Tagging subscribers to this area: @thaystg Issue DetailsIt was passing id = 0 and asserting on mono runtime when trying to evaluate something in a Class that has the assembly loaded, but doesn't have any breakpoint added.

would it make sense to throw here if debugId <= 0?

Do you mean after GetAssemblyId?

I will do it, but in my backport version of this PR I will not add the throw to avoid any side effect on net6, does it make sense?

Okay, I changed my mind, I don't think we will get any side effect on net 6, because this is called from FindStaticTypeId and this has a try catch in the caller.

Should this throw if debugId != -1 && debugId != id to avoid reseting the id by mistake?

I don't like the idea to throw an exception but I added an if to set only if (debugId <= 0 && debugId != id)

ideas: Maybe add another test that tries to test the same thing, but by enumerating members of a local, or a field?
And maybe one where a previous frame is in that other assembly, and then check members on that frame?
