Installing Syncfusion Blazor packages in the application

You can use any one of the below standard to install the Syncfusion Blazor library in your application.

Using Syncfusion Blazor individual NuGet Packages [New standard]

Starting with Volume 4, 2020 (v18.4.0.30) release, Syncfusion provides individual NuGet packages for our Syncfusion Blazor components. We highly recommend this new standard for your Blazor production applications. Refer to this section to know the benefits of the individual NuGet packages.

  1. Now, install Syncfusion.Blazor.Calendars NuGet package to the new application using the NuGet Package Manager. For more details about available NuGet packages, refer to the Individual NuGet Packages documentation.

  2. Right-click the project,and then select Manage NuGet Packages.

    nuget explorer

  3. Search Syncfusion.Blazor.Calendars keyword in the Browse tab and install Syncfusion.Blazor.Calendars NuGet package in the application.

    select nuget

  4. The Syncfusion Blazor Calendars package will be included in the newly created project once the installation process is completed.

  5. Add the Syncfusion bootstrap4 theme in the <head> element of the ~/wwwroot/index.html page.

    <head>
    ....
    ....
    <link href="_content/Syncfusion.Blazor.Themes/bootstrap4.css" rel="stylesheet" />
</head>

    Warning: Syncfusion.Blazor package should not be installed along with individual NuGet packages. Hence, you have to add the above Syncfusion.Blazor.Themes static web assets (styles) in the application.

Using Syncfusion.Blazor NuGet Package [Old standard]

Warning: If you prefer the above new standard (individual NuGet packages), then skip this section. Using both old and new standards in the same application will throw ambiguous compilation errors.

  1. Now, install Syncfusion.Blazor NuGet package to the newly created application by using the NuGet Package Manager. Right-click the project and then select Manage NuGet Packages.

    nuget explorer

  2. Search Syncfusion.Blazor keyword in the Browse tab and install Syncfusion.Blazor NuGet package in the application.

    select nuget

  3. The Syncfusion Blazor package will be installed in the project once the installation process is completed.

  4. Add the Syncfusion bootstrap4 theme in the <head> element of the ~/wwwroot/index.html page.

    <head>
    ....
    ....
     <link href="_content/Syncfusion.Blazor/styles/bootstrap4.css" rel="stylesheet" />
</head>

    Note: The same theme file can be referred through the CDN version by using https://cdn.syncfusion.com/blazor/18.4.35/styles/bootstrap4.css.

Adding Syncfusion Blazor component and running the application

  1. Open ~/_Imports.razor file and import the Syncfusion.Blazor namespace.

    @using Syncfusion.Blazor
@using Syncfusion.Blazor.Calendars

  2. Open the ~/Program.cs file and register the Syncfusion Blazor Service.

    using Syncfusion.Blazor;

namespace WebApplication1
{
    public class Program
    {
        public static async Task Main(string[] args)
        {
            ....
            ....
            builder.Services.AddSyncfusionBlazor();
            await builder.Build().RunAsync();
        }
    }
}

  3. 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.

    <SfCalendar TValue="DateTime"></SfCalendar>

  4. Run the application. Then, the Syncfusion Blazor Calendar component will be rendered in the default web browser.
