# WPF Solution and Project Structure

A guide for designing WPF project solution and project structure based on Clean Architecture.

## Template Project

The templates folder contains a .NET 9 Clean Architecture WPF solution example.

```
templates/
├── GameDataTool.sln                    ← Solution file
├── Directory.Build.props               ← Common build settings
├── src/
│   ├── GameDataTool.Domain/            ← 🔵 Core - Pure domain models
│   ├── GameDataTool.Application/       ← 🟢 Core - Use Cases
│   ├── GameDataTool.Infrastructure/    ← 🟡 Infrastructure - External systems
│   ├── GameDataTool.ViewModels/        ← 🟠 Presentation - ViewModel
│   ├── GameDataTool.WpfServices/       ← 🟠 Presentation - WPF services
│   ├── GameDataTool.UI/                ← 🔴 Presentation - Custom Controls
│   └── GameDataTool.WpfApp/            ← 🔴 Composition Root
└── tests/
    ├── GameDataTool.Domain.Tests/
    ├── GameDataTool.Application.Tests/
    └── GameDataTool.ViewModels.Tests/
```

## Solution Structure Principles

**Solution name is the application name**
- Example: `GameDataTool` solution = executable .NET Assembly name

## Project Structure (Clean Architecture)
