Managed code may not be executed if an InfoPath 2007 workflow form is deployed as a feature for a workflow

Consider the following scenario. A Microsoft Office InfoPath 2007 workflow form contains managed code. The form is deployed as a feature for a workflow. In this scenario, the managed code may not be executed.

This issue occurs because a compiled DLL becomes part of the InfoPath form template (XSN) file when you create managed code behind an InfoPath form. Microsoft Office Forms Services does not extract a DLL by expanding the XSN file when the XSN file is installed by using the features functionality.

To resolve this issue, copy the compiled DLL to the same folder to which your feature XSN file was deployed.
