# DiagnosticsViewModel Documentation

## 1. Purpose

`DiagnosticsViewModel` is a Prism-based ViewModel for the Diagnostics module within the TestSetups subsystem. It serves as the presentation logic layer for diagnostic UI, managing view binding, user notifications, and event-driven communication with other application components. The class is designed as a shared singleton (MEF `CreationPolicy.Shared`) and acts as a bridge between the `IDiagnosticsTreeView` and the application's event infrastructure.

## 2. Public Interface

### Constructor

```csharp
public DiagnosticsViewModel(
    IDiagnosticsTreeView view,
    IRegionManager regionManager,
    IEventAggregator eventAggregator,
    IUnityContainer unityContainer)
```
Initializes the ViewModel, sets the `TreeView`'s `DataContext` to itself, creates interaction requests, and subscribes to `RaiseNotification` and `BusyIndicatorChangeNotification` events.
