How can I debug a 32-bits WCF service on a 64-bits machine?

I have a WCF service that depends on 32-bit DLLs, and as such it needs to run in 32-bits mode. However, on a 64-bits Windows 7 machine, Visual Studio 2010 starts WcfServiceHost.exe in 64-bits, and when it tries to load my service, it throws a BadImageFormatException.

Unfortunately, WcfServiceHost.exe will always run 64bit on a 64bit system. You can explicitly modify it to run in 32bit, but this is a fairly harsh workaround.

I typically will write my own hosting application, and use it to debug the service directly instead of using WcfServiceHost if you need to control the runtime mode.
