Using .NET CLI Templates

Quickly set up a Blazor application using the preconfigured Syncfusion Web App Template.

First, install the template using the .NET CLI.

dotnet new install Syncfusion.Blazor.WebApp.Templates

Next, create a new project with following command.

dotnet new syncfusionblazorwebapp --name MyApp --interactivity Server

After creating the project, navigate to the main project folder (for example, MyApp) and run the following command.

  • .NET CLI
    • cd MyApp
dotnet run

    Manually creating a new Blazor Server App

    Create a Blazor Server App by using the Blazor Web App template in Visual Studio via Microsoft Templates or the Syncfusion® Blazor Extension.

    Run the following command to create a new Blazor Server App.

    dotnet new blazor -o BlazorApp --interactivity Server
cd BlazorApp

    Alternatively, create a Blazor Server App using Visual Studio Code via Microsoft Templates or the Syncfusion® Blazor Extension, or the C# Dev Kit extension.

    Configure the appropriate Interactive render mode and Interactivity location while creating a Blazor Server App. For detailed information, refer to the interactive render mode documentation.

    Install the required Blazor packages

    Install the Syncfusion.Blazor.FileManager and Syncfusion.Blazor.Themes NuGet packages. All Syncfusion Blazor packages are available on nuget.org. See the NuGet packages topic for details.

    1. Go to Tools → NuGet Package Manager → Manage NuGet Packages for Solution.
    2. Search the required NuGet packages (Syncfusion.Blazor.FileManager and Syncfusion.Blazor.Themes) and install them.

    Alternatively, you can install the same packages using the Package Manager Console with the following commands.

    Install-Package Syncfusion.Blazor.FileManager -Version 35.1.37
Install-Package Syncfusion.Blazor.Themes -Version 35.1.37

    Open the terminal and run the following commands.

    dotnet add package Syncfusion.Blazor.FileManager -v 35.1.37
dotnet add package Syncfusion.Blazor.Themes -v 35.1.37

    Add import namespaces

    After the packages are installed, open the ~/_Imports.razor file and import the Syncfusion.Blazor and Syncfusion.Blazor.FileManager namespaces.

    @using Syncfusion.Blazor
@using Syncfusion.Blazor.FileManager

    Register the Blazor service

    Open the Program.cs file in Blazor Server App and register the Blazor service and include the required namespace reference using Syncfusion.Blazor; at the top.

    builder.Services.AddSyncfusionBlazor();

    Add stylesheet and script resources

    The theme stylesheet and script can be accessed from NuGet through Static Web Assets. Include the stylesheet at the end of the <head> section in the App.razor file.

    <link href="_content/Syncfusion.Blazor.Themes/fluent2.css" rel="stylesheet" />

    Include the required script references at the end of the <body> section in the App.razor file to enable Blazor File Manager functionality.

    <script src="_content/Syncfusion.Blazor.Core/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>

    Add Blazor File Manager component

    Open a Razor file located in the ~/Components/Pages/*.razor (for example, Home.razor) and add the Blazor File Manager component inside the Razor file.

    If the interactivity location is set to Per page/component, define a render mode at the top of the Razor file (for example, InteractiveServer). If the Interactivity is set to Global, the render mode is automatically configured in the App.razor file by default.

    @rendermode InteractiveServer

<SfFileManager TValue="FileManagerDirectoryContent">
    <FileManagerAjaxSettings Url="https://physical-service.syncfusion.com/api/FileManager/FileOperations"
                             UploadUrl="https://physical-service.syncfusion.com/api/FileManager/Upload"
                             DownloadUrl="https://physical-service.syncfusion.com/api/FileManager/Download"
                             GetImageUrl="https://physical-service.syncfusion.com/api/FileManager/GetImage">
    </FileManagerAjaxSettings>
</SfFileManager>

    Run the application

    Press Ctrl+F5 (Windows) or ⌘+F5 (macOS) to launch the application. The Blazor File Manager component will render in your default web browser.

    Open the terminal and run the following command.

    dotnet run
