Even though this is a very simple question, I cannot seem find a definitive authoritative answer to it.
All the sample code I have found is meant to run on Windows 8, but I remember having read somewhere that Media Foundation was included in Vista.
Are some features only available on Windows 8? or can I safely develop for Media Foundation (via SharpDX) knowing that it will run on a Windows 7 machine?
Most of the MediaFoundation API is backward compatible with Windows Vista/7. Though there are a couple of API introduced for Windows 8 (for example MediaEngine) that are not available in Windows 7. You can check if the API is accessible from Windows 7 at the botttom of each interface documentation on MediaFoundation msdn documentation.
