Property Value


A string value representing the assembly's subtype. For SQL Server Visual Basic or Visual C# projects, this property is set to SQLCLR if the reference was retrieved from the target SQL server.



This example adds a reference to an open Visual Basic or Visual C# project and displays the reference subtype, if one exists. To run this example as an add-in, see How to: Compile and Run the Automation Object Model Code Examples.

The default paths for the reference added is: <drive>:\Program Files\Microsoft SQL Server\90\COM. Replace <file path> in the example with this or another appropriate file path.

This property is useful only on SQL Server Visual Basic or Visual C# projects.
