Editor enhancements

The Visual Studio for Mac editor has support for completion, IntelliSense and colorization schemes for .razor files. The colorization schemes are created resemble more with the Windows Visual Studio 2019 experience. Also preview boxes are there for any code changes that you do for code analysis fixes or bug fixes.

ASP.NET Core Blazor Server applications development and publish support

Based on the feedback, support is also added for development of ASP.NET Core Blazor Server applications. The Blazor framework is for creating client-facing web UI design using .NET and includes the following features

  • App logic sharing across client server
  • Development using a set of common and easy-to-use feature-rich languages, tools and frameworks
  • Writing interactive web UI designs using C# instead of the JavaScript library
  • Use of existing .NET libraries

Since it uses open web standards, Blazor requires no extra plug-ins hence whatever applications you develop they should work in all major current web browsers, desktop or devices.

You can create new Blazor Server as New Project > Blazor Server App project template

There is support for razor files with auto-complete and different color schemes in the editor. Also Blazor applications can be directly published to Azure App Service using Visual Studio for Mac provided you have a free Azure account.

ASP.NET Core Scaffolding enabled

One of the suggestions received by the Mac team was to add ASP.NET Core Scaffolding to Visual Studio for Mac. Hence now scaffolding for ASP.NET Core projects is also added in the mix. For those who are not aware, scaffolding helps in simplifying and speeding up ASP.NET Core application development by spawning a boilerplate code which is required for common tasks such as generating quick CRUD operation templates.

To access this feature follow
Project context menu > Add > New Scaffolding. The item on which you right-clicked will be the folder where the files will be generated and added.

Below is an example taken from the Microsoft website to show a wizard with steps for adding new scaffolding. This helps in generating CRUD code into our project. The example is ASP.NET Core samples project i.e. a movie database application which demonstrates how to enable scaffolding.

On clicking Finish, the required NuGet packages will be added to our project and files will be generated based on the scaffolding template that we chose.
