Updated (2017):<\/strong> See\u00a0.NET Framework Releases<\/strong><\/a> to learn about newer releases.<\/p>\n

Today, we are announcing updates to the .NET Framework vNext, ASP.NET vNext and .NET Native. These are all available in Visual Studio \u201c14\u201d CTP4<\/a>. 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<\/a> with Visual Studio \u201c14\u201d CTP4<\/a> and give us feedback.<\/p>\n

.NET Framework vNext<\/h2>\n

Today\u2019s release of .NET Framework vNext adds RyuJIT<\/a> and ~ 150 new APIs. We have released multiple standalone versions of RyuJIT, after introducing you to it almost exactly one year ago<\/a>. RyuJIT is the new Just-In-Time (JIT) compiler, now integrated into the .NET Framework and enabled by default for 64-bit processes.<\/p>\n

We\u2019ve added ~150 new APIs across the product to make many scenarios easier. We\u2019ve 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.<\/p>\n

You can see the changes in this diff from the .NET Framework 4.5.2 to .NET Framework 4.5.3<\/a>.<\/p>\n

You may be wondering when we\u2019ll ship a separate redistributable for the .NET Framework vNext, like we\u2019ve had for all other .NET Framework versions. We haven\u2019t forgotten about it. It\u2019s still coming.<\/p>\n

ASP.NET vNext<\/h2>\n

ASP.NET vNext is a major update to MVC, WebAPI and SignalR, and runs on Windows, Mac and Linux. CTP4 includes a large set of updates since the earlier CTP3 release. You can learn about the updates to the ASP.NET vNext runtime and libraries in the release notes<\/a> on GitHub and the Visual Studio experience in the ASP.NET vNext in Visual Studio \u201c14\u201d CTP 4<\/a> blog post. The best place to learn more about ASP.Next vNext is from the links above, however, the highlights are covered below.<\/p>\n
