    The cause: The MVC entity framework connection string contains incorrect meta data. Several entity models for several databases were used in the project.

    The cause:

    You’ll probably run into this issue if you’re utilizing the connection string created while importing the EDMX file using in:base(“EDMXConnString”).

    Solution: By establishing a common connection string that referred to the database containing the ASP.NET Identity tables, you were able to resolve the error: the entity type applicationuser is not part of the model for the current context.

    <add name=MyConnString connectionString=Data Source=server; Initial Catalog=db_name; User ID=user_id; Password=password; Connect Timeout=60; providerName=System.Data.SqlClient />

    It then will work when you use the connection string in :base.

    public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
public ApplicationDbContext()
: base(MyConnString)
{
}
}

    To ensure that a context instanciation is not missed, the code should be as follows:

    UserManagerFactory = () => new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(new ApplicationDbContext()));
