Hello,
since a couple of days I'm working on a problem with the SQL Server Express (32-Bit as well as 64Bit).
I installed a new SQL Server 2008 with an instance named SQL2012 and the Management Studio 2008 R2 on the same machine. I easily am abled to connect to the Server using the Management Studio with several Server Name settings (localhost, IP, (local), .\SQL2012).
Now I have a self-written programm (C#) wich should connect to the Server, but it does not work. It is definitely not a problem of the programm code because the same programm is abled to connect to a SQL Server 2008 Enterprise Edition. Similar Problem with
the 2012 Express Version (2012 Enterprise not tested).
The connection string I use and wich is working with connecting on the Enterprise Edition is: Server=Servername\Instance;Database=DatabaseName;User Id=user;Password=password;
Anybody any solution why the Express-Version refuses to connect?
