Asp.net Identity: Registry Error

I created an ASP.NET MVC project with "Individual User Accounts" authentication and then I ran it and tried to make a record, however the following exception was thrown at line 155:

Linha 154: var user = new ApplicationUser
                      {
                         UserName = model.Email, Email,
                         Email =   model.Email
                      };
Linha 155: var result = await UserManager.CreateAsync(user, model.Password);

Message:

You're giving this error, but when I log in to the [My-Server] \ SQLEXPRESS server with Windows Authentication, I can access it normally. Just make that mistake in ASP.NET Identity itself.
