使用 Visual Studio 2015 调试 WPF 应用程序时出现 XamlParseException

Question

我正在开发一个曾经使用 VS 2012 进行调试的 WPF 应用程序。 自从我切换到 Visual Studio 2015 后，我无法再对其进行调试。在运行时我得到 System.Windows.Markup.XamlParseException 并且应用程序崩溃。 需要注意的是，编译的可执行文件在通过双击其图标启动时可以正确运行。我什至可以在 VS 2015 中调试它，方法是在启动后附加进程。

在我的应用程序中，我使用了 xceed.wpf.toolkit。

例外是：

System.Windows.Markup.XamlParseException occurred
  HResult=-2146233087
  LineNumber=58
  LinePosition=15
  Message='Initialization of 'Xceed.Wpf.Toolkit.BusyIndicator' threw an exception.' Line number '58' and line position '15'.

            InnerException: 

另请注意，所涉及的组件 Xceed.Wpf.Toolkit.dll（在正确版本 v2.1.0.0 中）存在于输出目录中，靠近应用程序的编译可执行文件。

有什么建议可以让应用程序使用 VS 2015 集成调试器工作？

谢谢！

Answer 1

您可能需要检查this

并使用pack:... 语法。

原来 Toolkit 中存在一个问题，它只会在 VS2015 中出错，而在以前的版本中不会出错。 仍然需要了解最新版本和以前版本的 VS 之间的差异，但至少这个补丁有效。

我禁用了

调试 |一般 |为 XAML 启用 UI 调试工具

选项，一切又开始工作了。
