The oft cited reference that the frameworks are compatible is <a href="https://github.com/IdentityServer/IdentityServer3/blob/vNext/source/HostvNext/Config/IApplicationBuilderExtensions.cs" rel="nofollow">an extension method build by Thinktecture for supporting their IdentityServer3 on ASP.NET 5</a>.

That method is specific to IdentityServer and does not support the request being processed by any middleware registered later in the AspNet pipeline (it does not call the next component).

This adapts the method to address those shortcomings:

<pre><code>internal static class IApplicationBuilderExtensions
{
 public static void UseOwin(
 this IApplicationBuilder app,
 Action&lt;IAppBuilder&gt; owinConfiguration )
 {
 app.UseOwin(
 addToPipeline =&gt;
 {
 addToPipeline(
 next =&gt;
 {
 var builder = new AppBuilder();

 owinConfiguration( builder );

 builder.Run( ctx =&gt; next( ctx.Environment ) );

 Func&lt;IDictionary&lt;string, object&gt;, Task&gt; appFunc =
 (Func&lt;IDictionary&lt;string, object&gt;, Task&gt;)
 builder.Build( typeof( Func&lt;IDictionary&lt;string, object&gt;, Task&gt; ) );

 return appFunc;
 } );
 } );
 }
}
</code></pre>

It can be used as follows:

<pre><code>app.UseOwin(
 owin =&gt;
 {
 // Arbitrary IAppBuilder registrations can be placed in this block

 // For example, this extension can be provided by
 // NWebsec.Owin or Thinktecture.IdentityServer3
 owin.UseHsts();
 } );

// ASP.NET 5 components, like MVC 6, will still process the request
// (assuming the request was not handled by earlier middleware)
app.UseMvc();
</code></pre>

<hr>

Here's a slightly different version, that uses <code>AppBuilder.DefaultApp</code>:

<pre><code>public static IApplicationBuilder UseOwinAppBuilder(this IApplicationBuilder app, Action&lt;IAppBuilder&gt; configuration)
{
 if (app == null)
 {
 throw new ArgumentNullException(nameof(app));
 }

 if (configuration == null)
 {
 throw new ArgumentNullException(nameof(configuration));
 }

 return app.UseOwin(setup =&gt; setup(next =&gt;
 {
 var builder = new AppBuilder();
 var lifetime = (IApplicationLifetime) app.ApplicationServices.GetService(typeof(IApplicationLifetime));

 var properties = new AppProperties(builder.Properties);
 properties.AppName = app.ApplicationServices.GetApplicationUniqueIdentifier();
 properties.OnAppDisposing = lifetime.ApplicationStopping;
 properties.DefaultApp = next;

 configuration(builder);

 return builder.Build&lt;Func&lt;IDictionary&lt;string, object&gt;, Task&gt;&gt;();
 }));
}
</code></pre>

Note that referencing <code>Microsoft.Owin</code> makes your app incompatible with <code>dnxcore50</code> (Core CLR).

ASP.NET 5 (aspnet vnext) is OWIN based like Katana was, but has different abstractions. Notably <code>IAppBuilder</code> has been replaced by <code>IApplicationBuilder</code>. Many middleware libraries depend on <code>IAppBuilder</code> and have not been updated to support ASP.NET 5

How can I use this OWIN middleware in APS.NET 5 middleware. Both are OWIN based so it should be possible.

<code>Microsoft.AspNet.Builder.OwinExtensions</code> does provide a <code>UseOwin</code> method, but it is based on the low-level OWIN signatures so cannot be used with methods expecting <code>IAppBuilder</code>.

ASP.NET 5 (aspnet vnext)像Katana一样基于OWIN，但具有不同的抽象。值得注意的是，IApplicationBuilder已经取代了IAppBuilder。许多中间件库依赖于IAppBuilder，尚未更新为支持ASP.NET 5如何在APS.NET 5中间件中使用该中间件。两者都是基于OW...
