Customer Impact
This is a customer reported issue - #76350. The leak was introduced in .NET Core 3.1 and has gone unreported since then. This is specifically for the
IReflectscenario, which is mostly related to classIDispatchCOM interop scenarios.Although this impacts previous .NET runtimes, the OP has created a workaround and is not specifically asking for fixes prior to .NET 7.
Testing
Manually validated the user scenario and made the surrounding code easier to reason about. Validation was done using the Visual Studio Diagnostic tools for memory allocations.
Risk
Limited. This is for a relatively uncommon .NET Core scenario. The issue has existed since .NET Core 3.1 without being reported and the fix is scoped to only impact that particular scenario.
