![]() You’ll observe that the breakpoints are hit when you run the application. Now set a breakpoint in the ConfigureServices and Configure methods of the Startup class we created earlier. To do this, replace the existing code of the Program class with the following code: var builder = WebApplication.CreateBuilder(args) var startup = new Startup(builder.Configuration) startup.ConfigureServices(builder.Services) var app = builder.Build() startup.Configure(app) app.Run() Your Program class code should refer to the newly created Startup class. The UseRouting and UseEndpoints methods are used to add and configure the routing middleware to the request processing pipeline. Here is how a minimal Program class would look in. Although you can put Main() anywhere in your project, it is typically located in a class named Program, stored in a file called Program.cs. ![]() Because Main() is the entry point of your application, you can have one and only one Main() method in your project. ![]() ![]() The Main() method is the entry point in a. NET Core project needs an entry point to start. The ConfigureWebHostDefaults() extension method can be used to configure a web application host by selecting Kestrel as the web server and configuring it using the application’s hosting configuration providers. Note that both WebApplication and WebApplicationBuilder classes were introduced in ASP.NET Core 6. UseContentRoot(Directory.GetCurrentDirectory()). The following code snippet shows how the CreateDefaultBuilder method can be used: var host = new WebHostBuilder(). This method is used to initialize a new instance of the WebHostBuilder class with pre-configured defaults. You can also call the CreateDefaultBuilder method to create a host. IEndpointRouteBuilder – used to add endpoints.IApplicationBuilder – used to build the middleware pipeline.IHost – used to start and stop the host.The WebApplication class implements the following interfaces: The following code snippet illustrates this: var builder = WebApplication.CreateBuilder(args) var app = builder.Build() app.Run() A host builder is an instance of IHostBuilder. To create a host in ASP.NET Core 6, you should call the Build().Run() method on a host builder. A host is created, configured, and executed using the code written in the Program class. The host encapsulates resources such as logging, configuration, dependency injection (DI), and any IHostedService implementations. NET Core web application runs inside a host that handles application startup, web server configuration, etc. We’ll use this project in the subsequent sections of this article. This will create a new ASP.NET Core 6 Web API project in Visual Studio 2022. Ensure that the check boxes “Enable Docker,” “Configure for HTTPS,” and “Enable Open API Support” are unchecked as we won’t be using any of those features here.Leave the “Authentication Type” as “None” (default). NET 6.0 as the target framework from the drop-down list at the top. In the “Additional Information” window shown next, select.Optionally check the “Place solution and project in the same directory” check box, depending on your preferences.In the “Configure your new project” window, specify the name and location for the new project.In the “Create new project” window, select “ASP.NET Core Web API” from the list of templates displayed.Following these steps will create a new ASP.NET Core Web API 6 project in Visual Studio 2022: Create an ASP.NET Core Web API project in Visual Studio 2022įirst off, let’s create an ASP.NET Core project in Visual Studio 2022.
