Hi all,
Upgraded from SQL Server 2005 to 2008, now when my app tries to execute If Membership.GetUser() Is Nothing Then it says A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified).  Confused as to whether this is a problem connecting to ASPNETDB.MDF or my DB in general so I went into Server Explorer and created a connection to my DB, tested successfully, then grabbed the connection string. It matches what's in my web.config so I think the problem is ASPNETDB.MDF only works with SQL Server 2005 Express. If this is true, what do I need to do to use this app with SQL 2008? Should I just delete ASPNETDB.MDF?
thank you,
Rob
