There are a few ways to consume a .NET Core API from a client-side application in ASP.NET MVC. Here are two of the most common methods:

  1. Using the HttpClient class: The HttpClient class is a class that provides a way to make HTTP requests from .NET Core applications. You can use the HttpClient class to make requests to a .NET Core API from your ASP.NET MVC application.
  2. Using the jQuery library: The jQuery library is a JavaScript library that provides a number of methods for making HTTP requests. You can use the jQuery library to make requests to a .NET Core API from your ASP.NET MVC application.

Here is an example of how to use the HttpClient class to consume a .NET Core API from a client-side application in ASP.NET MVC:

C#

using System.Net.Http;

public class HomeController
{
    public async Task<IActionResult> Index()
    {
        // Create an instance of the HttpClient class.
        HttpClient client = new HttpClient();

        // Make a GET request to the .NET Core API.
        HttpResponseMessage response = await client.GetAsync("https://api.example.com/products");

        // Check the status code of the response.
        if (response.StatusCode == HttpStatusCode.OK)
        {
            // Get the response body.
            string responseBody = await response.Content.ReadAsStringAsync();

            // Do something with the response body.
        }

        return View();
    }
}

Here is an example of how to use the jQuery library to consume a .NET Core API from a client-side application in ASP.NET MVC:

JavaScript

$(document).ready(function() {
    // Make a GET request to the .NET Core API.
    $.get("https://api.example.com/products", function(data) {
        // Do something with the response data.
    });
});

The best way to consume a .NET Core API from a client-side application in ASP.NET MVC will depend on the specific needs of your application. You should consider the factors such as the complexity of the API, the performance requirements of your application, and the familiarity of your developers with the different techniques.
