how we might change our Project Refs to File Refs, and not lose the benefit of the two points described above.

I guess my main struggle is how would I setup a pre-build script (or something) to figure out which file references are actually from projects I've got on my box, and then figure out if it needs to rebuild them, and them build them and copy the dll and pdb file over.

1. Try hard-coding the path to the default exe location
2. Try doing #1, but do it after the commit stage
3. If neither 1 nor 2 worked, then simply write a console app that instantiates your exe.
   If you cannot do this, then post a question here on how to do so

Step 1: get your executable to run AFTER it is completely installed by hand-
        starting a separate application which loads your app via hard-coded paths
Step 2: modify your code from step 1 so that it runs automatically AFTER the commit phase of the installer
Step 3: modify your code from step 2 so that it runs automatically PRIOR to the commit phase of the installer
Step 4: change the path to your executable so that it is NOT hard coded
