# Documentation: DTS.Common.DBSyncService

## 1. Purpose

This module provides configuration and assembly metadata for the DTS Database Synchronization Service, a Windows service component. It defines application-level settings that control service behavior, including monitoring enablement, execution interval, and service identification. The module serves as the configuration layer for a database synchronization service that appears to operate on a timed interval basis.

---

## 2. Public Interface

### `DTS.Common.DBSyncService.Properties.Settings`

An internal sealed partial class that provides strongly-typed access to application configuration settings. Inherits from `global::System.Configuration.ApplicationSettingsBase`.

#### Static Property: `Default`

```csharp
public static Settings Default { get; }
```

Returns the singleton instance of the `Settings` class, synchronized for thread-safe access.

#### Property: `Monitoring`

```csharp
public bool Monitoring { get; }
```

Application-scoped setting indicating whether monitoring is enabled. Default value: `False`.

#### Property: `Interval`

```csharp
public int Interval { get; }
```

Application-scoped setting defining the execution interval. Default value: `60000` (presumed milliseconds, equating to 60 seconds).

#### Property: `ServiceName`

```csharp
public string ServiceName { get; }
```

Application-scoped setting for the service display name. Default value: `"DTS DB Sync Service"`.

#### Property: `Service`

```csharp
public string Service { get; }
```

Application-scoped setting for the service identifier. Default value: `"DB Sync Service"`.

## 3. Invariants

- **Singleton Pattern**: The `Settings` class maintains exactly one synchronized instance accessible via `Settings.Default`.
- **Application-Scoped Settings**: All four settings (`Monitoring`, `Interval`, `ServiceName`, `Service`) are application-scoped, meaning they are read-only at runtime and must be configured at the application level (e.g., via `app.config` or `web.config`).
- **COM Visibility**: All types in this assembly are not visible to COM components (`ComVisible(false)`).
- **Assembly Identity**: The assembly GUID `5f8e95eb-e89c-4fdc-9bde-3e78dd56ad6f` uniquely identifies this assembly's type library if exposed to COM.

## 4. Dependencies

### This module depends on:
- `System.Reflection` - For assembly metadata attributes
- `System.Runtime.CompilerServices` - For compiler-generated attributes
- `System.Runtime.InteropServices` - For COM interop attributes (`ComVisible`, `Guid`)
- `System.Configuration` - For `ApplicationSettingsBase` base class and configuration attributes
- `System.Diagnostics` - For `DebuggerNonUserCodeAttribute`

### What depends on this module:
- **Cannot be determined from source alone.** The consuming components would be
