## What it does

The plugin turns an OpenAPI specification into a .NET application. It can scaffold an ASP.NET Core project and generate controllers; its description also mentions Entity Framework integration and C# best practices.

It includes the slash command `/openapi-to-application-csharp-dotnet:openapi-to-application-code` and the `openapi-to-application` agent. The command generates an application from a specification, while the agent assists with the task. Install it when you use GitHub Copilot and want to build a .NET project from an OpenAPI definition.
