我正在开发一个应用程序的插件。我的插件使用 WPF Toolkit 1.6.0.0。WPF Toolkit 程序集是强命名的，我确保我对程序集的所有引用都是特定版本的。

宿主应用程序使用以前版本的 WPF Toolkit (1.5.0.0)。当我的插件尝试加载 WPFToolkit 时，它会从主机应用程序加载版本，即使正确的程序集与我的插件程序集位于同一文件夹中（我从该文件夹加载其他依赖项没有问题）。

如何确保加载了正确版本的库？

我仍然不知道为什么会遇到这个问题，但我找到了解决方法。通过连接AppDomain.CurrentDomain.AssemblyResolve并手动加载程序集，我能够正确加载程序集。

这是解析器的代码：

private static Assembly HandleAssemblyResolve(object sender, ResolveEventArgs args)
{
    Assembly requestingAssembly = (args.RequestingAssembly ?? Assembly.GetExecutingAssembly());
    AssemblyName assemblyName = new AssemblyName(args.Name);

    string currentLocation = requestingAssembly.Location;
    string baseDirectory = Path.GetDirectoryName(currentLocation);
    string assemblyLocation = Path.Combine(baseDirectory, assemblyName.Name + ".dll");

    if (File.Exists(assemblyLocation))
    {
        return Assembly.LoadFile(assemblyLocation);
    }

    return null;
}
