ASMX + external dll

I am working on Silverlight client to Microsoft Team Foundation Server. I am using an ASMX web service to make the actual calls using the TFS api.

Everything works fine when I run it with the visual studio development server, but I cannot figure out how to deploy the app to IIS.

I can get the ASMX web service to work unless it is a call that uses the TFS api. I have tried putting all of the TFS api DLLs in like every directory that I can think of, and even installing the visual studio sdk. Nothing works!

UPDATE 11/15/09 7:50PM EST:

Turns out that the TFS api was trying to create a cache at c:\Documents and Settings\Default User\Local Settings\Application Data\Microsoft\Team Foundation\2.0\Cache\, and the IIS_WPG user didn't have access to do so. Easy fix.

The only supported way of installing the TFS API is to install Team Explorer. You could try to GAC just the assemblies you need, but you're on your own [and technically violating the EULA]...

Other things to check:

IIS is running in 32 bit mode
Impersonation is working correctly
Proxy settings

What error do you get? Have you tried attaching a debugger to IIS?

IIS is running in 32 bit. Verified proxy and firewall settings to not be the cause. Could you elaborate on impersonation? That is something I am unfamiliar with. We have yet to attach a debugger to IIS, what should I be looking for with that?

Your service needs to use impersonation so that the user's credentials are forwarded to TFS. Otherwise TFS will complain that it doesn't know who [your IIS service account] is. Attaching a debugger is the easiest way to find which line of code is throwing an exception + what the state of your internal variables are at the time.
