.NET vNext doesn't currently look like it's side-by-side "5.x," instead it's an in-place update like a 4.5.+ (so maybe 4.6'ish... ?)
We recently heard that after Jan 12, 2016, only .NET 4.5.2 would be getting technical support and security updates (Using .NET 4, 4.5, 4.5.1? Only 4.5.2 will be receiving technical support and security updates after Jan 12, 2016 (so start your 4.5.2 planning/deployment...)). In that same post there was mention about .NET vNext.
Today, we hear a little more about it and how we can start working with it (Visual Studio 14 CTP 3, which was also released today). But in reading the post it currently looks like the base .NET Framework vNext might be a 4.5.x or 4.6 kind of release. Now it's REALLY early in the release cycle and we're only talking CTP and there's a ton of other non base framework stuff we're getting, so don't freak out. Also Microsoft has been pretty clear that the base framework that we've known and lived with in the past is not going to be the primary deployment vehicle anymore....
In any case, here's the clip that I'm talking about;
.NET Framework Blog - Try out the new releases: .NET Framework vNext, ASP.NET vNext, .NET Native and RyuJIT
Today, we are announcing updated versions of .NET Framework vNext, ASP.NET vNext, .NET Native and RyuJIT. You can try out these new releases by installing Visual Studio “14” CTP3. Please tell us what you think.
The .NET Framework vNext
We are releasing an early build of the .NET Framework vNext with Visual Studio CTP 3. This early release includes a relatively small number of changes beyond what we shipped in the .NET Framework 4.5.2. Today’s release includes a handful of bug fixes, including many for WPF.
.NET Framework vNext is currently only available via Visual Studio 14 CTP3. We will include a separate installer later in the year. The .NET Framework vNext is an in-place update on top of the .NET Framework 4 and later versions. [GD: Emphasis added] It is supported on Windows Vista SP2, Windows Server 2008 SP2 and later versions. It does not yet have a “Go Live” license, so is not yet supported in production.
RyuJIT – Next Generation JIT Compiler...
The in-place update makes it sound like the 4.5.1,4.5.2 kind of update... That it's not a stand alone, side-by-side kind of release we saw with 4, 4.5. Not sure if that's good or bad, and I can see both sides of that, but it is interesting as in my mind I was thinking we were about due for a new base, a side-by-side 5.x .Net. Looks like that's not the case.
Will be keeping an eye on this as the release progresses...
