Microsoft Open-Source and Cross Platform Development

.Net Framework - SeniorDBA

The Microsoft .Net framework has been around for about 14 years. While C#, C++, VB.NET, and F# seem to be the most supported and used languages to build .NET applications, there are close to 50 languages that are supported by the .NET framework.

In 2014, Microsoft moved to open-source .NET by introducing .NET Core. Most of the .NET components (compilers, languages, libraries, and tools) are now open-source and available in Github.

The new open-source component of .NET is named .NET Corevand has even more developers embracing what Microsoft is doing with .NET and the associated programming languages. Microsoft has acquired Xamarin and its products so developers can now use C# to build Android, iOS, and Windows mobile apps.

Is now the time to seriously consider the Microsoft .Net framework for your development?

.NET Framework 4.6.1

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.
