Getting started with Syncfusion Blazor - WebAssembly App in .NET Core CLI

This article provides a step-by-step introduction to configure Syncfusion Blazor for Blazor setup, build and run a simple Blazor WebAssembly application using .NET Core CLI.

Note: Starting with version (2019 Volume 4), you need to include a valid license key (either paid or trial key) within your applications. Please refer to this help topic for more information.

Blazor is an unsupported, experimental web framework that shouldn’t be used for production workloads at this time.


Create a Blazor WebAssembly project using .NET Core CLI

  1. Install the Blazor project templates by using below command line in the command prompt:

    dotnet new -i Microsoft.AspNetCore.Blazor.Templates::3.1.0-preview4.19579.2
  2. Once project templates installed, run the following command line to create a new Blazor WebAssembly application.

        dotnet new blazorwasm -o WebApplication1
        cd WebApplication1

Importing Syncfusion Blazor component in the application

  1. Now, add Syncfusion.EJ2.Blazor NuGet package to the new application using below command line.

        dotnet add package Syncfusion.EJ2.Blazor -v
        dotnet restore
  2. The Syncfusion Blazor package will be included in the newly created project after the installation process is completed.

  3. Open ~/_Imports.razor file and import the Syncfusion.EJ2.Blazor.

    @using Syncfusion.EJ2.Blazor
    @using Syncfusion.EJ2.Blazor.Calendars
  4. Open the ~/Startup.cs file and register the Syncfusion Blazor Service.

    using Syncfusion.EJ2.Blazor;
    namespace WebApplication1
        public class Startup
            public void ConfigureServices(IServiceCollection services)
  5. Add the client-side resource through CDN in the <head> element of the ~/wwwroot/index.html page.

        <link href="" rel="stylesheet" />
        <script src=""></script>
        <script src=""></script>

    Note: For production purpose and minimal requirement, Syncfusion provides an option to generate scripts and styles of selective control by using the Custom Resource Generator (CRG) web tool. Refer to this help documentation link for more details on CRG.

  6. Now, add the Syncfusion Blazor components in any web page (razor) in the ~/Pages folder. For example, the calendar component is added in the ~/Pages/Index.razor page.

    <EjsCalendar TValue="DateTime"></EjsCalendar>
  7. Run dotnet run command to run the application. The Syncfusion Blazor Calendar component will render in the web browser.
