How to create your own library?

Question

WPF

Hello.
I want to create my own library to implement Gantt Chart.

I'm going to implement all this through the ItemsControl set in Generic.xaml.
Those. ItemsControl for the first group of columns, ItemsControl for the value columns of the charts themselves (dates) and the ItemsControl itself for the rows (the implementation of the columns is already ready, more torment with the ScrollView to fit all this on the screen).
I don't know if my approach is correct. I'm not looking for a ready-made solution, so I ask you, on my own or someone else's experience, to suggest how best to create such libraries or in which book you can learn this.
Thank you.

The question doesn't make much sense. Closed)

Answer 2

If the question is about creating a library, and not a GUI, then from my own experience - the entire diagram is placed in the UserControl. How you place it there is up to you. One subtlety - before using the UserControl - build the project, otherwise this control will not be picked up even in the original project.
