Any known issues with VISTA SP1 and building the solution? Everything is runs great on our XP workstations and on Windows 2003 Server for the deployed web app, however, on the VISTA SP1 machines after the build, I'm immediately getting a runtime exception thrown at FirstRequestInit on the HttpContext (every time).

Validating Web Site
(0): Build (web): Invalid access to memory location. (Exception from HRESULT: 0x800703E6)

The stack trace (bottom of this post) and indicators in VS2008 -- which is also installed on the XP workstations all targeting the 2.0 framework and work without problems -- state:

ASP.NET runtime error: Invalid access to memory location. (Exception from HRESULT: 0x800703E6)

I've installed fresh multiple times, adjusted configurations finally in IIS mutiple ways, checked and re-checked the permissions, etc., and this exception gets thrown every time, under every valid configuration under VISTA SP1 -- even with Cassini instead of IIS. I've tried it without the latest patches for v4.4 and with them, same issue.

Anyone else encounter this problem, or is it "my machine" specific? Suggestions, pointers?
