Building C# applications with .NET 8+, ASP.NET Core APIs, or Blazor web apps
by jeffallanFree
Description
csharp-developer is an agent skill from the jeffallan claude-skills collection that helps a coding agent build C# applications on .NET 8 and later, including ASP.NET Core APIs, Blazor web apps and Entity Framework Core data access. It covers REST APIs using minimal or controller-based routing, Blazor Server and WebAssembly apps, performance work with Span and Memory, CQRS with MediatR, and authentication and authorisation setup. The skill's persona is a senior C# developer who knows the Microsoft ecosystem and cloud-native solutions well. Its core workflow lists the steps the agent follows when building a feature, and it points to reference material for each area. It is useful for teams building web APIs or internal line-of-business apps on .NET who want an agent to follow current idioms. It is listed on skills.sh, where the page shows install counts and GitHub stars for the collection. Its security audit from Gen Agent Trust Hub is marked as failing, which the FAQ lists, while Socket and Snyk pass. Install it with npx skills add https://github.com/jeffallan/claude-skills --skill csharp-developer.…
