Compiler code generators fail unexpectedly #20294

Open jcouv opened 7 years ago

jcouv commented 7 years ago

I was making a change to BoundNodes.xml. Initially, I had made a bad change, so the generator would fail on that (which is expected). But after sorting that part out, I still go an error generating C# syntax. Re-running the tool then passed that stage and failed on VB syntax. Re-running the tool succeeded.

FYI @jaredpar

Do you have the change to BoundNodes.xml that was causing the problem?

Yes I added an IsUsed field to deconstruction operator. But initially I had type as bool instead of Boolean. After I fixed that issue is when I got errors generating other files. But those errors disappeared without any further changes.
