One key thing that may help is standards on formatting. I know that sounds silly, but many merge issues result from developers hitting the source format button and create merge problems. If you keep things to format standards, it will help merging in future. Even lengthening lines to 132 instead of 80 may reduce confusion - another silly suggestion, but I have seen it help in a couple of places. Keep your interface classes and base classes stable. If you are changing those during development, you are going to impact the larger world and probably should set up a dedicated feature branch off of Development and have all topic branches involved in the API change branch off that one. Frequent merges into topic branches are common when API changes are ongoing (as are conflicts) - they should not be as much when the APIs are stable. If you can, get the API changes done first, then create topic branches after the API is stable. >From what I have seen, frequent conflicts are sometimes an indication of an underlying development process problem - you should look into this and see whether there are issues here. Conflicts happen, but the "why" is important to understand. Cheers, Randall
