@derek.williams @craigsch @development1 This is a dependency issue which, according to my current investigations, appear to be out outside of our control.
Underlying problem appears to be incompatibility with System.IdentityModel.Tokens.Jwt 5.x, which is what the OWIN 4.x libs depend on.
Bottom line is, you need to use OWIN 3.x and specifically System.IdentityModel.Tokens.Jwt 4.x
I will see that we add a big notice on the Quickstart regarding this.
@jerdog Can you please keep an eye out on these symptoms, specifically when using OWIN Web API, as other may run into it as well?
