我正在使用 Xamarin Forms 开发一个带有 SignalR 的消息发送应用程序，我在本地和 Android 上测试了无数次，它运行良好，没有崩溃，但是当他们进行测试以将其上传到微软商店时，他们报告说我的应用程序崩溃了。
根据应用程序中心，应用程序在尝试通过 SignalR 发送消息时崩溃，这是错误：

System.Reflection.MissingMetadataException: 无法执行此操作，因为出于性能原因删除了以下对象的元数据:\n\n EETypeRva:0x0035FCD8\n\n没有可用的进一步信息。在调试模式下重建以获得更好的信息。\n\n

如果有人可以给我任何关于如何确定错误的提示或建议。谢谢。
附：我也尝试过上传调试符号，但我认为应用程序中心页面存在错误，或者我可能做错了什么，问题是在尝试上传大约 20 分钟后，页面被清理，并且没有上传任何内容，此过程我已经尝试了 7 次，但从未成功上传 .appxsym
