The newly created cpp file through UE Editor does not appear in the solution in Rider, for it to appear, you need to close the IDE and re-open the cpp file. Only after the specified procedure, the files appear in the solution.

FInally, I founded fix for this problem. I just reinstall RiderLink plugin and it works! Now UE automatically see new files. My best day in development on UE4. [348914-settingsrider.png]
