Still Limited x64 support in TFS 2008


Hi, well I’ve been installing Team Foundation Server 2008 and I’m still amazed that the TFS Application tier won’t run on 64 bit processors.

From the official TFS help documentation:

"You can install some, but not all, Team Foundation components on these 64-bit operating systems. Visual Studio Team System Team Foundation Server supports running the Team Foundation data-tier and SQL Server on both 32-bit and 64-bit platforms. Team Foundation Server requires that the application tier components run in a 32-bit environment. The application tier does not support WOW64 or native 64-bit modes."

Looks like no one is taking WOW64 or native 64 bit environments very seriously.  How long do we have to wait?  I don’t want to run my data tier and app tiers separately. 

I’ve accomplished a quasi single tier by installing the App tier in a 32 bit virtual machine using Virtual Server (64) on Windows 2003 Server R2 (64 bit edition) and installing the data tier locally (native) with a 64 bit edition of SQL Server but I’d rather not go to those lengths, thank you..
