In Visual Studio 2005, you may experience this error when you want to add a Database to your project.
The reason is that the “SQL Server Instance Name” setting in the Data Connections is incorrectly configured.
Run Visual Studio 2005 to correctly configure the “SQL Server Instance Name” setting in Visual Studio 2005. Then follow these steps in order:
– “Database Tools”,
– “Data Connections”,
– “SQL Server Instance Name”
In the “SQL Server Instance Name” box, enter the name of a valid Instance. If you are using SQL Server Instance as “Default Instance”, then leave this box blank.
