There is an issue with the Azure 1.6 SDK that I often hit when I run a cloud project. I get around 3-5 debug sessions with my cloud project before Visual Studio starts throwing an Invalid access to memory location error.
This issue seems like it is hitting many other people as well. This is a significant pain point for working with Azure projects and there is currently no suitable workaround or fix that I can find. Sometimes shutting down the emulator and trying again works. Most often however, the IDE needs to be recycled. Having to do this each fifth F5 is a productivity killer.
