Getting Started with Blazor Server Side App in .NET CLI
19 Apr 20238 minutes to read
This article provides a step-by-step instructions for building Blazor Server App with Blazor Calendar
using the .NET CLI.
Prerequisites
Latest version of the .NET Core SDK. If you previously installed the SDK, you can determine the installed version by executing the following command in a command prompt (Windows) or terminal (macOS) or command shell (Linux).
dotnet --version
Create a Blazor Server side project using .NET CLI
Run the dotnet new blazorserver
command to create a new Blazor Server application in a command prompt (Windows) or terminal (macOS) or command shell (Linux).
dotnet new blazorserver -o BlazorApp
cd BlazorApp
This command creates new Blazor app project and places it in a new directory called BlazorApp
inside your current location. See Create Blazor app topic and dotnet new CLI command topics for more details and Benefits of using individual NuGet packages.
NOTE
If you have installed multiple SDK versions and need any specific framework version (net5.0/netcoreapp3.1) project, then add
-f
flag along withdotnet new blazorserver
comment. Refer here for the available options.
Install Syncfusion Blazor packages in the App
Syncfusion Blazor components are available in nuget.org. To use Syncfusion Blazor components in the application, add reference to the corresponding NuGet. Refer to NuGet packages topic for available NuGet packages list with component details.
Add Syncfusion.Blazor.Calendars
NuGet package to the application using the following command in the command prompt (Windows) or terminal (Linux and macOS) to install a NuGet package. See Install and manage packages using the dotnet CLI topics for more details.
dotnet add package Syncfusion.Blazor.Calendars --version 21.1.35
dotnet restore
Register Syncfusion Blazor Service
Open ~/_Imports.razor file and import the Syncfusion.Blazor
namespace.
@using Syncfusion.Blazor
Now, register the Syncfusion Blazor Service in the Blazor Server App. Here, Syncfusion Blazor Service is registered by setting IgnoreScriptIsolation property as true
to load the scripts externally in the next steps.
NOTE
From 2022 Vol-1 (20.1) version, the default value of
IgnoreScriptIsolation
is changed totrue
. It is not necessary to set theIgnoreScriptIsolation
property to refer scripts externally, since the default value has already been changed to true, and this property is obsolete.
-
For .NET 6 and .NET 7 app, open the ~/Program.cs file and register the Syncfusion Blazor Service.
-
For .NET 5 and .NET 3.X app, open the ~/Startup.cs file and register the Syncfusion Blazor Service.
using Microsoft.AspNetCore.Components;
using Microsoft.AspNetCore.Components.Web;
using Syncfusion.Blazor;
var builder = WebApplication.CreateBuilder(args);
// Add services to the container.
builder.Services.AddRazorPages();
builder.Services.AddServerSideBlazor();
builder.Services.AddSyncfusionBlazor();
var app = builder.Build();
....
using Syncfusion.Blazor;
namespace BlazorApp
{
public class Startup
{
...
public void ConfigureServices(IServiceCollection services)
{
services.AddRazorPages();
services.AddServerSideBlazor();
services.AddSyncfusionBlazor();
}
...
}
}
Add style sheet
Checkout the Blazor Themes topic to learn different ways (Static Web Assets, CDN and CRG) to refer themes in Blazor application, and to have the expected appearance for Syncfusion Blazor components. Here, the theme is referred using Static Web Assets. Refer to Enable static web assets usage topic to use static assets in your project.
To add theme to the app, Add Syncfusion.Blazor.Themes
NuGet package to the application using the following command in the command prompt (Windows) or terminal (Linux and macOS) to install a NuGet package.
NOTE
If you are using Syncfusion.Blazor single NuGet, you don’t have to refer Syncfusion.Blazor.Themes NuGet. Since style sheets already inside the assets of
Syncfusion.Blazor
NuGet.
dotnet add package Syncfusion.Blazor.Themes --version 21.1.35
dotnet restore
Then, the theme style sheet from NuGet can be referred inside the <head>
as follows,
- ~/Pages/_Layout.cshtml file for .NET 6.
- ~/Pages/_Host.cshtml file for .NET 3.X, .NET 5 and .NET 7
<head>
....
<link href="_content/Syncfusion.Blazor.Themes/bootstrap5.css" rel="stylesheet" />
<!--Refer theme style sheet as below if you are using Syncfusion.Blazor Single NuGet-->
<!--<link href="_content/Syncfusion.Blazor/styles/bootstrap5.css" rel="stylesheet" />-->
</head>
<head>
....
<link href="_content/Syncfusion.Blazor.Themes/bootstrap5.css" rel="stylesheet" />
<!--Refer theme style sheet as below if you are using Syncfusion.Blazor Single NuGet-->
<!--<link href="_content/Syncfusion.Blazor/styles/bootstrap5.css" rel="stylesheet" />-->
</head>
Add script reference
Checkout Adding Script Reference topic to learn different ways to add script reference in Blazor Application. In this getting started walk-through, the required scripts are referred using Static Web Assets externally inside the <head>
as follows. Refer to Enable static web assets usage topic to use static assets in your project.
- ~/Pages/_Host.cshtml file for .NET 3.X, .NET 5 and .NET 7.
- ~/Pages/_Layout.cshtml for .NET 6.
<head>
....
<link href="_content/Syncfusion.Blazor.Themes/bootstrap5.css" rel="stylesheet" />
<script src="_content/Syncfusion.Blazor.Core/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>
<!--Use below script reference if you are using Syncfusion.Blazor Single NuGet-->
<!--<script src="_content/Syncfusion.Blazor/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>-->
</head>
<head>
....
<link href="_content/Syncfusion.Blazor.Themes/bootstrap5.css" rel="stylesheet" />
<script src="_content/Syncfusion.Blazor.Core/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>
<!--Use below script reference if you are using Syncfusion.Blazor Single NuGet-->
<!--<script src="_content/Syncfusion.Blazor/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>-->
</head>
NOTE
Syncfusion recommends to reference scripts using Static Web Assets, CDN and CRG by disabling JavaScript isolation for better loading performance of the Blazor application. Generate scripts and theme assets using CRG by selecting the components you were using in the application.
Add Syncfusion Blazor component
- Open ~/_Imports.razor file or any other page under the
~/Pages
folder where the component is to be added and import theSyncfusion.Blazor.Calendars
namespace.
@using Syncfusion.Blazor
@using Syncfusion.Blazor.Calendars
- Now, add the Syncfusion Calendar component in .razor file. Here, the Calendar component is added in the ~/Pages/Index.razor page under the
~/Pages
folder.
<SfCalendar TValue="DateTime" />
- In the command prompt (Windows) or terminal (Linux and macOS) to run the following command to build and start the app. The app listening on
http://localhost:<port number>
and view it in the browser.
dotnet run
NOTE
You need to include a valid license key (either paid or trial key) within your applications. Refer to this help topic for more information.
