OWIN Startup Class Missing

Question

I\'m getting this error as my project is not able to find the reference for OWIN startup class. I\'ve even installed all the OWIN reference packages through Nug

Answer 1

While I can't fully explain why this solved the issue for me, I ran into a problem like this after I changed my API project to build to separate \debug and \release folders. Once I reverted that change back to build to a single \bin folder things started working.

I wrote up my experience here: Can't get the OWIN Startup class to run in IIS Express after renaming ASP.NET project file
