AppDomain.CurrentDomain.BaseDirectory. This should be your deployment root directory, but if the exception message above is correct, it isn't being searched at all. Can you confirm that? Is the exception message exactly as shown above? If possible, try catching the exception in code to see its exact message.AppDomain.CurrentDomain.RelativeSearchPath. It looks like there might be a ClearScript bug here (it doesn't combine these paths with the deployment root path), but that shouldn't affect your scenario. Again, please verify the correctness and completeness of the exception message.Is there anything I could try changing in the Clearscript project, recompiling, and then redploy my Azure service?
