在 Visual Studio 调试器扩展中使用 OxyPlot

Question

我正在尝试在 VS 调试器扩展 (WPF Xaml UserControl) 中使用 OxyPlot 库，但是，即使是最简单的示例也失败了。在控件构造函数中调用 InitializeComponent 会抛出如下异常：

System.Windows.Markup.XamlParseException occurred
HResult=0x80131501
Message=Could not load file or assembly 'OxyPlot.Wpf, PublicKeyToken=75e952ba404cdbb0' or one of its dependencies. The system cannot find the file specified.

OxyPlot 程序集正确包含在扩展部署文件夹中。 OxyPlot 的示例应用程序都可以正常工作，因此它似乎与 VS 调试器扩展以及如何解析程序集有关。

XAML 命名空间声明是：

xmlns:oxy="clr-namespace:OxyPlot.Wpf;assembly=OxyPlot.Wpf"

而在一些 (XAML) 示例中，我还看到：

xmlns:oxy="http://oxyplot.org/wpf"

该 URL 解析为 404，并尝试编译我得到：

error MC3074: The tag 'PlotView' does not exist in XML namespace 'http://oxyplot.org/wpf'. 

但是，OxyPlot 包中的 WPF 示例使用相同的命名空间声明没有问题？

更新：问题的融合日志，很明显，程序集加载器找不到 OxyPlot.Wpf.dll，尽管 DLL 在安装的 VS 扩展的位置（在 C:\Users\\AppData\ Local\Microsoft\VisualStudio\14.0Exp\Extensions\Adam Wulkiewicz\GraphicalDebugging\0.7)：

想法？

Answer 1

好的，我不是一个精通 .NET 的人，我感谢 Palle Due 的解决方案，在我添加的扩展包构造函数中：

AppDomain.CurrentDomain.AssemblyResolve += new ResolveEventHandler(CurrentDomain_AssemblyResolve);

然后在处理程序中：

private Assembly CurrentDomain_AssemblyResolve(object sender, ResolveEventArgs args)
{
    return AppDomain.CurrentDomain.Load(args.Name);
}

它很好地加载了 OxyPlot。唷。
