I am using Visual Studio 2005 on Vista. I have a couple of attached network drives. Whenever I try to access code on those network drives I get a warning saying that the network drive is not trusted. On my old XP machine I had to setup the .NET Framework Configuration to make this work, however I don't see anything like this on Vista for .NET framework 3.0. So.. where do I set the trust relationships with my network drives in Vista?

Use the Microsoft .NET framework 2.0 configuration MMC (search for it using the Start menu), since 3.0 apps use the 2.0 runtime you should be able to configure CAS policy for it there.
