发帖数: 579 | 1 I am working on RESTful Web services design in Visual Studio 2013 on Windows
7.
I need to run the command of Update-Database to create the database in code-
first migrations in a project.
But I get an error:
System.Data.SqlClient.SqlException : Cannot attach the file 'C:MyPathApp
_DataProductReview_newContext-20150216131927.mdf' as database 'ProductReview
_newContext-20150216131927'.
at System.Data.ProviderBase.DbConnectionPool.TryGetConnection(
DbConnection owningObject, UInt32 waitForMultipleObjectsTimeout, Boolean
allowCreate, Boolean onlyOneCheckConnection, DbConnectionOptions userOptions
, DbConnectionInternal& connection)
Thanks ! |
