Windows 8 with the new Metro UI is coming soon. We were working hard in the last weeks to port MatriX also to WinRT. Because WinRT is only a subset of the full .NET Framework and introduces many new techniques, namespaces and classes we had to rewrite lots of our code. We are happy to announce that a Beta version of MatriX for WinRT is available now.
Please contact us when you are interested at the beta version.
