## Instructions & Workflow

### Standard Procedure

1. **Context Gathering**
   - Review [CLAUDE.md](../../CLAUDE.md) for c-entron.NET conventions
   - Use Serena MCP to understand feature implementation
   - Identify layers involved (Database, BL, WebServiceBL, Logic, UI)
   - Check connection type support (SqlServer, WebServices, or both)
   - Review existing documentation for style consistency

2. **Structure Planning**
   - Determine documentation type (module docs, pattern guide, API reference, etc.)
   - Plan structure appropriate for c-entron.NET context
   - Identify code examples needed
   - Plan architecture diagrams if needed

3. **Content Creation**
   - Write clear, concise c-entron.NET-specific documentation
   - Include working code examples following c-entron.NET conventions
   - Add layer responsibilities and data flow explanations
   - Document connection type differences (SqlServer vs WebServices)
   - Include localization key conventions
   - Add troubleshooting sections for common issues

4. **Code Example Validation**
   - Ensure examples follow Result<T> pattern
   - Verify ILogic interface usage
   - Check ClassContainer DI patterns
   - Validate soft delete filters
   - Confirm German/English localization
   - Test code examples if possible

5. **Review and Polish**

        {
            var entities = _session.Query<[Entity]>()
                .Where(x => !x.IsDeleted) // ALWAYS filter soft delete
                .Fetch(x => x.RelatedEntity) // Eager loading
                .ToList();
            return Result.Success(entities);

        if (!result.IsSuccess)
            return Result.Error<[Entity]DTO>(result.Message);

        // Entity → DTO conversion
        var dto = ObjectMapper.Map<[Entity]DTO>(result.Value);
        return Result.Success(dto);
    }
}
```

### REST Endpoint
**ICentronRestService.cs**:

    Result Delete[Entity](int id);
}
```

### BL[Entity]Logic.cs (SqlServer)

{
    // REST API client for WebServices connection type
    private readonly ICentronRestService _restService;
}
```

## UI Layer

### WPF Module (Desktop)

**[Module]ModuleController.cs**:
```csharp
public class [Module]ModuleController : ICentronAppModuleController
{
    public string Caption => LocalizedStrings.[Module]_Caption;
    public UserControl CreateModule() => new [Module]ModuleView();
}
```

**[Module]ModuleView.xaml**:
```xml
<UserControl x:Class="..."
             xmlns:dx="http://schemas.devexpress.com/winfx/2008/xaml/core">
    <dx:DXTabControl>
        <!-- DevExpress controls -->
        <dx:GridControl ItemsSource="{Binding Entities}">
            <!-- Grid columns -->
        </dx:GridControl>
    </dx:DXTabControl>
</UserControl>
```

**[Module]ModuleViewModel.cs**:
```csharp
public class [Module]ModuleViewModel : BindableBase, IDisposable
{
    private readonly I[Entity]Logic _logic;

    public [Module]ModuleViewModel()
    {
        _logic = ClassContainer.Instance.GetInstance<I[Entity]Logic>();
        LoadData();
    }

    private async void LoadData()
    {
        var result = await _logic.GetAll[Entity]s();
        if (result.IsSuccess)
        {
            Entities = result.Value;
        }
        else
        {
            MessageBoxHelper.ShowError(result.Message);
        }
    }

    public void Dispose()
    {
        ClassContainer.Instance.ReleaseInstance(_logic);
    }
}
```

### Blazor Module (Web Portal)

**[Entity].razor**:
```razor
@page "/[entity]"
@inject I[Entity]Logic Logic

<DxGrid Data="@Entities">
    <!-- DevExpress Blazor grid columns -->
</DxGrid>

@code {
    private List<[Entity]> Entities { get; set; }

    protected override async Task OnInitializedAsync()
    {
        var result = await Logic.GetAll[Entity]s();
        Entities = result.IsSuccess ? result.Value : new List<[Entity]>();
    }
}
```

## Localization

### LocalizedStrings.resx (German - Primary)
```
[Module]_Caption = [German Caption]
[Module]_Save_Button = Speichern
[Module]_Delete_Button = Löschen
[Module]_ErrorMessage = Fehler beim Laden
```

### LocalizedStrings.en.resx (English - Secondary)
```
[Module]_Caption = [English Caption]
[Module]_Save_Button = Save
[Module]_Delete_Button = Delete
[Module]_ErrorMessage = Error loading data
```

### Usage
**Code**:
```csharp
MessageBoxHelper.ShowInfo(LocalizedStrings.[Module]_SaveSuccess);
```

**XAML**:
```xml
<Button Content="{x:Static properties:LocalizedStrings.[Module]_Save_Button}"/>
```

## User Rights

### Registration
**UserRightsConst.cs**:
```csharp
public const int [MODULE_RIGHT] = [NextAvailableID];
```

**ScriptMethod###.cs**:
```csharp
ScriptHelpers.AddRightIfNotExists(
    UserRightsConst.[MODULE_RIGHT],
    UserRightsConst.[PARENT_RIGHT],
    "[German Name]",
    "[German Description]"
);
```

### Checking Rights
```csharp
if (!UserHelper.HasRight(UserRightsConst.[MODULE_RIGHT]))
{
    return Result.Error("Insufficient permissions");
}
```

## Usage Examples

### Creating New Entity
```csharp
var logic = ClassContainer.Instance.GetInstance<I[Entity]Logic>();
try
{
    var entity = new [Entity]
    {
        // Set properties
    };

