> how do you [know] in advance if you got a MFC-like library from MS with 20+ year support vs a library like Sliverlight where they drop support and let you alone with a migration to a different platform ?

If it is old, it will be supported for a long time. If it is new, the odds are mostly on it not surviving. Ever wondered why so many people insist on using outdated stuff?

You get a better deal from open source. But even there you may not like the possible consequences of using non-mainstream things.
