I can build the solution but cannot run the solution via Live Player. 我可以构建解决方案，但不能通过Live Player运行该解决方案。 This error happened after I create sub-folder in my project and move some XAML file into that folder. 在项目中创建子文件夹并将某些XAML文件移动到该文件夹后，就会发生此错误。 I've already Clean & Rebuilt, Manually delete /obj and /bin folders, and re-install Visual Studio and Xamarin. 我已经清理并重建了，手动删除/ obj和/ bin文件夹，然后重新安装Visual Studio和Xamarin。 What should I do to solve this problem, please help. 我应该怎么做才能解决这个问题，请帮忙。 Thanks! 谢谢！
