Somasegar also goes into detail about how .Net will carry forward to the new platform:
With Windows 10, all .Net apps will be compiled with .Net Native by the Windows Store before being delivered to devices... Windows 10 also comes pre-installed with .Net Framework 4.6 which includes many new features including improvements in WPF and Windows Forms.
To get up and running, first make sure you're completely up to date with Windows 10 Tech Preview build 10041. You'll also need Visual Studio 2015 Community Tech Preview (CTP) 6, which was released last month, as well as the new Tools for Windows 10 Technical Preview. Full instructions are on the Windows dev site.
Microsoft already has sample code posted on GitHub.
