I ran into this one a while ago. I couldn't find any information about the error on the internet, so I tried the microsoft public newsgroups. Again, no help (although those newsgroups are a GREAT place for getting help...). Anyway, I found out, what the error was, and it can probably be found in google groups by now, but I thought I'd just share it here as well.

Basically, the problem was that BizTalk 2004 SP1 apparently has a bug. If you have a "Call Orchestration"-shape (or a "Start Orchestration"-shape) in your orchestration, and this shape is placed in some particular unreachable code, you get this error.

I had a decision shape in my orchestration, but I hadn't gotten around to deciding what the rule in the decision shape was going to be. So I entered "1 == 1" in order for the assembly to compile and then I could deploy it and test it for that branch of my decision shape. Then, I wanted to test the other branch, still not knowing what the final rule would be. So I modified the orchestration to have the rule to be "1 != 1" - but then I couldn't compile - weird, eh?

Below is my orchestration.

So, as you can see - no funny stuff. Another weird thing is, that I can compile just fine with my "Call Orchestration"-shape after a Terminate-shape. But that is unreachable code as well.

I don't know what is happening, but it sure is weird.

I hope this posting has helped some of you.

Thanks. I got the same unhelpful error when i compiled today. I wanted to add some shapes within an unreachable if as i didnt want the testers to reach there yet. i added 1==2 and i kept getting this error. Your blog helped. Another thing i tried was to create 2 int variables with values 1 and 2 and compared the variables and it did compile..
