Process csc.exe restarted ?

I'm seeing in a particular case a lot of events on Windows IIS machines with the message:

Process csc.exe restarted

CSC is the C# compiler, so something is going on. Not sure, but probably associated with app pool recycles/restarts. Has anyone had any close encounter with this CSC, or have any idea what it might be doing in production environments, or still, how to analyze it further with Dynatrace?

CSC is restarted each time it needs to compile a .NET DLL.
So it should happen often when the server has just been started, and sometimes when a new (not yet called) endpoint is triggered.

Hm... maybe this process should be actually ignored by Dynatrace. Have you talked about this in help chat?

It's quite helpful, as it is associated with slow response times that I see in certain environments. Just have to figure out why they are running 😉

Yes, I understand those cases, although I do not see them those often in the circumstances that you mention . This has been a mystery to me for some time...
