在IIS APP_DATA文件夹中不在远程SQL Server本地创建的ASP.NET EF数据库

Question

I'm creating my first ASP.NET, EF code first web app.

The problem I have is in deploying and running it on a local IIS machine that is remote to the SQL Server Express ( SYSDEVSERVER ).

I'm unable to formulate a connection string that creates the EF DB in the App_Data folder of the web app. Instead, the remote DB server, create a DB local to itself.

The connection string that works (so far) is as follows:

<add name="MyWebApp" 
     connectionString="Data Source=SYSDEVSERVER\SQLEXPRESS; user id=USER;password=PASSWORD; Initial Catalog=MyDB; Trusted_Connection=no;" 
     providerName="System.Data.SqlClient" />

OK, so I'm not specifying an AttachDbFileName to say that the DB is in the App_Data folder of the web app - that's why the DB is created on the server.

If I do specify AttachDbFilename like this:

AttachDbFilename=|DataDirectory|\MyDB.mdf

I get an error message

Invalid value for key 'attachdbfilename'

So far, I've been unable to resolve this, so for now I'll have to accept the DB residing local to the remote server, but I'm not too happy about it.

Does anyone know what connection string to use that allows the database to be created in the App_Data folder?

Thanks

For local DB a conection string in this format should work

<add name="MyWebApp" 
 connectionString="Data Source=(localdb)\v11.0;AttachDbFilename=|DataDirectory|\MyDB.mdf;Initial Catalog=MyDB;Integrated Security=True;"
 providerName="System.Data.SqlClient" />
