即使在GAC中安装了组件，该方法或操作也未实现异常

Question

我遇到了WPF的问题，即程序集的早期版本已加载到我的应用程序中，所以我们说一个Xceed.WPF.Toolkit而不是v.2.0。我正在编写此应用程序的扩展程序，该程序需要较新版本的工具箱（例如v.3.4）。

我认为，在安装该应用程序的插件时，该插件向基本应用程序添加了额外的功能，如果我将新的Xceed v.3.4添加到GAC，它将能够使用该应用程序中提供的新控件来解析XAML。组装，一切都会好的。但是，我一直得到这个：

我的程序集显然已安装在GAC中：

是否有一种方法可以使我缺少的通过GAC发现新的装配体版本？

我曾在调用WPF Assembly.LoadFrom()之前尝试使用InitializeComponent();，但即使程序集加载正常，初始化时它仍会引发XAML异常。

任何想法都会受到赞赏。

编辑：

谢谢您使用汇编绑定日志查看器的建议。我能够从中提取以下日志。加载Xceed工具箱时的主应用程序将使用以下日志绑定到3.0版：

然后是我的扩展程序尝试使用以下日志加载3.4版本：

谁能帮助我理解这些含义？
