A few weeks ago I gave a CAS presentation at an MSDN code camp. While preparing for the talk I ran across an interesting "feature" in the Fx Beta 2 Configuration tool (Control Panel > Administrative Tools > Microsoft .NET Framework 2.0 Configuration). When I create a new code group named "foo" (in any policy) the name assigned to the code group mysteriously becomes "Copy of foo". If I create a code group named "Copy of foo", the newest code group is mysteriously named "Copy(2) of foo". Clearly there is a duplicate name check that is not properly applied!

The "feature" is minor, but annoying. All that is needed as a work-around is to rename the code group after-the-fact.

I have submitted this "feature" to MSFT for review - hopefully it won't make it into the release.
