64 bit - Is Visual Studio 2010 WebDev WebServer (Cassini) 64-bit compatible?

Question

I'm now developing on Visual Studio 2008 on a 64-bit OS (Windows Server 2008 64-bit).

While the apps I write are 64-bit capable, as is IIS7, the built-in ASP.NET Development Server (aka Cassini aka WebDev.Webserver.exe) runs as 32-bit.

This brings up a plethora of issues, such as:

• 32-bit and 64-bit applications have separate HKLMSoftware registry homes
• There are 32-bit and 64-bit versions of the SQL Server Client Network Utility
• Other fun surprises I haven't discovered but I'm sure will spring up

While I am finding workarounds for most of this, I have to ask...

Does anyone who has played with the Visual Studio 2010 preview bits on 64-bit architecture know if the development web servers can handle 64-bit, and if so, are there options for which mode to run it in? (Like a checkbox in the project properties, for instance)

Full source code for a direct replacement for VS2008/2010 dev servers is available at http://cassinidev.codeplex.com. You can compile to x64 to support your requirements.
