我有一个类似下面的课程

public class ImageUploader
{
   ....

   public Task<string> Upload()
   {
      return new Task<string>(
                () =>
                    {
                        ....

                        return UploadedFilePath;
                    }
            );
   }
   ....
}

然后我就像这样使用它

var uploadIcon = new ImageUploader();
var uploadLogo = new ImageUploader();

var uploadIconTask = uploadIcon.Upload();
var uploadLogoTask = uploadLogo.Upload();

Task.WaitAll(uploadIconTask, uploadLogoTask); // never returns

和Task.WaitAll永远挂起!

问题是什么？!
