Research direction

The reproducer is the attached TestQrApp.zip, which the issue links but does not describe, so start by unzipping it and running it under a .NET allocation profiler or with GC event counters to see which calls drive the gen0 collections. The payload names no library files or entry points, so locating the allocating code is the first real step. Done means identifying the allocation source and either reducing it or writing up usage guidance that explains the collection rate.

Written by the indexing model from the issue text.

Description

The current version of the package functions correctly during use, but it triggers high-frequency garbage collection (GC). Is there any way to improve this situation or any usage practices that could help avoid it?

The attachment contains a reproducible version of the program. Please refer to it.
