Just curious, does this use HMF or is it already on the asm helper plan under the hood?

There was a problem hiding this comment.
It doesn't use HMF since this must be called when an actual transition is performed - a QCall. The QCall erects a normal transition frame to unmanaged. Note that SuppressGCTransition on a QCall makes this call invalid. The COMPlusThrow APIs hook into the normal .NET exception mechanism here. I'm not the expert in this domain so if you need more details @jkotas or @janvorli are best to comment on how it aligns with the referenced approach/comment.
