I follow Scott Allen's tutorial through MVC 4. He talks about InitializeSimpleMembershipAttributes file inside Filters folder. I can't find any of it in my solution. What did I do wrong?
There is no Filters folder in MVC5. The Filters folder is there for the SimpleMembership filters that were introduced in MVC4. MVC5 does not use SImpleMembership, but uses ASP.NET Identity which does not have those filters, thus no filter folder is present.
