So, create a basic Blazor Server project by typing the following command in a terminal window: dotnet new blazorserver -o QuizManager This command uses the blazorserver template to generate the project for your application in the QuizManager folder. Place this code between services.AddAuthentication and services.AddControllersWithViews. HTTPClient in ConfigureServices () method in Startup.cs. The Enhanced quickstart will build upon this sample to apply better design patterns. You are mixing UI and server code. (Azure Function, Grpc, ASP.NET Web API). Some components only show a portion of their Razor markup in an article. Step 5.1: Add a folder with the name "Services" in the root of your Blazor web application project. The second registers the service that tracks the token, and the third creates a client with the base API address pre-configured. Append /api/data/v9.0/ to the end of the URL so it looks like this: Add this using statement to the file Startup.cs. How to deploy a website on Google Compute Engine / Google Cloud, Understanding the Key Types of Enterprise Mobile Solutions, What Is Web3Why Elastos Is Beyond The Competition. Blazor Server and Blazor WebAssembly (also known as Blazor Wasm) differ in many ways. The Server project implements the OpenID Connect user interaction flow and authenticates the client as well as the user authentication. Now you will update your app's registration and code to pull a user's email and display the messages within the app. After call completion, the UserId property value is displayed. Step 1 Step 2 In this step we will select " Blazor WebAssembly App " project type. For this, open up the Package Manager Console and type in the following. Tutorial: Enable your Blazor Server app to sign-in users and call APIs with the Microsoft identity platform. And it's time to rebuild a similar web application that uses ASP.NET Core 6.0 MVC, Razor Pages, Blazor Server, API controllers, and minimal APIs together in a single project. Step 5.3: Here we will write all the abstract functions that we may need in my application for reusable logic. Blazor SignalR sample app (ASP.NET Core 6.0): For more information, see Use ASP.NET Core SignalR with Blazor. The application requires some extra steps to capture the authentication token and pass it to the Web API request. Follow the instructions in Register an application with these additions: Under Manage, select Authentication > Implicit grant and hybrid flows. We can use either Visual Studio 2022 or Visual Studio Code . You can expand on the example to perform more complex operations, and wrap the HttpClient object in a service class to handle the permissions. This will be our serverless application that handles requests to a pseudo database. So, let's first modify the Program.cs class: public class Program { public static async Task Main(string[] args) { var builder = WebAssemblyHostBuilder.CreateDefault(args); Microsoft Graph offers a range of APIs that provide access to your users' Microsoft 365 data. Download File from Server with Blazor App. The reason is: You need to scale both the Blazor Server host and the API host. You will be greeted by a whole host of files including Program.cs and Startup.cs which will be explained shortly. The registration will happen automatically as part of the template creation, but will require additional updates in the Azure portal. You will see a URL like this: https://{org}.crm.dynamics.com where {org} is the environment name. We can give a valid name and physical location to the project. In the Start folder, you can find two projects. A blazor component file consists of both c# and razor syntax. The Blazor application consists of three projects. Examples in this article In this article's component examples, a hypothetical todo list web API is used to create, read, update, and delete (CRUD) todo items on a server. After we create the HttpClient instance we need to send the request and then contain the response of the request in a variable with the return type of this variable being HttpResponseMessage and we do this with the below code. For example, a component that requires a list of. Right, time for some code, so our first call of action is to add a HttpClient service to the Startup.cs file as the Blazor server app does not include the service by default. The startup file is used to initialise services that are required to run the app, by default the startup file has a service WeatherForecastService. In the Azure portal, select your app in App registrations. After clicking the "Create" button, wait for Visual Studio to finish creating the project.

Most demos of Blazor Server just connect directly using EF. As suggested if you used blazor WASM, then it and the mobile app would be using the same server code and api. To do this navigate to the top line of the file. We can now hit F5 to run the application. After thead we now need to add tbody to contain the main content of the table. This tutorial will focus on explaining what Blazor is as well as the difference between Blazor server and Blazor web Assembly. A second API is implemented for separate clients and the API is protected using JWT tokens. Learn more. Finally, because the app calls a protected API (in this case Microsoft Graph), it needs a client secret in order to verify its identity when it requests an access token to call that API. You may have noticed at this point that there's no Server project. Blazor is Microsoft's newest web framework. However, the program file is present in both projects. We have now finished the majority of the C# code and have retrieved the API data, we can now look at using this data to show to the user in a pretty way. After sending a request to the API, the API will process the request then return the response to your HttpClient. The third-party API we will consume is Nager.Date which is a worldwide public holidays API. A HttpClient will allow us to send http requests and receive responses in order to manipulate them to show it to the user. JWT Auth in Blazor using Web API Calling Example.
