    WebClient is available from .net core 2.0

    var wc = new System.Net.WebClient();
    wc.DownloadFile( URL, @"c:\temp\myfile.txt");

    WebClient is not available in .NET Core. (UPDATE: It is from 2.0) The usage of HttpClient in the System.Net.Http is therefore mandatory:

    using System.Net.Http;
    using System.Threading.Tasks;
    ...
    public static async Task<byte[]> DownloadFile(string url)
    {
        using (var client = new HttpClient())
        {
    
            using (var result = await client.GetAsync(url))
            {
                if (result.IsSuccessStatusCode)
                {
                    return await result.Content.ReadAsByteArrayAsync();
                }
    
            }
        }
        return null;
    }
