Code Maze is a blog about C# and .NET, written with simplicity and pragmatism in mind. The articles are hands-on. They focus on the core of each topic and show working code, not theory alone.
This repository holds that code. If you came here from an article, the article links to its exact folder. If you are just browsing, pick a topic below.
You need the .NET SDK. Each project states its target framework in its .csproj file, so install the version that project asks for.
git clone https://github.com/CodeMazeBlog/CodeMazeGuides.git cd CodeMazeGuides/<topic>/<article-folder> dotnet build dotnet run dotnet test
Tip
The full repository is large. To get only one article, use a sparse checkout:
git clone --filter=blob:none --sparse https://github.com/CodeMazeBlog/CodeMazeGuides.git cd CodeMazeGuides git sparse-checkout set <topic>/<article-folder>
The numbers show how many article projects each folder holds.

Each article is self-contained. You never need to build the whole repository.
Found a bug in an example, or does a project not build on a newer .NET version? Open an issue or send a pull request. The PR build checks every changed project automatically.
