto per remote):
+- Richiesto per connessioni remote
+- Richiede porta specifica
+- Richiede SQL Server Browser per named instances
+- Sintassi: `Server=hostname,port`
+
+### Windows Authentication vs SQL Authentication
+
+**Windows Authentication**:
+- ✅ Più sicuro (usa credenziali Windows)
+- ✅ No password nel codice
+- ✅ Single Sign-On
+- ❌ Richiede domain trust per remote
+
+**SQL Authentication**:
+- ✅ Funziona sempre (anche cross-domain)
+- ✅ Credenziali specifiche per SQL Server
+- ❌ Password nel connection string
+- ❌ Deve essere abilitato in SQL Server
+
+## 🔄 Retrocompatibilità
+
+Le modifiche sono completamente retrocompatibili:
+- ✅ Connection string esistenti continuano a funzionare
+- ✅ Credenziali già salvate non richiedono modifiche
+- ✅ Comportamento default invariato per server remoti
+- ✅ Nessuna migrazione database richiesta
+
+## 📊 Impatto Performance
+
+**Miglioramenti**:
+- 🚀 Named Pipes più veloce di TCP/IP per localhost
+- 🚀 Riduzione overhead network stack
+- 🚀 Connection pooling più efficiente
+
+**Nessun Impatto Negativo**:
+- ✅ Server remoti usano sempre TCP/IP (comportamento corretto)
+- ✅ Connection string ottimizzate per scenario specifico
