LabVIEW 2025Q3 .NET core memory leak!

[jyoung8711]

This is consistent even with built-in .NET functions.

See the attached VI where it's just generating some GUIDs.

It takes almost 2 orders of magnitude to run the .NET Core version.

You can see the memory drift as well if you have Process Manager open.

According to patch notes memory leak got already fixed with latest patch Bug Fixes 26Q1

There's another post about this where someone from R&D (I think) chimed in and said they thought it was fixed, and that they did some memory optimization... I think they missed the core issue though 😞 

The patch notes were not posted when I did my initial testing.
