Navigation Section add-in Button error when i Build

Content

Hi,

When i try to add a custom add-in in the rightnow instance. Visual Studio show this error: "Cannot implicitly convert type 'AddinEntel.NavigationPanelButton' to 'RightNow.Addins.AddinViews.INavigationSection2'. An explicit conversion exists(are you missing a cast).

If anyone know how to solve this, please i will appreciate any help. Thanks.
