Microsoft announced the TypeScript 3.7 beta, introducing new features and bug fixes. 

The new features include optional chaining, which allows users to write code where they can immediately stop running some expressions if they run into a ‘null’ or ‘undefined.’ It also introduces nullish coalescing, which can be thought of as the ‘??’ operator – a way to “fall back” to a default value when dealing with ‘null’ or ‘undefined,’ according to Microsoft. 

The updated beta also includes assertion functions, Better Support for never-Returning Functions, more recursive type aliases. The full list of new features is available here.

.NET Core Windows Forms Designer Preview 1 now available
Microsoft introduced the .NET Core Windows Forms Designer Preview 1 following its recent release of .NET Core 3.0. 

The company said that the new .NET Core Windows Forms Designer will look and feel similar to the one for .NET Framework. Many controls are not yet supported in Preview 1 of the designer. 

“For us it is a huge technical challenge to bring the designer to .NET Core because it requires the design surface that hosts the live .NET Core form to run outside the Visual Studio process. That means we need to re-architect the way the designer surface “communicates” with Visual Studio,” Microsoft wrote in a post. “You can watch these communications in the Output Window, where we track each request sent when the Visual Studio components are accessing properties or executing methods on the live controls in the design surface.”
