Pull Request Overview

This PR introduces a GitHub Actions workflow to build, test, sign, and package the WPF desktop application as an MSIX, and adjusts project and code files to support theming, logging, and packaging.

• Add .github/workflows/dotnet-desktop.yml to automate build, test, and MSIX packaging.
• Update .csproj and resource files to include theme XAML dictionaries and demo boards data.
• Refactor application startup (App.xaml.cs), main window (MainWindow.xaml(.cs)), and introduce ILogger abstraction for unified logging.

Solver/src/BoardSolution.cs:1

• This file uses List<T> and HashSet<T> but lacks using System.Collections.Generic;, which will cause compilation errors. Add the appropriate using directive.

namespace Solver;

Solver/src/App.xaml.cs:35

• [nitpick] The pack URI uses /src/Resources/…, but packaging may expect /Resources/… without the src folder. Verify the resource path matches the output assembly structure.

string themeUriString = theme == AppTheme.Dark

Calling GetDirectoryName can return null (e.g., if path has no directory component), leading to ArgumentNullException. Add a null check before creating the directory.

Suggested change

	Directory.CreateDirectory(Path.GetDirectoryName(_filePath));
	var directoryPath = Path.GetDirectoryName(_filePath);
	if (directoryPath != null)
	{
	Directory.CreateDirectory(directoryPath);
	}
