notpattern matching syntax when a suppression operator is present- Inline method refactoring to help replace usages of static, instance, and extension method within a single statement body

inkeyword where the argument should not be passed by reference- Refactoring that introduces the new C#9 pattern combinators and pattern matching suggestions such as converting
==to useiswhere applicable- Code fix to make a class abstract when you are trying to write an abstract method in a class that is not abstract
- IntelliSense completion in DateTime and TimeSpan string literals automatically appear when the first quote is typed
- Code fix to remove unnecessary
pragma suppressionsand unnecessarySuppressMessageAttributesRenameandFind All Referencesunderstands references to symbols within the target string of globalSuppressMessageAttributes- ByVal fades to say it's not necessary along with a code fix to remove the unnecessary ByVal in Visual Basic
- Interactive window support for multiple runtimes, such as .NET Framework and .NET Core.

JavaScript/TypeScript:
- XAML Binding Failures diagnostic improvements
- XAML Hot Reload Settings moved to "Debugging > Hot Reload"
- Toolbox population from unreferenced NuGet packages
- The JavaScript/TypeScript debugger now supports debugging service workers, web workers, iFrames, and your page JavaScript all at the same time! In addition, the new debugging experience adds support for debugging your back-end node server applications and client-side JavaScript in the browser simultaneously. This feature is still experimental. You can enable the new debugging experience in the Debugging options menu
- You can now trigger refactors anywhere they might be available by using the code action shortcut (ctrl + .). You don't even need to select any text - TypeScript is now smart enough to look around your cursor location for the best available refactors!
- You can now fine tune which packages TypeScript searches for automatic import completion. This can lead to performance improvements in some projects with a lot of dependencies. For more details, please reference the TypeScript 4.0 (release notes)[https://www.typescriptlang.org/docs/handbook/release-notes/typescript-4-0.html]
- We added a message in the output pane showing which types we install to support intellisense. We recommend adding a tsconfig to your project to customize which types are used.
- Please note we include the TypeScript 4.0 compiler and language service
