LabVIEW 2026Q1 still has the .NET Core memory leak

[Cloedu72]

I already detected the memory leak in LabVIEW (32bit) version 2025Q3 and opened a ticket. I received confirmation (via R&D) that the problem should be fixed in the official LV2026Q1 version.

Sorry NI, the problem still exists and could have been tested with my super simple VI. I don't know what else to say to our customers about this. Will it perhaps be fixed next year?

This is about trust and reliable systems. I don't see either of those at the moment.

Yeah, I see this as a big concern... Makes it tough to use this feature in production 😞

[alexderjuengere]

do you also see this kind of conduct with labview 64 bit and .net 64 bit, or is this due to the 32 bit versions?

[Cloedu72]

I have only tested it with 32-bit.

[jyoung8711]

I can confirm that this is still a bug for 64-bit as well -- tested with this example

Apologies for the inconvenience caused, we will shortly provide a patch for this issue in LV2026.
