- The button for switching the Solution Explorer view will now consistently show you a dropdown menu of all possible views.
Solution view switching
- Improved the loading time for very large solutions. The improvement varies based on the size of the solutions.
- Removed the Convert dialog under File > Convert. This feature was previously deprecated in Visual Studio 2015.
- Updated the validation rules for the task.vs.json and launch.vs.json schemas, and added descriptions for the properties.
- Added support for Linux remote debugging using a custom program via launch.vs.json.
- Visual Studio Search will now display on focus the three most recently used actions invoked through Visual Studio Search, as shown in this sample mockup. (Note: icons and specific line items have not been fully updated in this mock-up.)
- There is now experimental intellisense completion for unimported types! You now receive intellisense suggestions for types in dependencies in your project even if you have not yet added the import statement to your file. You must turn this option on in Tools > Options > Text Editor > C# > Intellisense.

- You can now use one-click code cleanup for projects and solutions. You can right-click on projects or the solution in the Solution Explorer and select ‘Run Code Cleanup’.

You will see a dialog box while cleanup is applied to each file
- You can now use a refactoring dialog to move type to namespace or folder. Place your cursor in the class name and type (Ctrl + .) to open the quick actions and refactorings menu and select ‘Move to namespace.’ This launches a dialog where you can select the target namespace you would like to move the type to.

- The codefix to add a private field from a constructor and vice versa is easier to discover and will show when any portion of the field name is selected. This refactoring now also offers all possible constructors.
XAML Designer Preview for .NET Core 3.0 WPF development
- There is an early preview of the XAML Designer for developers building .NET Core 3.0 WPF applications in Visual Studio. Many design-time features will be unavailable at this time. Since this is an early preview, if you encounter issues such as crashes, please submit Visual Studio feedback for the team to improve the experience going forwards.
- With each update to Visual Studio 2019, we will continue implementing more of the features that were previously available in the XAML Designer for .NET Framework WPF applications.
- We have updated the default Android Experience to API 28 for templates, device creation, installers, and more.
- IntelliSense on Windows now shows recommendations for design-time attributes when writing Xamarin.Forms XAML.
Changes related to Xamarin
As we have seen, there are 2 main changes. The first one is relative to Android, now everything is updated to API 28, so we should find updated Android templates.
The second change is relative to IntelliSense, now it should give us better recommendations when we write our Xamarin.Froms XAML files.
A very annoying bug has been fixed in Xamarin.iOS: Xamarin.iOS cannot find the application manifest. Please ensure the project contains a manifest file named ‘Info.plist”.
That was quite a bad bug and the only way to resolve it was to unload and reload the iOS project. Fortunately now Microsoft has fixed it so…..Yeahhh!
Are you going to update Visual Studio? I’m doing it right now!
