fwiw, this did not help me at all 
Hi, try to select a solution configuration “Debug Game” in VS.
Looks like the current solutions don’t work anymore. Anyone else still haveing this issue with Rider?
Somehow I recently had to redo this change in the registry + reboot my machine, and all the modules were properly loading again in VS 
Just a small note that could help others: after you created the registry key, you must reboot the machine.
The Windows kernel read the key only on startup. This was explained in the Microsoft KB 953490: https://web.archive.org/web/20100121111745/http://support.microsoft.com/kb/953490
Oh, it’s work, thank very much
