标 题: error .mdf file unable to attach in Visual Studio 2013 win 7
发信站: BBS 未名空间站 (Mon Feb 16 19:26:34 2015, 美东)
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 !
