No OWIN authentication manager is associated with the request

Question

After trying to enable owin & AspNet Identity to my Web Api project (in VS 2013 + .Net 4.5.1) I get the following error in each valid or unvalid(request to none exist co

Answer 1

if you don't actually need OWIN you can simply uninstall it.

one way to do it is in Nuget Manager uninstall every OWIN library, the order will be dictated by their dependencies.

after this is done you don't need any OWIN related code or config. this worked out best for me since I am using windows auth.
