Hi,

I have added a function named 'UpdateGlobalCommitWithSundialTransactionId(System.String, System.String)' in a project. I call the same function from the Biztalk project. But when running Biztalk I get the following error

I see the following text in the error

Comment from Op:
ok. So the basic problem is that I'm unable to call any method defined in a project from the Biztalk orchestration. (biztalk project). Also there is nothing clear from the error to me as well as it does not specify which file is remaining to be referenced. (its just the Exception type: ReflectionTypeLoadExceptionSource)

When it says: "Retrieve the LoaderExceptions property for more information" what more information did it give?

Solution 2

Try debugging your code to narrow down your problem and then post here with some more details - this is too difficult to figure out.
