Whats the purpose of asp net core hosted in blazor wasm app

Introduction

ASP.NET is a popular programming language used for building web applications. It provides a framework for developing , web services, and web applications. One of the key features of ASP.NET is its ability to host applications in various environments, including Blazor WebAssembly (WASM) apps.

Understanding ASP.NET Core Hosting in Blazor WebAssembly Apps

Blazor WebAssembly is a client-side web framework that allows developers to interactive web applications using C# instead of JavaScript. It runs in the browser and can be hosted in different environments, including ASP.NET Core.

ASP.NET Core hosting in Blazor WebAssembly apps provides a server-side component model for building web applications. It allows developers to write server-side code that can be executed on the server and interact with the client-side code running in the browser.

Purpose of ASP.NET Core Hosting in Blazor WebAssembly Apps

The purpose of ASP.NET Core hosting in Blazor WebAssembly apps is to provide a seamless integration between the server-side and client-side components of a web . It allows developers to leverage the of C# and the .NET ecosystem to build rich and interactive web applications.

By hosting Blazor WebAssembly apps in ASP.NET Core, developers can take advantage of the server-side capabilities provided by ASP.NET Core, such as authentication, authorization, and data access. They can also benefit from the performance optimizations and scalability features offered by ASP.NET Core.

Example: ASP.NET Core Hosting in Blazor WebAssembly App


using Microsoft..Components.WebAssembly.Hosting;
using Microsoft.Extensions.DependencyInjection;
using System;
using System.Net.Http;
using System.Threading.Tasks;

namespace BlazorApp
{
    public  
    {
        public static async Task Main(string[] args)
        {
            var builder = WebAssemblyHostBuilder.CreateDefault(args);
            builder.RootComponents.Add("app");

            builder.Services.AddScoped(sp => new  { BaseAddress = new Uri(builder.HostEnvironment.BaseAddress) });

            await builder.Build().RunAsync();
        }
    }
}

In the above example, we can see how an ASP.NET Core hosting is set up for a Blazor WebAssembly app. The Main method creates a WebAssemblyHostBuilder instance and configures it to use the App component as the root component of the application.

The Services property of the WebAssemblyHostBuilder is used to register dependencies. In this case, a HttpClient instance is registered with the base address of the host environment.

Finally, the Build method is called to build the host, and the RunAsync method is invoked to start the application.

Conclusion

ASP.NET Core hosting in Blazor WebAssembly apps provides a powerful framework for building web applications using C#. It allows developers to leverage the benefits of both server-side and client-side programming paradigms, resulting in rich and interactive web applications.

By hosting Blazor WebAssembly apps in ASP.NET Core, developers can take advantage of the extensive features and capabilities offered by ASP.NET Core, making it a versatile and efficient platform for web development.
