您好，

您是说您使用appdata保存了设置并且商店已清除您的设置吗？ https://docs.microsoft.com/en-us/windows/uwp/design/app-settings/store-and-retrieve-app-data 

如果你是文件使用本地应用程序数据应该执行此操作"系统还会在用户安装应用程序更新时保留这些数据存储的内容，并在卸载应用程序时完全干净地删除这些数据存储的内容。" 

如果您没有在桌面应用中使用此API，我建议您使用UWP应用程序存储它并测试结果。

还有一个可能相关的注释：

关于应用数据的重要说明：应用数据的生命周期与应用的生命周期相关联。如果删除该应用，则所有应用数据都将丢失。不要使用应用数据存储用户数据或用户可能认为有价值的任何内容
且无法替代。我们建议使用用户的库和Microsoft OneDrive存储此类信息。应用数据非常适合存储应用特定的用户偏好，设置和收藏。

祝你好运，

I have a desktop bridge application published to the store. Whenever I enable an update for it, the update clears the application settings, such as the color scheme the user chose. It didn't do this for the first few updates, but now it is. How can I enable a new submission without clearing out the settings of the application?

I'm using My.MySettingsProperty.Settings.

Hello,

Do you mean you've saved your settings using appdata and the store cleared your settings? https://docs.microsoft.com/en-us/windows/uwp/design/app-settings/store-and-retrieve-app-data 

Per the doc if you use local app data it should do this "The system also preserves the contents of these data stores when the user installs an update to your app and removes the contents of these data stores completely and cleanly when your app is uninstalled." 

If you haven't used this API from your desktop app, I recommend that you store it using the UWP app and test the result.

There is also a note which might be related:

Important note about app data: The lifetime of the app data is tied to the lifetime of the app. If the app is removed, all of the app data will be lost as a consequence. Don't use app data to store user data or anything that users might perceive as valuable and irreplaceable. We recommend that the user's libraries and Microsoft OneDrive be used to store this sort of information. App data is ideal for storing app-specific user preferences, settings, and favorites.

Best regards,

Barry
