## Overview

#### Purpose and entry points

NetworkGuardian is a small WPF desktop application for monitoring network state. The project is defined by `NetworkGuardian.csproj`; application startup is configured through `App.xaml` and `App.xaml.cs`. The main UI implementation is currently centered on `MainWindow.xaml.cs`, with a separate dashboard view declared in `DashboardWindow.xaml`.

#### Application shell and UI

WPF owns process startup, window lifetime, and UI-thread execution. `App.xaml` provides application-level WPF configuration, while `App.xaml.cs` is the code-behind startup/customization boundary. `MainWindow.xaml.cs` contains the primary window behavior; `DashboardWindow.xaml` represents a dashboard-oriented UI surface.

Relevant paths:
- `App.xaml`
- `App.xaml.cs`
- `MainWindow.xaml.cs`
- `DashboardWindow.xaml`

#### Network monitoring core

The monitoring domain is isolated under `core`. `core/NetworkMoniter.cs` is the likely operational component responsible for querying or observing network conditions and translating platform/network information into application-level state. This separates network inspection from UI code, allowing windows to consume monitor results rather than directly owning network logic.

Relevant path:
- `core/NetworkMoniter.cs`

#### Network-state model boundary

`models/NetworkState.cs` defines the shared state representation exchanged between monitoring logic and presentation code. It is the primary contract boundary: the monitor produces or updates network state, and UI components render that state or react to changes.

Relevant path:
- `models/NetworkState.cs`

#### Primary control and data flow

1. WPF launches the application through `App.xaml` / `App.xaml.cs`.
2. The application opens or coordinates the main window in `MainWindow.xaml.cs`.
3. UI code invokes or subscribes to `core/NetworkMoniter.cs`.
4. The monitor gathers network status from the local machine’s networking stack.
5. Results are represented by `models/NetworkState.cs`.
6. The main window and/or dashboard display the resulting state.

The key boundary is between WPF presentation (`MainWindow.xaml.cs`, `DashboardWindow.xaml`) and monitoring/domain logic (`core/NetworkMoniter.cs`, `models/NetworkState.cs`).

#### Runtime and infrastructure

The repository targets the .NET/WPF desktop runtime, as indicated by `NetworkGuardian.csproj`, `App.xaml`, and XAML window files. It appears to operate against local machine networking facilities rather than a server-side API, database, browser runtime, or cloud service. No external service integrations are evident from the supplied tree.

Relevant paths:
- `NetworkGuardian.csproj`
- `NetworkGuardian.slnx`
- `AssemblyInfo.cs`
