所以我刚刚开始使用这些东西并遇到了一些冲突。我需要将一个转轴音板应用程序转换为一系列全景页面，但具有相同的功能。
我已经完成了所有的xaml和c＃，但我认为因为我必须创建一个新的MainPage并删除旧的我创建了几个错误。我怀疑他们都有类似的原因，所以我只提供三个。
错误1类型＆＃39; SoundBoard.MainPage＆＃39;已经包含一个定义 对于＆＃39; LayoutRoot＆＃39; \音板\ OBJ \调试\ Cartoons.g.cs
错误30名称＆＃39; AudioPlayer＆＃39;在当前不存在 context \ SoundBoard \ Cartoons.xaml.cs
错误7键入＆＃39; SoundBoard.MainPage＆＃39;已定义一个名为的成员 ＆＃39;的InitializeComponent＆＃39;具有相同的参数类型 \音板\ OBJ \调试\ Cartoons.g.cs
我将链接我当前的主页和漫画，希望你们能帮助我。

正如我所说，它可能是愚蠢的但我真的被卡住了所以非常感谢任何建议。

似乎所有问题都存在于自动生成的文件Cartoons.g.cs中。指向非完全自动生成的文件的唯一错误是：
The name 'AudioPlayer' does not exist in the current context \SoundBoard\Cartoons.xaml.cs
当它存在时，抱怨AudioPlayer不存在，在Cartoons.xaml中声明。这就是所有奇怪的错误。
我要做的第一件事是清理（从visual studio，或手动删除bin和debug文件夹）并重建项目，甚至重新启动Visual Studio。这些步骤可以在大多数时间修复奇怪的错误。

问题是Cartoons.xaml和MainPage.xaml都有相同的行x:Class="SoundBoard.MainPage"。我不确定，但认为Cartoons.xaml应该对x:Class属性具有不同的值
