Dotnet Skills

Dotnet Skills is an open source catalog of installable skills and routing agents that teach AI coding assistants current .NET practice. Maintained by ManagedCode, it packages guidance for frameworks and libraries such as ASP.NET Core, Aspire, Azure Functions, Blazor, Entity Framework Core, Orleans and Semantic Kernel into skill files that Claude Code, GitHub Copilot, Gemini, Codex and Junie can load. The catalog currently lists 182 skills, 26 agents, 23 collections and 12 bundles. It is aimed at .NET developers and teams who want their coding agents to follow correct, up to date patterns rather than outdated training data. Delivery is through a global .NET tool installed from NuGet. Running the tool opens an interactive control center for browsing collections; an automatic install mode scans project files and matches skills to the NuGet packages a project already references; and bundles install a focused multi skill set, such as a quality bundle, with one command. A token command exports per skill token counts so teams can see what each skill adds to an agent's context. The website mirrors the catalog with collection, bundle, skill and agent pages, and credits the upstream projects whose guidance it draws on. Dotnet Skills is free and released under the MIT license. There is no pricing page and no paid tier. The catalog is published through a single release workflow that produces GitHub releases, NuGet packages and the website together, and automation watches official upstream releases and documentation so skills can be refreshed when guidance changes.
