Using " User Instance" on a local SQL Server Express instance " Data Source=.\SQLExpress; integrated security=true; attachdbfilename=|DataDirectory|\mydb.mdf; user instance=true; " 
The " User Instance" functionality creates a new SQL Server instance on the fly during connect. This works only on a local SQL Server 2005 instance and only when connecting using windows authentication over local named pipes. The purpose is to be able to create a full rights SQL Server instance to a user with limited administrative rights on the computer. To enable the functionality: sp_configure ‘user instances enabled‘,‘1‘ (0 to disable)
Using SQL Server 2005 Express? Don‘t miss the server name syntax: SERVERNAME\SQLEXPRESS (Substitute " SERVERNAME" with the name of the computer)
Context Connection - connecting to " self" from within your CLR stored prodedure/function
Context Connection - connecting to " self" from within your CLR stored prodedure/function

When to use SQL Native Client? .Net applications
Do not use the SQL Native Client. Use the .NET Framework Data Provider for SQL Server (SqlConnection). 
COM applications, all other then .Net applications
COM applications, all other then .Net applications
Use the SQL Native Client if you are accessing an SQL Server 2005 and need the new features of SQL Server 2005 such as MARS, encryption, XML data type etc. Continue use your current provider (OLE DB / ODBC through the MDAC package) if you are not connecting to an SQL Server 2005 (that‘s quite obvious eh..) or if you are connecting to an SQL Server 2005 but are not using any of the new SQL Server 2005 features.
