dotnet new webapi -n MyWebAPI First, you need to have .NET Core SDK installed on your machine. You can download it from the official .NET website if you haven't already: https://dotnet.microsoft.com/download Once you have .NET Core SDK installed, follow these steps to create a new Web API project: Open a terminal or command prompt. Run the following command to create a new ASP.NET Core Web API project: dotnet new webapi -n MyWebAPI This command will create a new directory named MyWebAPI containing the basic structure of a Web API project. Navigate into the project directory: cd MyWebAPI Open the project in your preferred code editor. For example, if you're using Visual Studio Code: code . Now, let's create a simple API for managing items. In Controllers directory, you'll find WeatherForecastController.cs . You can rename it to ItemsController.cs and modify it to create an Items API. Here's an example of ItemsController.cs : using System; using System.Collections.Generic; using System.Linq; using Microsoft.AspNetCore.Mvc; namespace MyWebAPI.Controllers { [ApiController] [Route("[controller]")] public class ItemsController : ControllerBase { private static List _items = new List (); [HttpGet] public IEnumerable Get() { return _items; } [HttpPost] public IActionResult Post([FromBody] string item) { _items.Add(item); return Ok(); } [HttpDelete("{item}")] public IActionResult Delete(string item) { if (_items.Contains(item)) { _items.Remove(item); return Ok(); } else { return NotFound(); } } } } In this controller: [ApiController] attribute denotes that this controller will respond to HTTP API requests. [Route("[controller]")] specifies that the controller will respond to requests with a route that starts with /items . Get() method returns the list of items. Post() method adds a new item to the list. Delete() method removes an item from the list. Now, you can run your API by executing the following command in your terminal or command prompt: dotnet run Your API will be hosted on http://localhost:5000 . You can test the API using tools like Postman or curl. Here are some example requests: GET /items : Retrieve the list of items. POST /items with JSON body: Add a new item to the list. DELETE /items/{item} : Remove a specific item from the list. That's a basic example of how you can create a Web API using ASP.NET Core MVC. You can expand upon this example by adding more complex logic, database integration, authentication, and authorization as needed.
