我正在尝试启动并运行 iBoxDb，但是，当尝试打开连接时，我得到 ArgumentNullException。完全相同的代码在 Windows Phone 8.1 Silverlight上运行良好，但在 WP 8.1运行时不运行。我尝试传递路径参数而不是""（的各种组合ApplicationData.Current.LocalFolder），但仍然没有。
由于 iBoxDb 几乎没有文档，我真的没有想法：|
编码：
...
private readonly AutoBox _db;
public iBoxDbRepository()
{
var server = new DB(1, "", true);
_db = server.Open();
}
...
堆栈跟踪：
