ClaimesIdentityFactory broken when upgrade to AspNet.Identity.Core v2 #39

hi Pranav

After doing an update of the all Nuget packages including to AspNet.Identity.Core v2 ...

In IdentityExtensions\MyClaimsIdentityFactory.cs
Error:
The type 'TUser' must be a reference type in order to use it as parameter 'TUser' in the generic type or method 'Microsoft.AspNet.Identity.ClaimsIdentityFactory'

The fix is to change:

public class MyClaimsIdentityFactory<TUser> : ClaimsIdentityFactory<TUser> where TUser : IUser<string>

to

public class MyClaimsIdentityFactory<TUser> : ClaimsIdentityFactory<TUser> where TUser : class, IUser<string>

I'll learn how to do a Git Pull request and see if I can add it to the repo ....

regards
Rob
