Question

我有以下课程GetProjectClass，public static async void GetProjects()

我想调用这个方法/类，所以它对异步编程来说是“新的东西” - 目标是以实用的方式连接到TFS

我有以下代码

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApplication2
{
public class GetProjectClass
{
public static async void GetProjects()
{
try
{
var personalaccesstoken = "PAT_FROM_WEBSITE";

using (HttpClient client = new HttpClient())
{
client.DefaultRequestHeaders.Accept.Add(

new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"));

client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic",
Convert.ToBase64String(System.Text.ASCIIEncoding.ASCII.GetBytes(string.Format("{0}:{1}", "", personalaccesstoken))));

using (HttpResponseMessage response = client.GetAsync(                    "https://{account}.visualstudio.com/DefaultCollection/_apis/projects").Result)

{response.EnsureSuccessStatusCode();
string responseBody = await response.Content.ReadAsStringAsync();
Console.WriteLine(responseBody);
}
}
}
catch (Exception ex)
{
Console.WriteLine(ex.ToString());
}
}
}
}

以下是我的program.cs文件，想要调用上面的内容，想知道这是否可能

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApplication2
{
    class Program
    {
        static void Main(string[] args)
        {

            GetProjectClass t = new GetProjectClass();
            t.GetProjects().Wait();
            Console.WriteLine("finished");
            Console.ReadKey();
        }
    }
}

从C# 7.1 you can use async main methods开始：

class Program
{
    static async Task Main(string[] args)
    {

        GetProjectClass t = new GetProjectClass();
        await t.GetProjects();
        Console.WriteLine("finished");
        Console.ReadKey();
    }
}

预C＃7.1这是不可能的。
注意：哟需要更改GetProjects才能返回任务以使其正常运行。

如何在主控制台应用程序中调用公共静态异步void？
