Version pinning. MSDN has some help on this. Basically you can pin down a version you don't want to change then promote the pin when you want changes to roll forward. How you implement pinning depends on whether your projects are branched or shared. From what you have said it sounds like you are sharing your code between projects. So, in your case you would want to pin your dev project to the last known good version. Normally we would pin production and test.
