EF5 코드에서 데이터베이스를 리버스 엔지니어링하려고 시도 할 때 예외가 발생합니다.

Question

이 비디오는 기존 데이터베이스에서 코드 퍼스트를 사용하는 방법을 보여줍니다. http://msdn.microsoft.com/en-us/data/jj572367

그래서 Nuget을 사용하여 EF Power Tools를 설치하고 프로젝트를 선택하고 마우스 오른쪽을 클릭하여 선택하십시오. Entity Framework -> Reverse Engineer Code First. 설명 된대로 데이터베이스를 선택하지만 OK를 클릭하면 다음 예외가 발생합니다.

System.Data.ProviderIncompatibleException: The provider did not return a ProviderManifestToken string. ---> System.InvalidOperationException: This operation requires a connection to the 'master' database. Unable to create a connection to the 'master' database because the original database connection has been opened and credentials have been removed from the connection string. Supply an unopened connection. ---> System.Data.SqlClient.SqlException: Login failed for user 'ictdev'.
