I have a winforms app but I would like to introduce a WPF user control into the app as a taster for further WPF implementation.
This control needs to receive from its Host a single piece of information, a string. How can I pass this down from the Winforms app to the hosted control?
Or, indeed, can I?
It is possible. Extend your WPF User Control with methods to set whatever data you want and call them from within WinForms application. See this article for example.
