.NET Framework Blog - Announcing October 2014 Updates to .NET Framework vNext, ASP.NET vNext and .NET Native in Visual Studio “14” CTP4
Today, we are announcing updates to the .NET Framework vNext, ASP.NET vNext and .NET Native. These are all available in Visual Studio “14” CTP4. This .NET Framework release contains RyuJIT, the next generation X64 JIT. ASP.NET vNext contains major improvements in the runtime and Visual Studio Experience. Additionally, .NET Native contains a small set of fixes for reported issues. Please download these .NET releases with Visual Studio “14” CTP4 and give us feedback.
.NET Framework vNext
Today’s release of .NET Framework vNext adds RyuJIT and ~ 150 new APIs. We have released multiple standalone versions of RyuJIT, after introducing you to it almost exactly one year ago. RyuJIT is the new Just-In-Time (JIT) compiler, now integrated into the .NET Framework and enabled by default for 64-bit processes.
We’ve added ~150 new APIs across the product to make many scenarios easier. We’ve also updated ~50 more APIs (mostly types). In particular, we sprinkled IReadOnlyCollection<T> in more parts of the Framework libraries to make collections easier and more intuitive to use.
You can see the changes in this diff from the .NET Framework 4.5.2 to .NET Framework 4.5.3.
You may be wondering when we’ll ship a separate redistributable for the .NET Framework vNext, like we’ve had for all other .NET Framework versions. We haven’t forgotten about it. It’s still coming.
I blogged about this in August, .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... ?), but this is the first time I think I've seen an official'ish post giving it a version number, 4.5.3...
Now, we're still a ways from RTW, but the picture appears to be getting a little clearer...
BTW, the mentioned Diff spreadsheet is interesting (if you find that find of stuff interesting at least). Here's a snap of it.
