Microsoft Templates (CLI)

  • 4 minutes to read

Important

Ensure your system meets these requirements.

This topic describes how to:

1. Create a New Project

Run one of the following commands to create a project:

  • Blazor Server App 

    dotnet new blazorserver -o MyBlazorServerProject
cd MyBlazorServerProject

  • Blazor WebAssembly App

    dotnet new blazorwasm -o MyBlazorWasmProject
cd MyBlazorWasmProject

  • Blazor Hosted WebAssembly App

    dotnet new blazorwasm -ho -o MyBlazorWasmHostedProject
cd MyBlazorWasmHostedProject

2. Obtain Your DevExpress NuGet Feed

You need to obtain your personal NuGet feed URL to access the DevExpress.Blazor NuGet package from your project.

  1. Make sure your DevExpress.com account has access to Blazor UI Components. This product line is available as part of the Universal, DXperience, or ASP.NET subscription. Refer to the subscription comparison matrix for more information.

  2. Use your DevExpress credentials to log into nuget.devexpress.com.

  3. Obtain your NuGet feed URL and copy it to the clipboard.

    NuGet Feed

    You can find the same URL in the Download Manager.

3. Register the NuGet Feed as a Package Source

Add the feed as a package source to your NuGet configuration files.

dotnet nuget add source https://nuget.devexpress.com/{your-feed-url}/api -n DevExpress

An error can occur if the specified source is already in the source list. Run dotnet nuget list source to view all the configured sources. Make sure that the specified source and the nuget.org package source are enabled. To enable them, use the dotnet nuget enable source command.

4. Install the DevExpress Blazor NuGet Package

Run the following commands to add the DevExpress.Blazor NuGet package to the newly created application:

dotnet add package DevExpress.Blazor
dotnet restore

5. Register DevExpress Resources

Blazor Server

  1. Add the following line to the Pages/_Host.cshtml file’s HEAD section: 

    <head>
    <!--...-->
    <link href="_content/DevExpress.Blazor/dx-blazor.css" rel="stylesheet" />
</head>

  2. Register the DevExpress.Blazor namespace in the _Imports.razor file:

    @using DevExpress.Blazor

  3. DevExpress Blazor components use an RCL (Razor class library) with static assets to share resources. Call the UseStaticWebAssets method on the host builder in the Program.cs file to enable the application to load client-side resources. 

    public class Program {
    // ...

    public static IHostBuilder CreateHostBuilder(string[] args) =>
        Host.CreateDefaultBuilder(args)
            .ConfigureWebHostDefaults(webBuilder => {
                webBuilder.UseStartup<Startup>();
                webBuilder.UseStaticWebAssets();
            });
}

    Refer to the following topics for more information: Consume content from a referenced RCL and Troubleshooting: Failed to load resource.

  4. (Optional) Apply a DevExpress Bootstrap theme. We use the DevExpress Blazing Berry theme in our demos and documentation.

Blazor WebAssembly

  1. Add the following line to the wwwroot/index.html file’s HEAD section: 

    <head>
    <!--...-->
    <link href="_content/DevExpress.Blazor/dx-blazor.css" rel="stylesheet" />
</head>

  2. Call the AddDevExpressBlazor(IServiceCollection, Action<GlobalOptions>) method from your project’s Program.Main() method:

    using Microsoft.Extensions.DependencyInjection;

public class Program {
    public static async Task Main(string[] args) {
        var builder = WebAssemblyHostBuilder.CreateDefault(args);
        // ...
        builder.Services.AddDevExpressBlazor();
        await builder.Build().RunAsync();
    }
}

  3. Register the DevExpress.Blazor namespace in the _Imports.razor file:

    @using DevExpress.Blazor

  4. Configure the linker as described in the following topic: Configure the Linker for ASP.NET Core Blazor.

    Note

    If you enabled the ASP.NET Core hosted option when you create the project, make sure that the server-side project is set as the solution’s startup project.

  5. (Optional) Apply a DevExpress Bootstrap theme. We use the DevExpress Blazing Berry theme in our demos and documentation.

6. Add DevExpress Blazor Components

Add DevExpress Blazor components to any .razor file in the Pages folder. For example, the following code demonstrates how to add a DxCalendar component to Pages/Index.razor:

@page "/"

<DxCalendar @bind-SelectedDate="@SelectedDate" />

@code{
    DateTime SelectedDate { get; set; } = DateTime.Now;
}

The following help topics contain information on how to add different DevExpress Blazor components:

7. Run the Application

Run a Server or WebAssembly application:

dotnet run

Run a hosted WebAssembly application:

cd Server
dotnet run

The project starts listening on https://localhost:5000. Open it in the browser.

Run the application
