GitHub API access with Personal Access Token using C# HttpClient and .NET Core

Program.cs

public class Program
{
    public static void Main(string[] args)
    {
        Task.WaitAll(ExecuteAsync());
        Console.ReadLine();
    }

    public static async Task ExecuteAsync()
    {
        HttpClient client = new HttpClient();
        client.BaseAddress = new Uri("https://api.github.com");
        var token = "<token>";

        client.DefaultRequestHeaders.UserAgent.Add(new System.Net.Http.Headers.ProductInfoHeaderValue("AppName", "1.0"));
        client.DefaultRequestHeaders.Accept.Add(new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"));
        client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Token", token);

        var response = await client.GetAsync("/user");
    }
}

Really appreciated, thanks!
