c# Add As Link not working (always copies to Project folder?)

c# VS2008 SP1

right Click on Project na开发者_运维技巧me, Add Existing Item, selecting Add As Link from the drop down menu, and selecting a .cs file outside of the project folder, causes the file to be copied locally within the project folder.

This is surely not the correct behavior?

Right Click on Project name, Add Existing Item, selecting a .cs file outside of the project folder AND THEN Add As Link from the drop down menu.

That is the default behavior. Also confirmed with Visual Studio 2010

Doesn't do that for me. Are you selecting the file you want first, and then selecting "Add as link" in the weird dropdown button?
