>>Also, Michel Fournier, the owner/operator of the UT, found that the latest available VFP OLEDB provider is not reliable under load. After much back-and-forth with MS, that's another issue that will not be fixed. Arguably, this shouldn't be too much of a problem because OLEDB is being deprecated by MS. But, the situation with ODBC is even worse, the latest driver only supports VFP6, and none of the data/database changes made since then are supported.

>>MS is not so much actively trying to kill file-based databases, instead it's neglect and/or lack of testing. SMB3 is coming out in Windows 8/Server 2012, both are still in RC. I don't know if anyone has set up an environment with these OSs for testing but chances are the community is going to have to do it, because MS probably won't.

But please do not feed into all of this paranoia that there will be a problem with VFP (as refuted above by your initial references, no less). Microsoft is not trying to kill file-based dbfs and it is REALLY ridiculous to think so! Also, it is highly unlikely this will be a problem by accident since SO MANY would be adversely affected (not just foxpro!) - which MICROSOFT DOES CARE ABOUT.
