OWIN Tools

OWIN Tools

Generate a new OWIN Startup.cs by picking middleware (CORS, static files, cookie/OAuth authentication, Web API, SignalR, session, error page); or paste an existing OWIN Configuration(IAppBuilder app) method and migrate it to a .NET 6+ minimal-hosting Program.cs with a per-line breakdown of what changed. Includes a standalone OWIN → ASP.NET Core middleware reference table.

Emits app.Use<TypeName>(); — leave blank to skip.

Check the middleware you need — the code regenerates live. Order follows common OWIN convention (CORS/static files first, auth next, then Web API/SignalR); see inline comments for anything left ambiguous.
