c# - 尝试在 Visual Studio 2008 中编辑 UI 时出现 WPF Designer 异常

Question

我的机器上安装了带有 .net 3.5 SP1 的 VS2008，我编写了一个带有两个 ListView 和数据绑定(bind)的简单应用程序，我的应用程序编译正常并且能够运行它，但是当我尝试打开设计器来编辑控件时，我收到以下错误。 我不明白为什么会这样。任何想法...请参阅此错误消息下方的 xaml

Answer 1

我已经使用 .NET 3.5 SP1 在 VS2008 中测试了您的代码，如果我删除了 TrinityDeviceTree 的声明，它可以与设计器一起正常工作。 也许您应该查看该 UserControl 并在那里查找错误。还要尝试清理您的项目并重新构建，有时它可以解决视觉设计师的问题。
