Question

Im following plural sight tutorial for learning the MVC4 and the entity framework.
Im running into trouble when i click login, the user and password is being save corectly in the database however i get a
Exception Details: System.InvalidOperationException: To call this method, the "Membership.Provider" property must be an instance of "ExtendedMembershipProvider".
error when i try to run Update-Database
here is my method that seeds the database
protected override void Seed(eManager.Web.Infrastructure.DepartmentDb context)
{
context.Departments.AddOrUpdate(d => d.Name,
new Department() { Name = "Engineering" },
new Department() { Name = "Sales" },
new Department() { Name = "Shipping" },
new Department() { Name = "Human Resources" });
if (Roles.RoleExists("Admin"))
{
Roles.CreateRole("Admin");
}
if (Membership.GetUser("rlemie") == null)
{
Membership.CreateUser("rlemie", "jumanji");
Roles.AddUserToRole("rlemie", "Admin");
}
}
}
and here is my web-config

my Accountcontroller.cs is different from the one in the pluralsight tutorial, as it uses a
[InitializeSimpleMembership] and has a slightly different routing structure.
I would prefer an answer that explains what exactly I am doing wrong, because I have a workaround that fixes it but im not sure exactly why, and it causes more problems down the road
