Microsoft.AspNetCore.Owin 10.0.0-preview.2.25164.1

About

Microsoft.AspNetCore.Owin provides adapters for running OWIN middleware in an ASP.NET Core application, and to run ASP.NET Core middleware in an OWIN application.

How to Use

To use Microsoft.AspNetCore.Owin, follow these steps:

Installation

dotnet add package Microsoft.AspNetCore.Owin

Configuration

To use OWIN middleware in an ASP.NET Core pipeline:

1. Define the OWIN middleware, if not done already. Here's a basic "Hello World" example:

   public Task OwinHello(IDictionary<string, object> environment)
   {
       var responseText = "Hello World via OWIN";
       var responseBytes = Encoding.UTF8.GetBytes(responseText);
   
       // OWIN Environment Keys: https://owin.org/spec/spec/owin-1.0.0.html
       var responseStream = (Stream)environment["owin.ResponseBody"];
       var responseHeaders = (IDictionary<string, string[]>)environment["owin.ResponseHeaders"];
   
       responseHeaders["Content-Length"] = [responseBytes.Length.ToString(CultureInfo.InvariantCulture)];
       responseHeaders["Content-Type"] = ["text/plain"];
   
       return responseStream.WriteAsync(responseBytes, 0, responseBytes.Length);
   }
   

2. Add the middleware to the ASP.NET Core pipeline with the UseOwin extension method. For example:

   app.UseOwin(pipeline =>
   {
       pipeline(next => OwinHello);
   });
