WinForms or WPF: Who project choosing?

My cordial greetings peoples of the night.
I have an idea of developing a personal software, equivalent to Xsplit Broadcaster. It will be definitively very extensible and to summarize, I want to add the combination of all the alternatives of broascating/screencasting software.

What do type of project recommend me to start with?
WinForms or Windows Presentation Fundation?

The IDE is Visual Studio Pro 2015, obiously.

Hi Skylär,

I’m sorry Nsight is a developer tool, maybe you need to go to other forum for your confusion.
