I need to make a multi touch application for a real state display centre. With buttons and maps and floor plans. And the application will be running on Windows 8.1 0 on a 42 inch screen. I want to know what would be the best technology to make this kind application ? Flash or WPF ?
Does Action script has events for the buttons ?
If it's going to be on Windows 8.1 can you not do it as a Metro/Modern app? The support for multi-touch will be a lot better than it is in WPF I think.
There's some information here on how you can approach different app categories.
Using the Windows 8 SDK will give you the opportunity to use JavaScript instead of C# if you find that easier too.
