LNK2019 for GetThisClass in 2003 to 2005 migration

I have looked all over and cannot find anything that seems related to this problem.  I know it is related to MFC, but it it beyond me how to fix it.
I have checked that _AFXDLL is defined, so the macros should be correct.  This the MFC code that is compiled: <font size=2>
m_pSessionDocTemplate = </font><font color="#0000ff" size=2>new</font><font size=2> CMultiDocTemplate(IDR_SESSIONTYPE,
RUNTIME_CLASS(CSessionDoc),
RUNTIME_CLASS(CMultiViewFrame), </font><font color="#008000" size=2>// custom MDI child frame </font><font size=2>
RUNTIME_CLASS(CSessionView));
m_pSessionDocTemplate->SetServerInfo(IDR_SESSIONTYPE_SRVR_EMB,
IDR_SESSIONTYPE_SRVR_IP,
RUNTIME_CLASS(CSessionIPFrame));
These are the link errors: </font>
