このビデオでは、既存のデータベースから Code First を使用する方法を紹介しています。 http://msdn.microsoft.com/en-us/data/jj572367
そこで、nuget を使用して EF Power Tools をインストールし、自分のプロジェクトを選択して右クリックして選択します。Entity Framework -> リバース エンジニアリング コード ファースト。説明どおりにデータベースを選択しましたが、[OK] をクリックすると次の例外が発生します。
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'.

問題は、これをどのように修正するかです。
