Bootstrap

Note: Before continuing please make sure that you already have a Blazor project created. If not please go to the official Blazor site and learn how to create one.

Installations

1. NuGet packages

First step is to install a Bootstrap provider for Blazorise:

Install-Package Blazorise.Bootstrap

You also need to install the icon package:

Install-Package Blazorise.Icons.FontAwesome

2. Source files

The next step is to change your index.html or _Host.cshtml file and include the CSS and JS source files:

<!-- inside of head section -->
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap@4.6.0/dist/css/bootstrap.min.css" integrity="sha384-B0vP5xmATw1+K9KRQjQERJvTumQW0nPEzvF6L/Z6nronJ3oUOFUFpCjEUQouq2+l" crossorigin="anonymous">
<link rel="stylesheet" href="https://use.fontawesome.com/releases/v5.12.0/css/all.css">

<link href="_content/Blazorise/blazorise.css" rel="stylesheet" />
<link href="_content/Blazorise.Bootstrap/blazorise.bootstrap.css" rel="stylesheet" />

<!-- inside of body section and after the div/app tag  -->
<script src="https://code.jquery.com/jquery-3.5.1.slim.min.js" integrity="sha384-DfXdz2htPH0lsSSs5nCTpuj/zy4C+OGpamoFVy38MVBnE+IbbVYUew+OrCXaRkfj" crossorigin="anonymous"></script>
<script src="https://cdn.jsdelivr.net/npm/popper.js@1.16.1/dist/umd/popper.min.js" integrity="sha384-9/reFTGAW83EW2RDu2S0VKaIzap3H66lZH81PoYlFhbGU+6BZp6G7niu735Sk7lN" crossorigin="anonymous"></script>
<script src="https://cdn.jsdelivr.net/npm/bootstrap@4.6.0/dist/js/bootstrap.min.js" integrity="sha384-+YQ4JLhjyBLPDQt//I+STsc9iw4uQqACwlvpslubQzn4u2UU2UFM80nGisd026JF" crossorigin="anonymous"></script>

<script src="_content/Blazorise/blazorise.js"></script>
<script src="_content/Blazorise.Bootstrap/blazorise.bootstrap.js"></script>

Note: When Blazor project is created it will also include it’s own Bootstrap and FontAwesome files that can sometime be of older versions. To ensure we’re using the appropriate bootstrap and FontAwesome files, you need remove them or replace them with the links from above. If you forget to remove them it’s possible that some components will not work as expected.

3. Using’s

In your main _Imports.razor add:

@using Blazorise

4. Registrations

Starting from .Net Core 3.2 there was some changes regarding the setup process for Blazor WebAssembly project types. Specifically the Startup.cs file is removed and all registrations are now done in the Program.cs.

---

Depending on the hosting model of your Blazor project you only need to apply either step 4.a or 4.b. You should not include both of them as that is generally not supported.

To Learn more about the different project types you can go to the official documentation.

---

4.a Blazor WebAssembly

This step is mandatory for Blazor WebAssembly(client-side) and also for ASP.NET Core hosted project types. You should place the code into the Program.cs of your client project.

// other usings
using Blazorise;
using Blazorise.Bootstrap;
using Blazorise.Icons.FontAwesome;

public class Program
{
  public static async Task Main( string[] args )
  {
    var builder = WebAssemblyHostBuilder.CreateDefault( args );

    builder.Services
      .AddBlazorise( options =>
      {
          options.ChangeTextOnKeyPress = true;
      } )
      .AddBootstrapProviders()
      .AddFontAwesomeIcons();

    builder.Services.AddSingleton( new HttpClient
    {
      BaseAddress = new Uri( builder.HostEnvironment.BaseAddress )
    } );

    builder.RootComponents.Add<App>( "#app" );

    var host = builder.Build();

    await host.RunAsync();
  }
}

4.b Blazor Server

This step is going only into the Startup.cs of your Blazor Server project.

// other usings
using Blazorise;
using Blazorise.Bootstrap;
using Blazorise.Icons.FontAwesome;

public class Startup
{
  public void ConfigureServices( IServiceCollection services )
  {
    services
      .AddBlazorise( options =>
      {
        options.ChangeTextOnKeyPress = true; // optional
      } )
      .AddBootstrapProviders()
      .AddFontAwesomeIcons();

    // other services
  }

  public void Configure( IComponentsApplicationBuilder app )
  {
    // other settings
    
    app.UseRouting();
    
    app.UseEndpoints( endpoints =>
    {
        endpoints.MapBlazorHub();
        endpoints.MapFallbackToPage( "/_Host" );
    } );
  }
}
