title: OAuth2 Authorization Server for .NET
body: <p>I am currently prototyping OAuth2 authorization server options, and want to use <a href="https://github.com/IdentityServer/IdentityServer4" rel="nofollow noreferrer">IdentityServer4</a>.</p>
  
  <p>But it would require alot of work to put an ASP.NET Core App on top of the current .NET Framework stack (v4.5) that I am working on. This stack also relies heavily on the IoC container <a href="http://springframework.net/" rel="nofollow noreferrer">"Spring"</a>, so thats another issue.</p>
  
  <p>I have tried looking at <a href="https://github.com/aspnet-contrib/AspNet.Security.OpenIdConnect.Server" rel="nofollow noreferrer">ASOS</a>, but I run in to similar problems.</p>
  
  <p>Isn't there a proper OAuth2 authorization server framework made for good old ASP.NET that is still being maintained?</p>
  
  <p>Maybe some of you have some input to how you solved a similar situation?</p>
