调试时调用async方法导致控制台应用意外退出问题求助

• 该问题仅在控制台应用、Windows服务应用中出现，尚未在Windows Forms或WPF应用中测试
• 调试代码时，只要执行到带await的async调用，调试会话就会意外终止，无法继续调试
• 当前临时解决办法是改用Task.Run()，但调试时修改所有async调用语法、部署时再改回原写法，操作十分繁琐

存在调试问题的代码（部署后可正常运行） #

var response = await httpClient.SendAsync(request);

调试临时替代代码 #

//var response = await httpClient.SendAsync(request);
var task = Task.Run(() => httpClient.SendAsync(request));
task.Wait();
var response = task.Result;

完整示例代码 #

private static async Task<string> SendRequest()
{
    string result = "";
    string url = "http://localhost:5119/WeatherForecast";
    var URL = new Uri(url);
    var method = new HttpMethod("GET");
    using (var request = new HttpRequestMessage(method, URL))
    {
        var response = await httpClient.SendAsync(request);

        //var task = Task.Run(() => httpClient.SendAsync(request));
        //task.Wait();
        //var response = task.Result;
        result = await response.Content.ReadAsStringAsync();
    }

    return result;
}
