I'm using PostSharp 4.2.22.0 and Owin 3.0.1 in my project.
When I compile I get the following error:
Unhandled exception (4.2.22.0, postsharp-net40-x86-srv.exe, CLR
4.0.30319.394271, Release): PostSharp.Sdk.CodeModel.AssemblyLoadException: Cannot find assembly 'microsoft.owin.security, version=2.1.0.0, culture=neutral, publickeytoken=31bf3856ad364e35'. [Version mismatch]
But was does PostSharp have to do with Owin? Why is the Owin version important for PostSharp, these are two totally different packages.
