However, I question whether there is enough of a market for these services to be truly successful. There are plenty of .NET developers using Git - but for the most part many of them are just now getting to Subversion - or even worse going with TFS (Microsoft's mess of a SCM). MS developers are also traditionally inside medium to large companies - the majority of which want their applications hosted in their own data centers. MS might be able to convince them to use Azure - but a small startup is going to have one helluva time convincing them to host their LOB app with them.
