ASP.NET 3.5 32 bit or 64 bit

I'm build a website with ASP.NET 3.5 which uses legacy 32-bit COM components.  I'm developing on 64-bit Windows Vista.  Is it possible (and sensible) to set my website to be built as a 32-bit target.  I can't find any options in Visual Studio 2008 to set the platform target to 32-bit.

Also, do I need to setup ASP.NET to run under 32 bit? Microsoft's KB at http://support.microsoft.com/kb/894435/en-us does not cover Vista (I can't get those scripts to work under Vista)

When I build my project under 32-bit XP the website runs fine, however the site needs to dynamically create an Active X control (using .NET's AxHost) which works OK on the XP build but fails under 64-bit Vista.

Thanks in advance,

I ended up re-deploying this site on a 32-bit server and that worked correctly.  I am not sure why 3.5 does not work on 64-bit servers...

Redeploying on a 32-bit server is of course an option but I would be rather surprised if ASP.NET 3.5 did not support 64 bit whereas ASP.NET 2.0 did.

I found the solution to this was to disable DEP in Vista
