Users of the Microsoft Dynamics NAV Windows Client are suddenly running into error messages about a Document Creator assembly or file not being found. What can we do about this? We are using Document Creator from a Docker container, but it does not use the correct fonts. What is causing this and what could we do about this? What is the syntax we can use for expressions (e.g., for the VisibleExpression property)? Is Document Creator (support) future proof? How about a Classic Report and RDLC Report Layout Converter?
