BizTalk Error “A Correlation Set Can Be initialized Only Once” : An alternative solution

So you bumped into this error while compiling your BizTalk project. The most obvious reason could be : You have a correlation set set initialized on more than one places by mistake.

Now here is the tricky part: What if you have initialized it only once but still you are getting this error. What could be wrong.

Here are the possible reason:
You are using a long running transaction loop (For example in the resume pattern : and have initialized this correlation set in there ONCE :-). You see, even thou it is initialized once at run time it may be called more than one time, thus explaining the error.

You need to define your correlation set in a non long running scope contained within your long running scope and that will fix the problem for you.

Let me know if you have questions.
