WPF开发(插件管理、tab切换)

在主界面框架中，我们依靠第三方控件库"ModernUI"来实现界面，并对"ModernUI"做深入的定制。在界面框架插件引用该控件时，首先，我们需要将该插件添加到Manifest.xml作为本地程序集，即界面框架插件在运行时需要与该程序集一起才能够正常运行。

1. var bundleRuntime = new BundleRuntime();
2. bundleRuntime.AddService();
3. bundleRuntime.Start();

注意：主程序在BundleRuntime.Start方法调用前注册的服务，插件在启动时即可获取。这时候，插件可以在激活器中直接获取到该服务了。

1. public class Activator : IBundleActivator
2. {
3. public void Start(IBundleContext context)
4. {
5. var sayHelloService = context.GetFirstOrDefaultService();
6. sayHelloService.Hell("Lorry Chen");
7. }
8. public void Stop(IBundleContext context)
9.     {
10.     
11.     }
12. }
