I recently encountered a strange thing. On some of my company's servers when an exception message is printed out (yes, bad, I know. It's for debugging), the actual message isn't displayed. Instead it displays the key for an external string resource and says that "Debugging resource strings are unavailable"

After some research I've come up with the following:
In release mode, Silverlight does not package the xap with the dlls containing the actual error messages in order to save space.

I've found workarounds for OLD versions, but nothing for 4. It seems like there are Developer versions of the SL 2 and 3 runtime which will resolve the errors automatically, but I cannot find one for SL 4.

So my question is this:

**What the heck do I need to do to my SL 4 app / computer to let me see the full, detailed errors when it's in release mode?**
