11 Oct 20245 minutes to read

This section briefly explains about how to include Blazor AI AssistView component in your Blazor Web App using Visual Studio.

Prerequisites

Create a new Blazor Web App

You can create a Blazor Web App using Visual Studio 2022 via Microsoft Templates or the Syncfusion Blazor Extension.

You need to configure the corresponding Interactive render mode and Interactivity location while creating a Blazor Web Application.

Install Syncfusion Blazor InteractiveChat and Themes NuGet in the App

To add Blazor AI AssistView component in the app, open the NuGet package manager in Visual Studio (Tools → NuGet Package Manager → Manage NuGet Packages for Solution), search and install Syncfusion.Blazor.InteractiveChat and Syncfusion.Blazor.Themes.

If you utilize WebAssembly or Auto render modes in the Blazor Web App need to be install Syncfusion Blazor components NuGet packages within the client project.

Alternatively, you can utilize the following package manager command to achieve the same.

Install-Package Syncfusion.Blazor.InteractiveChat -Version 27.2.2
Install-Package Syncfusion.Blazor.Themes -Version 27.2.2

NOTE

Syncfusion Blazor components are available in nuget.org. Refer to NuGet packages topic for available NuGet packages list with component details.

Register Syncfusion Blazor Service

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

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

Now, register the Syncfusion Blazor Service in the ~/Program.cs file of your Blazor Web App.

If you select an Interactive render mode as WebAssembly or Auto, you need to register the Syncfusion Blazor service in both ~/Program.cs files of 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 reference in the <head> section and the script reference at the end of the <body> in the ~/Components/App.razor file as shown below:

<head>
    ....
    <link href="_content/Syncfusion.Blazor.Themes/bootstrap5.css" rel="stylesheet" />
</head>

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

NOTE

Check out the Blazor Themes topic to discover various methods (Static Web Assets, CDN, and CRG) for referencing themes in your Blazor application. Also, check out the Adding Script Reference topic to learn different approaches for adding script references in your Blazor application.

Add Syncfusion Blazor AI AssistView component

Add the Syncfusion Blazor AI AssistView component in the ~Pages/.razor file. If an interactivity location as Per page/component in the web app, define a render mode at the top of the ~Pages/.razor component, as follows:

@* desired render mode define here *@
@rendermode InteractiveAuto
<div class="aiassist-container" style="height: 350px; width: 650px;">
    <SfAIAssistView></SfAIAssistView>
</div>
  • Press Ctrl+F5 (Windows) or ⌘+F5 (macOS) to launch the application. This will render the Syncfusion Blazor AI AssistView component in your default web browser.

Configure suggestions and responses

You can use the PromptSuggestions property to add prompt suggestions and the PromptRequested event to add responses when the prompt matches the specified prompts data otherwise, the default response will be displayed.

@* desired render mode define here *@
@rendermode InteractiveAuto
<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;
    }
}
