In this session, learn why the Angular team uses Typescript to develop at scale inside Google, and how Typescript and Angular work together to provide a powerful platform for your developers and great experiences for your users.
At least 80% of all information being collected by enterprises includes geolocation data. The Bing Maps V8 library is a very large collection of JavaScript code that allows web developers to place a map on a webpage, query for data, and manipulate objects on a map, creating a geo-application. In Bing Maps V8 Succinctly, James McCaffrey takes readers through utilizing this library, from creating the simplest application that uses it, to mastering more advanced functions like creating color-gradient legends and custom-styled Infobox objects.

Have you ever found a bug in your code and wanted to pause code execution to inspect the problem? If you are a developer, there’s a strong chance you have experienced or will experience this issue many, many times. While the short and sweet answer to this problem is to use a breakpoint, the longer answer is that Visual Studio actually provides multiple kinds of breakpoints and methods that let you pause your code depending on the context! Based on the different scenarios you may experience while debugging, here are some of the various ways to pause your code and set or manage a breakpoint in Visual Studio 2017

In the February 2016 issue of MSDN Magazine, I showed how to create a custom scripting language based on the Split-And-Merge algorithm for parsing mathematical expressions in C# (msdn.com/magazine/mt632273). I called my language Customizable Scripting in C#, or CSCS. Recently, I published an E-book that provided more details about creating a custom language (bit.ly/2yijCod). Creating your own scripting language might not initially seem to be particularly useful, even though there are some interesting applications of it (for example, game cheating). I also found some applications in Unity programming.
