I finally managed to get around to downloading and installing the preview release of Windows 10 - which includes Microsoft's replacement for Internet Explorer, Edge.
I gave the Adapt v2.0.0 framework preview release a quick run through in the Edge preview release - good news: everything works fine. The only issue I could find was a slightly misaligned block background image in co-05.
The new theme in particular looks great on Windows 10, it really matches the Windows UI nicely.
Whilst this is good news, it is just a quick test in a preview release. Further testing will need to be done when Windows 10 is actually released (29th July) - particularly across devices as the main selling point of Win10 is that it's one OS for all your devices, so no more Window RT or Windows Phone.
