异步抛出单声道堆栈溢出

我正在为Mono编写一个控制台应用程序，试图让HttpClient下载一些内容并将其与Json.NET反序列化。

我遇到的问题是，当我调用异步方法时，我得到一个堆栈溢出。

它是这样的，简化到正文的核心:

public static void Main(string[] args){
  ...
  Manager man = new Manager(){...}; // setting up target url, timeouts etc
  man.RenewAuth().Wait(); //it's async but the first time it runs synchronously
  ...
}
public class Manager{
...
async Task<T> GetAsync<T> (string urlAdd)
{
  var httpRes = await Client.GetAsync (Client.BaseAddress + urlAdd);
  string s = await httpRes.Content.ReadAsStringAsync ();
  var deserialized = JsonConvert.DeserializeObject<T> (s);
  return deserialized  ;
}
public async Task RenewAuth () // 
{
  ... // logging in, setting up etc
  // THIS WORKS:
  var aKey = GetAsync<AuthKey> ("/AuthKey?email=" + email).Result; 
  // THIS DOESN'T WORK, CAUSES STACK OVERFLOW:
  var aKey = await GetAsync<AuthKey> ("/AuthKey?email=" + email); 
  ... // store the api auth key from aKey and return
}
}

在控制台中，我得到这个:

事实证明，只有在附加了调试器时才会发生这种情况，否则代码可以正常工作。
