# Documentation: IManageUsersView & IManageUsersViewModel Interfaces

## 1. Purpose

This module defines two marker interfaces, `IManageUsersView` and `IManageUsersViewModel`, which serve as type identifiers for the Manage Users feature within an MVVM (Model-View-ViewModel) architecture. These interfaces extend base view and view model contracts from the `DTS.Common.Base` namespace, enabling type-safe association between views and view models in the user management subsystem without defining any additional members.

## 2. Public Interface

### `IManageUsersView`
- **Namespace:** `DTS.Common.Interface`
- **Inheritance:** `IBaseView`
- **Signature:**
  ```csharp
  public interface IManageUsersView : IBaseView
  ```
- **Behavior:** Empty marker interface. Inherits from `IBaseView` but declares no additional members. Used to identify views specifically related to user management.

### `IManageUsersViewModel`
- **Namespace:** `DTS.Common.Interface`
- **Inheritance:** `IBaseViewModel`
- **Signature:**
  ```csharp
  public interface IManageUsersViewModel : IBaseViewModel
  ```
- **Behavior:** Empty marker interface. Inherits from `IBaseViewModel` but declares no additional members. Used to identify view models specifically related to user management.

## 3. Invariants

- Both interfaces are empty; they define no members beyond those inherited from their respective base interfaces.
- `IManageUsersView` must always be assignable to `IBaseView`.
- `IManageUsersViewModel` must always be assignable to `IBaseViewModel`.
- The behavior and invariants of `IBaseView` and `IBaseViewModel` are not defined in the provided source; their contracts are inherited but unspecified here.

## 4. Dependencies

### This module depends on:
- `DTS.Common.Base` — provides `IBaseView` and `IBaseViewModel` base interfaces

### What depends on this module:
- **Unclear from source alone.** Consumers would typically include concrete view and view model implementations for the Manage Users feature, but these are not present in the provided files.

## 5. Gotchas

- **Empty marker interfaces:** Both interfaces declare no members. This is either intentional (for type discrimination/registration purposes) or represents incomplete implementation. The source alone cannot distinguish between these cases.
- **Base interface contracts unknown:** The actual responsibilities and members inherited from `IBaseView` and `IBaseViewModel` are not visible in the provided source. Developers must consult `DTS.Common.Base` to understand the full interface contract.
- **Naming convention:** The interfaces follow a naming pattern suggesting MVVM pairing, but no compile-time enforcement links a specific view to its corresponding view model.
