    Class NullAchievementScreenshotStore

    The screenshot store installed when nothing can hold the bytes: it stores nothing and hands back no key, so the unlock record simply carries no screenshot.

    Syntax
    public sealed class NullAchievementScreenshotStore : IAchievementScreenshotStore
    Remarks

    Pairs with NullAchievementScreenshotCapturer: the attachment collaborator requires both a capturer and a store, so a project with no capture support still needs a store instance to construct one. Keeps the unlock path free of null checks.
