This guide will step you through the process of enabling Browser Link in ASP.NET Core project.

Browser Link is a Visual Studio feature that helps you develop web apps in several browsers at once. If you using this feature you don’t have to rebuild your project and rerun browser to see changes that you made in views.

Under the hood Browser Link uses SignalR to create a communication channel between the browser and VS. Visual Studio acts as a SignalR server and browsers are clients and can connect to VS at the same time. When Browser Link is enabled it will register a middleware in the ASP.NET Core request pipeline. This middleware injects script into every page request dynamically.

1) Install the Microsoft.VisualStudio.Web.BrowserLink Nuget package

PM> Install-Package Microsoft.VisualStudio.Web.BrowserLink

2) Install the Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation Nuget package

PM> Install-Package Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation

3) Update the project’s Startup.ConfigureServices method to include a call to AddRazorRuntimeCompilation.

public void ConfigureServices(IServiceCollection services)

4) Call UseBrowserLink in the Startup.Configure method:

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
   if (env.IsDevelopment())
   // code deleted for brevity

5) Select browsers from the following menu and run your project. Select browsers

Now you can start using Browser Link in your project.
