All of a sudden, I am not able to open Package.appxmanifest.

There is no editor available for 'D:\Build\vs\UwpTest\UwpTest\Package.appxmanifest'.
Make sure the application for the file type (.appxmanifest) is installed.

    Hello @杨岑,

    I think something’s wrong with this specific file(.appxmanifest) or with VS.

    A temporarily quick workaround is to create a new UWP project, edit its .appxmanifest file to match your project’s .appxmanifest file and replace your .appxmanifest file. Don’t just copy and paste the xml code. It’s possible that there are some bad characters in the .appxmanifest file, if you just copy and paste the xml code, this issue may persist.

    If this doesn’t work, please try to repair VS from VS Installer => More => Repair.

    Best Regards,

    Tianyu
