Here is a some additional information regarding extending BTARN 2010 with new PIP’s. The artifacts generated are going to be .Net 4.0 unless Visual Studio is configured to do otherwise. This means along with setting the application pools for the 32-bit the .Net setting must be set to match.
The error will happen after receiving a document using the new schema. Here is a sample error.
