# Documentation: ShellView.xaml.cs

## 1. Purpose

`ShellView` is the main shell window component for the DTS Viewer application. It serves as the primary container/window for the WPF-based viewer interface, implementing the `IShellView` contract to integrate with the broader application architecture. This code-behind file handles window initialization and state management for the shell view.

## 2. Public Interface

### Class: `ShellView`
- **Namespace:** `DTS.Viewer.Loader`
- **Inherits from:** `Window` (WPF base class, implicit via `InitializeComponent()` and `WindowState` usage)
- **Implements:** `IShellView` (from `DTS.Common.Interface`)

#### Constructor: `ShellView()`
```csharp
public ShellView()
```
**Behavior:** Initializes the XAML component via `InitializeComponent()` and immediately sets the window state to maximized (`WindowState.Maximized`). This ensures the shell window opens in a maximized state by default.

## 3. Invariants

- The window will always initialize in a maximized state; there is no configuration or conditional logic to alter this behavior.
- `ShellView` must implement `IShellView` to satisfy the contract expected by other components in the system (exact members of `IShellView` are not visible in this source file).
- `InitializeComponent()` must be called before any UI element access; this is guaranteed by the constructor ordering.

## 4. Dependencies

### This module depends on:
- **`System.Windows`** - WPF framework for `Window`, `WindowState`, and `DependencyObject` infrastructure.
- **`DTS.Common.Interface.IShellView`** - Interface contract that `ShellView` implements.

### What depends on this module:
- Not determinable from this source file alone. The `IShellView` interface consumers and any XAML references would be the dependents, but these are not visible here.

## 5. Gotchas

- **Commented-out `StateChanged` handler:** There is disabled code that would toggle `ResizeMode` between `NoResize` (when maximized) and `CanResize` (otherwise). The reason for commenting this out is unclear from source alone—it may represent abandoned functionality, a bug workaround that is no longer needed, or tech debt.
- **Hardcoded maximized state:** The window always opens maximized with no way to configure this behavior from outside the constructor. If different initial window states are needed, this would require modification.
