     public DbSet<User> User { get; set; }
 }

and create controller but i have a error

Unable to retrieve metadata for 'WSDashboard.Models.User'. Using the same DbCompiledModel to create contexts against different types of database servers is not supported. Instead, create a separate DbCompiledModel for each type of server being used.
