To interact with .NET try the OLE DB strings,under Visual FoxPro at this site (not DBF/FoxPro). Or if you want to force ODBC you could use the third one under OLE DB and create a DSN. The older DBF/FoxPro OLEDBConnection (.NET) uses the Jet.OLEDB. From the Microsoft Visual FoxPro help file:
"The Visual FoxPro OLE DB Provider (VfpOleDB.dll) exposes OLE DB interfaces that you can use to access Visual FoxPro databases and tables from other programming languages and applications." Search Microsoft's website for the .dll. I think they offer it for download.
