Question

无法加载参考程序集以执行

这是我调试/编译项目时获得的唯一信息。该项目编译和运行，我可以使用我添加的功能没有问题。错误发生在Page.Datacontext上，我在那里定义了在该页面上使用的viewmodel，对于我拥有的两个页面，它是相同的。

这是错误

这是错误的地方

它也发生在我的另一个项目中，我尝试调试/寻找帮助，但我无法弄清楚如何解决它。我的程序集中似乎有64 / 32bit冲突的问题。所以我从另一个项目开始，看看我是否可以修复它，它可以工作很长一段时间。我不明白这个错误是如何在我的第二个项目中出现的。我只是尝试做一些xaml绑定，我复制了一些代码位，没有工作，所以我把它拿出然后错误来了。该项目仍然建设和工作，＆＃34; Buld成功＆＃34;但错误仍然存在。

当我测试更多时，如果我将viewmodel更改为MainPageViewModel，我就不会收到错误。我正在使用模板10汉堡包
