Due to contractual obligations to protect IP and client information, we unfortunately, cannot use Cloud or Mathematica Online for development in the development of our projects.
We are further required to use a source control system behind our firewall(s).
Are there any particularly good and recommended documents or white papers on application development in Mathematica?
Are there third party IDEs for Mathematica development (we did look at Workbench but it appears that it is still in development).
