Another of these 'somebody told me this is true'...I wasn't able to reproduce it, but figured I'd ask.

Someone told me that if a WinForm app is utilizing Web Services (say, to access a layer that's connected to SQL Server), that while 'connected' to a Web Service, the WinForm cannot write information to the local hard disk. Apparently, it is because of a new security model in .NET.

This sounds pretty crazy, as a WinForm that is utilizing a Web Service might need to write data locallly (like store user selections, user preferences, etc.)

Can anyone shed any light on this?

Thanks,
Kevin
