Microsoft .NET 4.6.1 has been released. With the .NET Framework 4.6 and higher, you’ll enjoy better performance with the new 64-bit “RyuJIT” JIT and high DPI support for WPF and Windows Forms. ASP.NET provides HTTP/2 support when running on Windows 10 and has more async task-returning APIs. There are also major updates in Visual Studio 2015 for .NET developers, many of which are built on top of the new Roslyn compiler framework. The .NET languages — C# 6, F# 4, VB 14 — have been updated, too.
The Microsoft .NET Framework 4.6 and higher is highly compatible for in-place update to the Microsoft .NET Framework 4, the .NET Framework 4.5, the .NET Framework 4.5.1, and the .NET Framework 4.5.2.
Wherever possible, Microsoft recommends you use the Web Installer instead of the Offline Package for optimal efficiency and bandwidth requirements. The offline package can be used in situations where the web installer cannot be used because of a lack of Internet connectivity.
The .NET Framework 4.6.1 RC includes new features in the following areas:
- Windows Presentation Foundation (WPF)
- Windows Workflow Foundation
