BizTalk Best Practices (Handling Large Projects)
1. Use common .snk (key file) on all development machines so that you can uniquely qualify an assembly across all machines.
2. If you have used any helper utility or external assembly then make a shared network drive and put the build of your assembly (.dll) in that. Other people can use them without making a build on their local machine.
3. Avoid use of parallel shapes wherever possible. Its helps you in fast debugging of orchestrations and also gives best performance (scenario based).
4. If your development is going on multiple machines then use one master development server where you can configure and run full solution. Always use binding file of this master server to deploy orchestrations on test server.
