해결방법
위와 같은 에러메세지가 출력되면 Global.asax.cs의 Application_Start()에 다음 코드를 추가하면 된다.

Database.SetInitializer<YourDbConnection>(null);

 

protected void Application_Start()
{
    AreaRegistration.RegisterAllAreas();

    // Use LocalDB for Entity Framework by default
    Database.DefaultConnectionFactory = new SqlConnectionFactory(@"Data Source=(localdb)\v11.0; Integrated Security=True; MultipleActiveResultSets=True");
    Database.SetInitializer<NihConnection>(null);
    RegisterGlobalFilters(GlobalFilters.Filters);
    RegisterRoutes(RouteTable.Routes);
}
