Facebook announces React Fiber, a rewrite of its React framework 

C# 7 is a major update with a lot of interesting new capabilities. And while there are plenty of articles on what you can do with it, there aren't quite as many on what you should do with it. Using the principles found in the .NET Framework Design Guidelines, we're going to take a first pass at laying down strategies for getting the most from these new features.

Have you ever written a library in JavaScript or TypeScript? Are you planning to do it? If so, you must try Typescript library starter, a starter kit that will make easy to get started while providing all features you know to write a library in Typescript. 

Reactide is the first dedicated IDE for React web application development. 

The .NET Framework 4.7 includes improvements in several areas:

1. High DPI support for Windows Forms applications on Windows 10
   
2. Touch support for WPF applications on Windows 10
   
3. Enhanced cryptography support
   
4. Performance and reliability improvements 
   

As promised , we announced the open sourcing of MSTest Test Framework “MSTest V2”. The community now has a fully supported, open source, cross-platform implementation of the MSTest V2 portfolio with which to write tests targeting .NET Framework, .NET Core and ASP.NET Core on Windows, Linux, and Mac. 

If you stumble into this with no idea who I am or why I’m arrogant enough to think I’m qualified to potentially criticize the ASP.Net Core internals, I’m the primary author of both StructureMap (the IoC container) and an alternative “previous generation” OSS web development framework called FubuMVC that tackled a lot of the same problems that ASP.Net Core addresses now that were not part of older ASP.Net MVC or Web API.

Microsoft has come a long way in its effort to initially warm up to and later adopt open source software — from small skunkworks projects to full-fledged adoption and now supporting more than 10,000 engineers contributing to open source.
