In such cases, simply the defined order in the DBProviderFactories
configuration could take effect.
Or define custom configuration sections for DBLinq itself to determine
preferred vendor types in order.
An alternative solution is to create a static class to define
the preferred order of vendors (something like
DBLinqConfiguration.PreferredVendors). It could be combined
with configuration settings, and it won't suck for those who
don't like configuration settings.
Though I have to say I do not love my idea. It is sort of hack ;)
