As well, it provides you the standard support you would expect such as building, running and debugging Blazor projects. In Visual Studio for Mac 8.6 support for creating, building and running Blazor WebAssembly projects was added.
In the walkthrough above, we saw how the Blazor Server App project template helps you create a new Blazor Server App project. Let's take a look at some of the additional features in Visual Studio for Mac to support Blazor project development.
Editor support for .razor files
Visual Studio for Mac includes support for editing .razor files - majority of the files that you’ll be using when creating Blazor applications. The Windows and Mac version of the IDE share the same editor for .razor files. You’ll see full colorization and completion support for your .razor files including completions for Razor components declared in the project.
Publishing Blazor applications to Azure App Service
You can also publish Blazor applications directly to Azure App Service. If you don’t have an Azure account to run your Blazor app on Azure, you can always sign up for a free one here that also comes 12 months of free popular services, $200 free Azure credits, and over 25 always free services.
Project anatomy
Blazor web apps include a few directories and files by default. As you're getting started, here are the main ones you'll need to be familiar with:
Pages folder
This folder contains a project's webpages, which use a .razor file extension.
Shared folder
This folder includes shared components, also using the .razor extension. You'll see that this includes MainLayout.razor, which is used to define common layout across the application. It also includes the shared NavMenu.razor component, which is used on all pages. If you're creating reusable components, they'll go in the Shared folder.
