You're trying it in the experimental engine?

Russell D

Ah yes. Sorry my eyes just glossed over that.

Try it in the new engine:

Ok, I just updated to version 10.0.9.857 VSPro. Still no luck. I extracted the source of the latest (Edge) version of Dockers, "Docker for Windows.exe". This is the content of one of the files:

System.InvalidOperationException: Invalid expression stack size during null coalescing expression translation.

Getting the source for Docker.Core:

@Geedsen can I just confirm if you're doing this from within Visual Studio, and so are using the old translation engine? This isn't reproducible using the new engine so just wanted to rule that out.

If you're using Desktop can you try it in the new engine?

Geedsen

No, I am just running .net reflector. Sounds strange that with the same version of reflector and the same assembly we are trying to decompile we would get different results. Is there a dependency for reflector that I may have a different version of?

Geedsen

I don't think so, just version 10.0.9.857 VSPro. Does the text 'OldTranslator' in the errors tell me something about what is being used?

Geedsen

Indeed , the experimental engine works just fine. Thanks

Russell D

Great, thanks for confirming!
