VS Code Now Supports Blazor Development

Visual Studio Code now does Blazor development thanks to updated Razor tooling support in a C# extension.

Razor and Blazor are related as they're both part of ASP.NET Core, the Web-centric component of the .NET Core initiative that serves as a cross-platform, open source alternative to the ageing, Windows-only .NET Framework.

Razor is a syntax for combining HTML markup with C# code, according to Microsoft documentation, said to boost productivity while allowing developers to switch between markup and C# in the same file while enjoying IntelliSense support such as auto-completion.

Blazor is a Microsoft project that just graduated from the experimental stage with a way to leverage WebAssembly -- which is still experimental -- in order to do client-side and server-side Web development with C#.

Preview support for both of these is included in the C# for Visual Studio Code extension available in the Visual Studio Code Marketplace.

Last week, Microsoft announced an update to the extension that boosts Razor tooling support with improved diagnostics and tag helper support, along with giving developers auto-completion for components and component parameters, data binding, event handlers and more.

The improved Razor diagnostics, meanwhile, include pointing out errors concerning: floating @ characters; missing end braces; and missing end tags in code blocks.

The other main enhancement to Razor tooling support is auto-completion for tag helpers, along with tag helper attribute names and values.

Microsoft said the improved Razor tooling support for VS Code should be considered an alpha release, with known issues including:

Razor editing is currently only supported in ASP.NET Core and Blazor projects (no support for ASP.NET projects)
Limited support for colorization

More information about Razor tooling support in the VS Code C# extension can be found on the Razor.VSCode GitHub site. The C# extension is available in the VS Code Marketplace (more than 4 million installations), with source code available on GitHub in the C# for Visual Studio Code (powered by OmniSharp) project.

See this post for more information, including the prerequisite installations required to preview Razor support in VS Code -- along with those needed to work with Blazor -- in addition to feedback guidance and more.
