31st of May was a good day - Microsoft has released new RCes (release candidates) of their top products:

To be precise, numerous different technologies are being released together with those two, including (but not limited to):
  1. .NET Framework 4.5
  2. ASP.NET MVC 4 RC
  3. EF 5 RC
This version of Visual Studio is shipping with so-called "Go Live" license - it can be used to build apps that will run in product environments. It still may be risky to use it, but it’s close to RTM enough for a serious use.
When can we expect the final version? As MTS (Microsoft Technology Summit) has been postponed to mid-October due to new Microsoft products’ release, I suppose we can expect both Win8 and VS2012 released in September or early October.
Bon apettit.
