# Documentation: ShellView.xaml.cs

## 1. Purpose

`ShellView` is the main shell window component for the DTS Viewer application. It serves as the primary container/view for the application's user interface, implementing the `IShellView` interface to integrate with the broader system architecture. The class handles window initialization and ensures the application launches in a maximized state.

## 2. Public Interface

### `ShellView` (class)
**Signature:**
```csharp
public partial class ShellView : IShellView
```

**Description:** A WPF window control that serves as the application's main shell. Implements `IShellView` from `DTS.Common.Interface`.

---

### `ShellView()` (constructor)
**Signature:**
```csharp
public ShellView()
```

**Description:** Default constructor that initializes the window component and sets the initial window state.

**Behavior:**
1. Calls `InitializeComponent()` to load the XAML-defined UI
2. Sets `this.WindowState = WindowState.Maximized` to launch the window in maximized mode

## 3. Invariants

- The window will always initialize in a maximized state (`WindowState.Maximized`).
- The class is a partial class, implying a companion XAML file (`ShellView.xaml`) must exist and define the visual tree.
- The class must implement `IShellView`, though the specific interface members are not visible in this source file.

## 4. Dependencies

### This module depends on:
- **`System.Windows`** - WPF framework for window management (`Window`, `WindowState`, `ResizeMode`)
- **`DTS.Common.Interface.IShellView`** - Interface contract this view implements

### What depends on this module:
- Cannot be determined from this source file alone. Likely consumed by a bootstrapper, main entry point, or an IoC container that resolves `IShellView`.

## 5. Gotchas

- **Commented-out `StateChanged` handler:** There is disabled code that would have toggled `ResizeMode` between `ResizeMode.NoResize` (when maximized) and `ResizeMode.CanResize` (otherwise). The reason for commenting this out is unclear from source alone—this may be intentional behavior removal or a pending fix.
- **No explicit interface implementation visible:** The source shows `IShellView` is implemented, but no interface members are explicitly defined in this file. They may be auto-implemented properties or defined in the XAML code-behind.
