We have a .net 6.0 server app and the MS docs don’t give absolute clarity on how to set up our gen 2 garbage collection so it doesn’t suspend all our application threads.

We’ve put this in our .csproj file:

<PropertyGroup>
    <ServerGarbageCollection>true</ServerGarbageCollection>
    <ConcurrentGarbageCollection>true</ConcurrentGarbageCollection>
</PropertyGroup>

We build with dotnet publish -c release -r win-x86 --self-contained false ... (rather than msbuild, for info) …

But it doesn’t seem to have any effect – we still get suspended threads periodically that correspond to GC.

The docs suggest setting an environment variable and also a runtime json file setting, but just wondering if anybody has the gospel, proven word on how to implement this in .net 6.0 (or upwards)?
