Problem

We migrate a rather large BizTalk solution from BizTalk 2009 to BizTalk 2016. As far as I know, the mapping implementation changed in BizTalk 2013 to use the XslCompiledTransform (instead of the obsolete XslTransform).

My map in question compiles just fine but running it in BizTalk just leaves me with a suspended instance and an unhelpful error description:

Exception from HRESULT: 0x80131942

Root Cause

This is caused by a scripting functoid containing inline C#. The inline code contains a non-public method. This is no longer supported with XslCompiledTransform.

Solution

If you know the root cause, you probably know to fix it as well.

I had basically this in my scripting functoid inline c#:

1
2
3
4

string MySample(string param1, string param2)
{
    return param1+param2;
}

Changing it to the following fixes the error. Notice the public!

1
2
3
4

public string MySample(string param1, string param2)
{
    return param1+param2;
}
