Solution to BDC Import Error: “Could not load Type described by TypeDescriptor’s TypeName …”

I’ve been working with BDC today, coding ADF files by hand and generating myself some errors.  One such error:

Application definition import failed. The following error occurred: Could not load Type described by TypeDescriptor’s TypeName. Parameter name: typeName Error was encountered at or just before Line: ’35’ and Position: ’20’.

MOSS displayed this error when I tried to import the ADF XML file.

I researched the Internets and found that I was referencing the LOB instance name (from the <LobSystemInstance>) in my <TypeDescriptor> node when I should have referenced the LOB name itself (from <LobSystem>).

Wrong:

<TypeDescriptor TypeName="Conchango.KeyValue, LOB Instance Name" Name="KeyValue">

Correct:

<TypeDescriptor TypeName="Conchango.KeyValue, LOB Name" Name="KeyValue">

Hope this one saves someone an hour or two of time.
