simplemembership

I noticed that someone else has faced the same problem such as Cannot insert the value NULL into column 'UserId' but it should be caused by different reasons. The problem can be simplified like this: UsersContext _usersContext = new UsersContext(); ... var usersInRole = new UsersInRole() { RoleId = 3, UserId = 1 }; _usersContext.UsersInRoles.Add(usersInRole); _usersContext.SaveChanges(); The last line of code threw an exception "An error occurred while updating the entries. See the inner exception for details." , and the InnerException was saying the same thing "An error occurred while

I've been looking around various SO questions, blog posts, and so forth regarding the changes to membership providers in MVC 4.

The code looks like this : WebSecurity.InitializeDatabaseConnection("DALEntities", "tblContacts1", "ContactID", "EMail", autoCreateTables: true); I am not sure what DataProvider is failing.

I'm about to go insane, so I'll try getting some help one more time... I'm using Visual Studio Express 2012 for Web to create an internet project using C# + MVC4 + Razor + Entity Framework + ASP.NET 4.5. I need to do the following: automatically create an "admin" user (who will be authorized all over the site) and then create some user roles. I've read about SimpleMembership, roles and everything all over the web, but nothing seems to give me a straightforward method to make the whole thing work. This is what I've done so far: 1- Created a DataContext class: public class DataContext :
