I read the previous posts - Tried a few things. Here is the issue A simple console OWIN self host app - Not much in there public void Configuration(IAppBuilder appBuilder) does not compile. 1. If I say using Microsoft.Owin and using Owin, then I get an error the using directive for owin already appeared. I can't figure out why. 2. If I do using Microsoft.Owin but modify the use as Owin.IAppBuilder then the compiler says it can't find owin.IAppBuilder.
Yes I tried reinstalling Microsoft.Owin and Owin (3 times) I checked the project reference 4.5.1
