I have been searching for an hour trying to figure out why this isn\'t working.
I have a ASP.Net MVC 5 application with a WebAPI. I am trying to get Request.GetOwin
None of these worked for me. I had to compare Nuget packages with one that was created with Identity and I found this Nuget package missing which when added fixed the issue for me
Microsoft.Owin.Host.SystemWeb
Apparently you need it to run OWIN on IIS using the ASP.NET request pipeline (read you're screwed without it!)
