Cannot start debugging on the web server. The connected connection was closed: the connection unexpectedly closed

Question

So, I turned off a whole bunch of "unnecessary" Windows services, and then I ran into: "Cannot start debugging on the web server. The main connection was closed: the connection was unexpectedly closed." error.

I think this particular error is slightly different from the typical “Unable to start debugging on the web server”, I found very few hits on Google.

In any case, it turns out that debugging depends on the COM + Event Service window service.

Just FYI.
