Blazor
An experimental web UI framework using C#/Razor and HTML, running in the browser via WebAssembly
Blazor is a .NET web framework that runs in any browser. You author Blazor apps using C#/Razor and HTML.
Blazor uses only the latest web standards. No plugins or transpilation needed. It runs in the browser on a real .NET runtime (Mono) implemented in WebAssembly that executes normal .NET assemblies. It works in older browsers too by falling back to an asm.js based .NET runtime.
Blazor will have all the features of a modern web framework, including:
- A component model for building composable UI
- Routing
- Layouts
- Forms and validation
- Dependency injection
- JavaScript interop
- Live reloading in the browser during development
- Server-side rendering
- Full .NET debugging both in browsers and in the IDE
- Rich IntelliSense and tooling
- Ability to run on older (non-WebAssembly) browsers via asm.js
- Publishing and app size trimming
Note: Blazor is an experimental project. It's not (yet) a committed product. This is to allow time to fully investigate the technical issues associated with running .NET in the browser and to ensure we can build something that developers love and can be productive with. During this experimental phase, we expect to engage deeply with early Blazor adopters like you to hear your feedback and suggestions.
To see Blazor in action, check out Steve Sanderson's prototype demo at NDC Oslo last year. You can also try out a simple live Blazor app.
Getting Started
We are still very early in this project. There isn't yet anything you can download nor any project template you can use. Most of the planned features aren't implemented yet. Even the parts that are already implemented aren't yet optimized for minimal payload size. If you're keen, you can clone the repo, build it, and run the samples and tests.
Build
Prerequisites:
- .NET Core SDK (>2.1.4)
- Node.js (>8.3)
Run dotnet build Blazor.sln from the solution directory.
Run tests
Run dotnet test test/<dir>/<project>.Test.csproj
Run end-to-end tests
Prerequisites:
- Install selenium-standalone (requires Java 8 or later)
npm install -g selenium-standaloneselenium-standalone install
- Chrome
Run selenium-standalone start
Run dotnet test test\Microsoft.AspNetCore.Blazor.E2ETest\Microsoft.AspNetCore.Blazor.E2ETest.csproj
Run all tests
Install prerequisites for E2E tests
Run dotnet test test\AllTests.proj
Build VS Tooling
Prerequisites:
- Visual Studio 2017 15.6 (or newer)
- Visual Studio extension development features (install via Visual Studio Installer)
Open a VS Developer Command Prompt
Run the following instructions from the solution directory.
msbuild BlazorTooling.sln /t:Restore
msbuild BlazorTooling.sln
Use VS Tooling
To install the Tooling following prerequisites must be installed first:
