What i know so far about how to code for win 7 taskbar features is that i can either use .net 4 or WinAPI code pack in .net3.5 or pinvoke.
My question is that can i code for win 7 task bar features using .net3.0 or prev and using pinvoke can i use features such as thumbnail toolbar, jumplist, overlay icon
Thanks
Why not get hold of the Code Pack and try using it with a lower version of the .NET Framework? I have read a lot of the code in there and little if any of it relies on .NET 3.5 features. If you're using VS 2010 you could probably succeed in building it against 2.0 or whatever you're using no problem. The license allows you to integrate code from the library into your project, to change it, to basically treat it as your own, so you've got nothing to lose.
