Info Tip is tooltip text for when the user hovers over a file of this type and the app is the primary
association. The Logo is a little tricky; in Visual Studio here, you simply refer to a base name for an
image file, like you do with other images in the manifest. In your actual project, however, you should
have multiple files for the same image in different target sizes (not resolution scales): 16x16, 32x32,
48x48, and 256x256. The Association launching sample uses such images with targetsize-* suffixes in the
filenames. 59 These various sizes help Windows provide the best user experience across many different
types of devices.

Under Edit Flags, these options control whether an “Open” verb is available for a downloaded file of
this type: checking Open Is Safe will enable the verb in various parts of the Windows UI; checking Always
Unsafe disables the verb. Leaving both blank might enable the verb, depending on where the file is
coming from and other settings within the system.
59 Ignore, however, the sample’s use of targetsize-* naming conventions for the app’s tile images; target sizes apply only to
file and URI scheme associations.
