Azure Visual Programming Language?
Microsoft Visual Programming Language (VPL), was part of MS Robotics Studio and was used to visually program and compose DSS services. I think it is time to have a similar product on Azure for visually programming cloud services such as services deployed on Service Fabric. It has to be totally web based so users can run it in their browsers to connect services together and compose them into new services, all by drag-and-drop and drawing visual flows.
