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:

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);
}

Add the middleware to the ASP.NET Core pipeline with the UseOwin extension method. For example:
```
app.UseOwin(pipeline =>
{
    pipeline(next => OwinHello);
});
```

Additional Documentation

For additional documentation, including examples on running ASP.NET Core on an OWIN-based server, refer to the official documentation on OWIN with ASP.NET Core.
