Where is microsoft.interop.security.azroles on Server 2008 R2?

As far as I can recall, on Server 2003, microsoft.interop.security.azr开发者_StackOverflow中文版oles used to live in "C:\Windows\Microsoft.NET\authman". On Server 2008 R2, that folder is empty.

Anyone know where it's hiding?

I had the same problem, myself. They've put it back in the GAC, in both 32-bit and 64-bit flavours:

gacutil /l Microsoft.Interop.Security.AzRoles

I found a copy in a subfolder of C:\Windows\winsxs. I have SQL Server 2008 loaded on this box.
