I've written a small Visual Studio extension that is a project template for creating ASP.NET MVC 5 applications using ASP.NET Identity, WCF Services and the Telerik OpenAccess ORM.
More specifically (related to Telerik) I've created a version of the Microsoft.AspNet.Identity.IUserStore<TUser>, IUserPasswordStore<TUser>, IUserClaimStore<TUser>, IUserRoleStore<TUser>, IUserSecurityStampStore<TUser>, IUserLoginStore<TUser> which can be used inside of Microsoft.AspNet.Identity.UserManager<TUser> but utilizes the Telerik OpenAccess ORM rather than the Entity Framework. I've also written a blog post that goes into a tad more detail
If you're interested in the straight source code for it you can just download it here
or the extension can be downloaded here
Hopefully this is useful to someone (and nobody minds me posting it here)!
