Can I use datasource=.\\\\SQLEXPRESS or do I need to now use: machinename\\\\SQLEXPRESS

Question

Can I still use datasource=.\SQLEXPRESS or do I need to change it to : machine_name\SQLEXPRESS for a local instance of SQL Server 2008 Express in C#?

My connection string worked fine in SQL Express 2005, but with the same settings no longer works for 2008.

Answer 1

Assuming the instance name is indeed SQLEXPRESS, using .\SQLEXPRESS will work locally.

Use the SQL Server Configuration Manager to find out the correct instance name.

Answer 2

What is the final purpose of the app as it more conventional to include pc name.
