Why is [Owin] throwing a null exception on new project?

Question

I have a rather strange issue i\'m not sure how to fix or if i can even fix it.

I\'ve done some research into the issue but can\'t find an answer to what\'s causing

Answer 1

Running the following updates after creating a new project worked for me:

update-package Microsoft.Owin

update-package Microsoft.Owin.Security

update-package Microsoft.Owin.Security.Cookies

I think the last one might have been enough. I am using Visual Studio 2013 (12.0.21005.1) and the ASP.Net Web Application template with Web API.
