Adding live reloads developing Asp.Net Mvc Core razor views

To add live reloading when developing Asp.Net Core Views, it is recommended to upgrade to .Net Core 3.1. This makes it easier to add in the Nuget package for recompilation. In case you have a .Net Core 2 app, follow the MSDN guide here: https://docs.microsoft.com/en-us/aspnet/core/migration/22-to-30?view=aspnetcore-3.1&tabs=visual-studio After the app runs as .Net Core 3.1, run the following (procedure below is tested okay with VS 2019 and Chrome as the browser 'linked' to the reloading: Edit the .csproj file by selecting the project and right clicking and selecting Edit project file in VS 2019. Past in these two Nuget package references and run dotnet restore, then dotnet build and finally dotnet run.

  <ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation" Version="3.1.5" />
    <PackageReference Include="Microsoft.VisualStudio.Web.BrowserLink" Version="2.2.0" />
  </ItemGroup>

The runtime compilation and Browserlink should both be added. The first will rebuild your edited razor views (cshtml) and BrowserLink reloads your browser while debugging, after the razor view is updated. Also download this Visual Studio Extension, "Browser reload on save": https://marketplace.visualstudio.com/items?itemName=MadsKristensen.BrowserReloadonSave You will have to close all Visual Studio processes to start installing Mad Kristensen's browser extension. In your Startup class you should inside ConfigureServices add these two lines, specifying AddRazorRunitmeCompilation:

        services.AddRazorPages().AddRazorRuntimeCompilation();
        services.AddControllersWithViews().AddRazorRuntimeCompilation();

And finally at the top of the Configure method in the Startup class add in BrowserLink. Note, add this at the top of the Configure method such that the pipeline is adding BrowserLink correct.

  if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
                app.UseBrowserLink();
            }

Now, just start up your app with F5 and start editing a razor file. If all was set up correct, you should now see your razor view reload in the Browser. This makes it easier to edit and adjust razor views!
