Hi,

I have a very simple C# application, and am starting a new process by specifying path of the executable.

its works well but some times what happens is new process starts and stays for sometime and closes but it is not hitting the Main method(I have kept some logs ).

I can see new process in Task manager.

Problem Ex:

1. Consider new process Name is "Example.exe"
2. I have added some logs in the Main method and some other places
3. When I start "Example.exe", It shows in Task Manager for sometime and closes.
4. But Logs are not getting created, Means it has not executed/Entered the Main method(It happens only some times)
5. It works well in most of the cases.

Can anybody gives me some hint, whats going wrong.

What I have tried:

I do not know exactly how to track whats happening while starting a new process

Impossible to help without to see your source code.

sounds not normal. Can't offer any help without seeing your "log-method" - Id guess - most likely there is something wrong with it (or the original call to the process). What could also be possible: If the process has an error in creating any static members (maybe you want to initialize some static members form configuration that is not present?), so maybe an exception is thrown BEFORE the Main method is executed.

Wrong. The Main method is ALWAYS called. The problem is the logs aren't being written for some reason.

Without seeing the code, it's impossible to tell you what you're doing wrong.

"The problem is the logs aren't being written for some reason"
I have checked this case also, No event logs and code also not executed at all.
I checked that scenario.

No, you haven't. As much as you say you have, you're missing stuff.

The Main method is ALWAYS called. It will NEVER be missed. The sole exception to this is if a virus scanner determines your executable isn't safe and quarentines it.

AGAIN, we can't see your code (because you haven't posted it!) so it's impossible to tell you what you're doing wrong.

Solution 1

Have a look at some of the debug tools available e.g. Windows Sysinternals - Windows Sysinternals | Microsoft Docs[^] - you might get some clues.

Another good place to look for clues - Windows Event Log (Windows)[^]
