Have someone tried to include custom control on a form , pack this form and custom control into a solution, and then deploy this solution to another environment?
If so, did you see the control on the form in the model driven app?
In our case, we weren't able to see the control (import and everything went fine, but it wasn't displaying on the form).
Any ideas? Does the control need to be included in the model-driven app somehow? I'll try to look more into it and post updates here.
Thanks!
