Hello,
I have problems connecting to local mdf database. I'm using VS2012 Express. Below is connection string:
<add name="CompanyDataConnectionString"
connectionString="Data Source=(LocalDB)\v11.0;AttachDbFilename=|DataDirectory|\MyDatabase.mdf;Integrated Security=True;Connect Timeout=30;Provider=SQLOLEDB"
providerName="System.Data.SqlClient" />
And here is the error:
System.Data.OleDb.OleDbException was unhandled by user code
Message=No error message available, result code: DB_E_ERRORSOCCURRED(0x80040E21).
Source=System.Data
ErrorCode=-2147217887

I'm using SQL Server 2012, windows authentication. Or you can try to show me how to connect directly to SQL Server database. Any solution is welcome.
Thanks
