Question

我需要显示来自插件（单独的DLL库）的数据模板。我启发了here。

这是我的源代码：

Plugin.cs

public class Plugin
{
  private ResourceDictionary ViewTemplate { get; set; } = new ResourceDictionary();

 private object ViewModel {get; set;}

  public Plugin(){
    ViewTemplate = new Uri("PluginExample;component/View.xaml", UriKind.RelativeOrAbsolute);
    ViewModel = new ExampleVm() {Title = "Example"};
  }

  public Result GetResult()
  {
     return new Result()
     {
       Content = new Content() { Template = ViewTemplate, ViewModel = ViewModel};
     }
  }
}

View.xaml

<ResourceDictionary>
  <DataTemplate DataType="{x:Type vm:ExampleVm}">
    <TextBlock Text="{Binding Title}" Background="Red"/>
  </DataTemplate>
</ResourceDictionary>

ApplicationVm

public ApplicationVm()
{
   var result = Plugin.GetResult();
   Application.Current.Resources.MergedDictionaries.Add(result.Content.Template);
  ResultVm = result.ViewModel;
}

ApplicationView

 <ContentControl Content="{Binding ResultVm}" />

启动应用程序时，将显示Namespace.ExampleVm。正确的解决方案必须是绑定了ExampleVm.Title =“ Example”的TextBlock。在哪里可以解决问题？如何从插件显示DataTemplate？谢谢
