# Documentation: NavigationView

## 1. Purpose
This module serves as the code-behind file for the `NavigationView` component within the `DTS.Viewer` application. It acts as the UI container for navigation controls, initializing the XAML component tree. It implements the `INavigationView` interface, suggesting it is part of a larger navigation architecture (likely MVP or MVVM) where the view is abstracted behind an interface for decoupling or testing purposes.

## 2. Public Interface

### Class: `NavigationView`
**Inherits:** `INavigationView` (from `DTS.Common.Interface`)
**Type:** `partial` class

#### Constructor
*   **`public NavigationView()`**
    *   **Description:** Default constructor. Calls `InitializeComponent()`, which loads and initializes the associated XAML layout defined in `NavigationView.xaml`.

## 3. Invariants
*   **Initialization Order:** The `InitializeComponent()` method is invoked immediately upon construction. The object is not fully functional until this method completes.
*   **Partial Definition:** This class is defined as `partial`. It relies on auto-generated code (typically from `NavigationView.g.i.cs`) created by the WPF build process to provide the implementation of `InitializeComponent` and connect to the XAML elements.

## 4. Dependencies
*   **External Dependencies:**
    *   `DTS.Common.Interface`: Required for the `INavigationView` interface definition.
    *   **WPF System Assemblies:** Implicitly depends on `System.Windows.Controls` (and related namespaces) for `UserControl` functionality, though not explicitly visible in the `using` statements (likely defined in the XAML root element).
*   **File Dependencies:**
    *   **`NavigationView.xaml`**: This code-beind file is tightly coupled to a corresponding XAML file which defines the visual structure.

## 5. Gotchas
*   **Missing Interface Implementation Details:** The source code shows that `NavigationView` implements `INavigationView`, but it does not explicitly implement any methods or properties in this file. The implementation is likely defined explicitly in the XAML (via bindings) or is expected to be an empty marker interface, but this cannot be confirmed without the interface definition.
*   **Logic Location:** There is no logic present in this file other than initialization. Developers should look to the associated XAML file for UI element definitions and potentially the ViewModel/Presenter for actual behavior logic.
