Can you create in x++ RESTClient to make GET, POST, PUT, DELETE requests?
 In X++, it is not possible to create a REST client directly because the X++ language is primarily used for developing business logic in Microsoft Dynamics 365 Finance and Operations. However, you can use the .NET Framework's `HttpClient` class to make REST requests from X++. Here's an example of how you can create a class library in C# that uses `HttpClient` to make GET, POST, PUT, and DELETE requests, and then call that library from X++.

First, create a new class library project in Visual Studio and add the following code to the `Program.cs` file:
```csharp
using System;
using System.Net.Http;
using System.Threading.Tasks;

namespace RestClient
{
    public class RestClient
    {
        private readonly HttpClient _client;

        public RestClient(string baseAddress)
        {
            _client = new HttpClient { BaseAddress = new Uri(baseAddress) };
        }

        public async Task<HttpResponseMessage> GetAsync(string requestUri)
        {
            return await _client.GetAsync(requestUri);
        }

        public async Task<HttpResponseMessage> PostAsync(string requestUri, HttpContent content)
        {
            return await _client.PostAsync(requestUri
Here is an example of how you can create a `RESTClient` class in X++ to make GET, POST, PUT, and DELETE requests:
```
static class RESTClient
{
    private static System.Net.Http.HttpClient _httpClient;

    static RESTClient()
    {
        _httpClient = new System.Net.Http.HttpClient();
    }

    public static System.Net.Http.HttpResponseMessage Get(string url)
    {
        return _httpClient.GetAsync(url).Result;
    }

    public static System.Net.Http.HttpResponseMessage Post(string url, string content)
    {
        var httpContent = new System.Net.Http.StringContent(content, System.Text.Encoding.UTF8, "application/json");
        return _httpClient.PostAsync(url, httpContent).Result;
    }

    public static System.Net.Http.HttpResponseMessage Put(string url, string content)
    {
        var httpContent = new System.Net.Http.StringContent(content, System.Text.Encoding.UTF8, "application/json");
        return _httpClient.PutAsync(url, httpContent).Result;
    }

    public static System.Net.Http.HttpResponseMessage Delete(string url)
    {
        return _httpClient.DeleteAsync(url).Result;
    }
}
```
This class uses the `System.Net.Http` namespace to create an instance of `HttpClient`, which is used to make the REST requests.

You can then use this class to make requests like this:
```
static void MakeRESTRequests(Args _args)
{
    // GET request
    var response = RESTClient
