推荐答案
当我了解您有一个AppService，用于从语音命令激活应用程序并使用AppService主机的进程外后台任务。您可以修改您的AppService来托管它的进程内后台任务，并在App
类OnBackgroundActivated方法中处理您想要的内容。第二种方式，如果您不想修改您的语音AppService，那么您可以使用进程内托管创建新的AppService并将其用于通信。
As I understand you have an AppService for activation the app from voice command and using Out-of-Process background task for the AppService host. You can modify your AppService to host it In-Process background task and handle what you want in App class OnBackgroundActivated method. The second way if you doesn't want modify your voice AppService then you can create a new AppService with In-Process hosting and use it for communication.
