Is it possible to get a screen capture in a Windows 8 metro app?
Well there might be some issues with the current release version, actually I don't remember if it worked correctly.
But the current unstable, which can be downloaded here works a lot better.
There is still an issue when having multiple monitors though, it's a bit of a problem finding enough information with Microsoft.
With our 1.1 which is hitting the release candidate phase it works a lot better.
