Pull Request Overview

This PR removes an explicit call to GC.Collect() in the OutOfProcNode.cs file to prevent unnecessary manual garbage collection.

• Removed explicit GC.Collect() call
• Updated memory cleanup logic by relying on automatic garbage collection

[SimaTian]

With the branch update, it now reports correctly that the GC.Collect is already gone.
That being said, I will use this PR to remove the now redundant compiler directive as suggested in the conversation.