    var result = await logic.Save[Entity](entity);
    if (result.IsSuccess)
    {
        MessageBoxHelper.ShowInfo(LocalizedStrings.[Module]_SaveSuccess);
    }
    else
    {
        MessageBoxHelper.ShowError(result.Message);
    }
}
finally
{
    ClassContainer.Instance.ReleaseInstance(logic);
}
```

### Querying with Filters
```csharp
var entities = session.Query<[Entity]>()
    .Where(x => !x.IsDeleted) // REQUIRED: Soft delete filter
    .Where(x => x.[Property] == value)
    .Fetch(x => x.RelatedEntity) // Eager loading
    .ToList();
```

## Common Patterns

### Result<T> Pattern
✅ **ALWAYS** use Result<T> for operations that can fail:
```csharp
public Result<T> Method()
{
    try
    {
        // Business logic
        return Result.Success(value);
    }
    catch (Exception ex)
    {
        return Result.Error<T>(ex);
    }
}
```

### ClassContainer Disposal
✅ **ALWAYS** release ClassContainer instances:
```csharp
// Single use
var result = await ClassContainer.Instance
    .WithInstance((ILogic logic) => logic.Method())
    .ThrowIfError();

// Multiple uses - implement IDisposable
public void Dispose()
{
    ClassContainer.Instance.ReleaseInstance(_logic);
}
```

### Soft Delete
✅ **ALWAYS** filter deleted records:
```csharp
.Where(x => !x.IsDeleted)
```

## Troubleshooting

### Issue: "Instance not found in ClassContainer"
**Cause**: ILogic interface not registered or already released
**Solution**: Check registration in ClassContainer configuration

### Issue: Lazy loading exception
**Cause**: NHibernate session closed before accessing navigation property
**Solution**: Use `.Fetch()` for eager loading

### Issue: Deleted records appearing
**Cause**: Missing soft delete filter
**Solution**: Add `.Where(x => !x.IsDeleted)` to all queries

### Issue: Wrong language displayed
**Cause**: Missing translation or wrong locale
**Solution**: Check both LocalizedStrings.resx and LocalizedStrings.en.resx

- Don't forget to document soft delete filters
- Don't omit connection type considerations
- Don't skip localization documentation
- Don't forget UTF-8 with BOM encoding notes

## Examples

### Example 1: Module Documentation

**User Request:**
```
Document the CustomerModule implementation
```

**Agent Process:**
1. Review CLAUDE.md for c-entron.NET conventions
2. Use Serena MCP to understand CustomerModule structure
3. Identify all layers: Customer table, Customer entity, CustomerBL, CustomerWebServiceBL, ICustomerLogic, CustomerModuleView
4. Document database schema with I3D, tracking columns
5. Show Result<T> pattern in CustomerBL methods
6. Document ClassContainer usage in CustomerModuleViewModel
7. Include localization keys and German/English translations
8. Add troubleshooting section for common issues
9. Create architecture diagram showing layer flow

**Expected Output:**
Complete module documentation with all layers, code examples, localization, troubleshooting.

---

### Example 2: Pattern Documentation

**User Request:**
```
Document the Result<T> pattern for new developers
```

**Agent Process:**
1. Review Result<T> usage across c-entron.NET codebase
2. Explain purpose: consistent error handling across layers
3. Show BL layer implementation with try-catch returning Result.Error()
4. Show UI layer consumption with .IsSuccess checks and .ThrowIfError()
5. Document WebServiceBL DTO conversion with Result<T>
6. Include common mistakes (not checking .IsSuccess)
7. Add best practices (always use Result<T> for operations that can fail)
8. Create examples showing error propagation through layers

**Expected Output:**
Pattern documentation with purpose, implementation guide, examples, common mistakes, best practices.
