Getting Started with Blazor AI AssistView in Blazor Web App

10 Jul 20267 minutes to read

This section briefly explains how to include the Blazor AI AssistView component in a Blazor Web App using Visual Studio, Visual Studio Code, and the .NET CLI.

Create a new Blazor Web App

Create a Blazor Web App using Visual Studio via Microsoft Templates or the Blazor Extension.

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

dotnet new blazor -o BlazorWebApp --interactivity Auto
cd BlazorWebApp
cd BlazorWebApp.Client

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

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

dotnet new blazor -o BlazorWebApp --interactivity Auto
cd BlazorWebApp
cd BlazorWebApp.Client

NOTE

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

Install the required Blazor packages

Install the Syncfusion.Blazor.InteractiveChat and Syncfusion.Blazor.Themes NuGet packages. All Syncfusion Blazor packages are available on nuget.org. See the NuGet packages topic for details. If using the WebAssembly or Auto render modes in the Blazor Web App, install these packages in the .Client project.

  1. Go to Tools → NuGet Package Manager → Manage NuGet Packages for Solution.
  2. Search the required NuGet packages (Syncfusion.Blazor.InteractiveChat 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.InteractiveChat -Version 34.1.29
Install-Package Syncfusion.Blazor.Themes -Version 34.1.29

Open the terminal and run the following commands.

dotnet add package Syncfusion.Blazor.InteractiveChat -v 34.1.29
dotnet add package Syncfusion.Blazor.Themes -v 34.1.29

Open the command prompt and run the following commands.

dotnet add package Syncfusion.Blazor.InteractiveChat -v 34.1.29
dotnet add package Syncfusion.Blazor.Themes -v 34.1.29

Add import namespaces

After the packages are installed, open the ~/_Imports.razor file in the .Client project and import the Syncfusion.Blazor and Syncfusion.Blazor.InteractiveChat namespaces.

@using Syncfusion.Blazor
@using Syncfusion.Blazor.InteractiveChat

Register the Blazor service

Open the Program.cs file in Blazor Web App and register the Blazor service. If the Interactive Render Mode is set to WebAssembly or Auto, register the Blazor service in Program.cs files of both the server and client projects in your Blazor Web App.

....
using Syncfusion.Blazor;
....
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 and script references in the ~/Components/App.razor file.

...
<link href="_content/Syncfusion.Blazor.Themes/fluent2.css" rel="stylesheet" />
...
<script src="_content/Syncfusion.Blazor.Core/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>

Add Blazor AI AssistView component

Open a Razor file located in the ~/Pages/*.razor (for example, Home.razor) and add the Blazor AI AssistView component inside the .Client project razor file.

NOTE

If the interactivity location is set to Per page/component in the Web App, define a render mode at the top of the razor file. (For example, InteractiveServer, InteractiveWebAssembly, or InteractiveAuto). If the Interactivity is set to Global with Auto or WebAssembly, the render mode is automatically configured in the App.razor file by default.

@rendermode InteractiveAuto

@using Syncfusion.Blazor.InteractiveChat

<div class="aiassist-container" style="height: 350px; width: 650px;">
    <SfAIAssistView PromptSuggestions="@promptSuggestions" PromptRequested="@PromptRequest"></SfAIAssistView>
</div>

@code
{
List<string> promptSuggestions = new List<string>
{
"How do I prioritize my tasks?",
"How can I improve my time management skills?"
};

public class AssistModel
{
    public string Prompt { get; set; }
    public string Response { get; set; }
}

private List<AssistModel> prompts = new List<AssistModel>()
{
    new AssistModel()
    {
        Prompt = "How do I prioritize my tasks?",
        Response = "Prioritize tasks by urgency and impact: tackle high-impact tasks first, delegate when possible, and break large tasks into smaller steps. For more assistance, feel free to ask—I'm here to help!"
    },
    new AssistModel()
    {
        Prompt = "How can I improve my time management skills?",
        Response = "To improve time management skills, try setting clear goals, using a planner or digital tools, prioritizing tasks, breaking tasks into smaller steps, and minimizing distractions. Regularly review and adjust your approach for better efficiency."
    }
};

private async Task PromptRequest(AssistViewPromptRequestedEventArgs args)
{
    await Task.Delay(3000);

    var isPromptFound = prompts.Any(prompt => prompt.Prompt == args.Prompt);
    var promptData = prompts.FirstOrDefault(prompt => prompt.Prompt == args.Prompt);

    var defaultResponse = "For real-time prompt processing, connect the AI AssistView component to your preferred AI service, such as OpenAI or Azure Cognitive Services. Ensure you obtain the necessary API credentials to authenticate and enable seamless integration.";

    args.Response = isPromptFound ? promptData.Response : defaultResponse;
}
}

Run the application

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

Open the terminal and navigate to the main project folder (for example, BlazorWebApp) and run the following command.

cd ..
cd BlazorWebApp
dotnet run

Open the command prompt and navigate to the main project folder (for example, BlazorWebApp) and run the following command.

cd ..
cd BlazorWebApp
dotnet run
Blazor AI AssistView default prompt

Note: Starting from version 33.1x, when a user submits a prompt to the AI AssistView, the component automatically scrolls and focuses on the latest prompt and response. This behavior eliminates the need for users to manually scroll down to see the new response, ensuring they always view the most recent AI response without interruption. Prior to version 33.1x, the previous responses remained visible when new responses were added.
