Is that possible? I know that services like Google Ads prohibit advertising in desktop applications. Is there a service that supports the WPF/.NET?
First,adsense being not allowed to be used in desktop apps , You can look for other advertising networks. There are other ad networks like amazon associates , .. etc . You can search for them according to the domains ex: banking, retails . You can look for/contact them for their terms and conditions on desktop usage.
And not all of them would provide you an API for .Net. If amazon is allowed for desktop usage: Look into this API
Secondly , w.r.t the technical aspects of WPF. You can have a website built to inject ads from your network . Embed the URL in the web browser control in your WPF applications. This would work on condition that the desktop is connected to internet all the time.
In case if all doors are closed , and you still want to make money from your wpf app , you can think about using toolbars provided by various vendors in your application.
Hope this helps.
