In visual studio I defined some content types. In addition I added each content type to a list definition and created a list instance from each list definition. When I install my solution in SharePoint I get no errors and all list instances and content types are there. But when I want to add a new item to one of this list instances I can see just “New Item” and my corresponding content type doesn’t appear in UI for selecting. When I show In list setting the content type columns are there and in all list forms appears in correct format.
Where can I have made a mistake?
