Verifying it connected

Now that you've completed the steps to connect dnSpy to VTOL VR through the Mono debugger server, you can verify that it's working correctly.

Check for a solid red circle on your breakpoints - this indicates that the debugger is successfully attached and you can start setting breakpoints in both the game code and your mod code.
