Cannot find the assembly Microsoft.BizTalk.Pipeline.Com­ponents

The error message given usually is an incorrect error message. When I received this error message it was due to a spelling mistake in the namespace when I manually created the data and then tried to submit to BizTalk. To get the correct error, install the Microsoft.Pipeline.Components.dll into the GAC again. There is no need to uninstall the component. Restart the BizTalk services after GACing the component. Rerun the process.
