Context: I'm creating some applications to help me on my daily tasks, it does not connect anywhere and the only "data" it has to deal with is the parameters that I enter on the input fields.

This is how I structured my solution:

|- Helpers (Folder + Class Library)
|- Domain (Folder + Class Library)
|- Shared (Folder + Shared project)
|- Apps (Folder + WPF Projects)
|---- App1 (WPF Project)
|---- App2 (WPF Project)
|---- App3 (WPF Project)

While developing the first application (App1) I've created a few UserControls. Now I want to use those user controls on the second application (App2).

Question is: Should I create a new WPF Project to hold all these UserControls and reference it from App1, App2 and App3? If not, what should I do?

Additional info: I'm using MVVM.

Ps: Please know that I'm a student, so it'd be nice if the answers contain a start point, or some of the advantages and disadvantages of each approach, so I can learn them better.

Thank you!
