In this video Anders Hejlsberg spends some time discussing TypeScript. He starts with the reasons behind creating TypeScript (the so called elevator speech) and then moves on to some of the features coming in the next release. He mentions a number of features but spends the time discussing the null (and corresponding undefined) types and how TypeScript 2 makes handling them much easier.

app.Use(async (ctx, next) =>

//Re-execute the request so the user gets the error page
string originalPath = ctx.Request.Path.Value;
ctx.Items["originalPath"] = originalPath;
ctx.Request.Path = "/error/404";

LINQPad Succinctly offers IT professionals a detailed examination of how and why LINQPad can improve development lifecycle and deliver applications in less time. Author José Roberto Olivas Mendoza begins with a detailed overview of LINQPad's features, then delves into the installation process, including necessary prerequisites. Readers then get instruction on how to get the most out of LINQPad, such as how to query data bases and using LINQPad as a code scratchpad, which allows users to save significant time and effort on application delivery.
Cloud Computing is currently the hot topic in the developer world these days, and it seems all anyone wants to talk about is the cloud. If you're like me you signed up for something like Windows Azure just to see what the hype was all about. There are a lot of good reasons to move an app to the cloud, but it's still not for everyone. There are some things you need to think about before taking this gamble with your app.
Issues Fixed in this Release
Xamarin app throws Cannot access a disposed object. Object name: 'MobileAuthenticatedStream'error.
Xamarin.Android app throws ClassNotFoundException when deriving from Application class.
Upgrading may cause previously installed Windows and Android SDKs to be uninstalled.
Bumped JDK 8 to the latest version to avoid download failures from Oracle website.
My last post investigated ways to build a .NET Core desktop/console app with a web-rendered UI without bringing in the full weight of Electron. This seems to have interested a lot of people, so I decided to upgrade it to newer technologies and add cross-platform support.
The result is a little NuGet package called WebWindow that you can add to any .NET Core console app. It can open a native OS window (Windows/Mac/Linux) containing web-based UI, without your app having to bundle either Node or Chromium.
thanks to a new feature added in Visual Studio 2019 16.1, we can combine the best of both worlds when it comes to support the App Installer technology: the easiness of automatically generating an .appinstaller file as part of the package creation process and the flexibility of the new update features added in Windows 10 1903.
