Today we are excited to announce the general availability of the Microsoft Build of OpenJDK, a new no-cost distribution of OpenJDK that is open source and available for free for anyone to deploy anywhere.  

Expected in March , Angular 3 will focus on improved tooling and a reduction in generated code, said Rob Wormald, of the Angular core team and a developer advocate at Google.  

a habit tracker app that is free to use on 6 platforms: Web browser, Windows, Linux, Android, iOS and macOS. Approximately 98% of the programming code is the same for all 6 platforms. There are 3 different projects that use the shared code: - a Blazor WASM project for the PWA - a MAUI Blazor project for Windows, Android, iOS and macOS - a Photino Blazor project for Linux 

Bringing the browser developer tools to Visual Studio Code

• No need to detect what kind of events are supported, Tap handles this for you
• Small distribution size of 1Kb
• Use fastest event types supported (majority of browsers has ~300ms delay between touch/pointer events and click). Every millisecond does really matter!

WebAssembly, or Wasm, is on its way to becoming the next big thing in software development, allowing us to develop more reusable code across programming stacks. It will also enable the deployment of smaller packages more securely. This talk will focus on the view of a .NET developer using WebAssembly in their projects, whether client-side, server-side, or plugins.

SQLite compiled to javascript

For the impatients, try the demo here: http://kripken.github.io/sql.js/examples/GUI  

sql.js is a port of SQLite to Webassembly, by compiling the SQLite C code with Emscripten. It uses a virtual database file stored in memory, and thus doesn't persist the changes made to the database. However, it allows you to import any existing sqlite file, and to export the created database as a javascript typed array.  

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.
