Tune in online on December 4, 2018 for a full day of dev-focused delight—including updates on Azure and Visual Studio, keynotes, demos, and real-time coding with experts—live from the Microsoft Azure and AI Conference. 

Build Accelerator, BuildXL for short, is a build engine originally developed for large internal teams at Microsoft, and owned by the Tools for Software Engineers team, part of the Microsoft One Engineering System internal engineering group. Internally at Microsoft, BuildXL runs 30,000+ builds per day on monorepo codebases up to a half-terabyte in size with a half-million process executions per build, using distribution to thousands of datacenter machines and petabytes of source code, package, and build output caching. Thousands of developers use BuildXL on their desktops for faster builds even on mega-sized codebases.

ReSharper 2016.1.1. The update helps ReSharper see controllers outside of ASP.NET MVC areas and folders again (RSRP-458398, RSRP-455213); adds smart, license-aware update checks; enables bulk renaming in TypeScript (RSRP-458570); fixes Go to Everything so that it works after suspending and resuming ReSharper (RSRP-458404); improves performance in solutions with large JavaScript and JSON files (RSRP-458363); fixes pessimistic mode in value analysis (RSRP-458210); makes IL Viewer available via the Navigate To pop-up (RSRP-458323); improves details of ReactJS support (RSRP-458229, RSRP-458242, RSRP-458308). See all fixes in ReSharper 2016.1.1.  

Angular 1.3 might be the best Angular yet, but there's still lots of high impact work to be done on the 1.x branch. We still have Material Design, our new router, and improved internationalization of Angular apps still to come ... 

The Angular 1.x project needs someone to be fully committed to keeping v1 moving forward, and supporting the Angular ecosystem that has grown around it.

That's why I'm delighted that Pete Bacon Darwin has agreed to take over the leadership role for Angular v1.  

But Pete can't do this alone. He needs Brian, Caitlin, and Chirayu to help make v1 even more awesome. Jeff will help out with google3 sync and releases, and familiar faces like Matias Niemela and Pawel Kozlowski (who co-wrote one of the first books on Angular with Pete) will be ongoing contributors. We're also looking forward to meeting new faces. Over time, some of these folks will shift their focus towards Angular 2, but for the immediate future, what's most important is that Angular 1.x is and continues to be well taken care of.
