The issue you're seeing is directly due to the fact you're referencing both ASP.NET Identity 2 and Identity 3 packages: Identity 2 references IdentityModel 4 (that comes with the full .NET framework) while the new stack uses IdentityModel 5. Sadly, both are incompatible and can't be referenced in the same project. You can find more information here: Ambiguous reference issue (Microsoft.AspNet.Identity & Microsoft.AspNet.Identity.Core)

Remove your Microsoft.AspNet.Identity.Owin/Microsoft.Owin.Security references and it should work.
