This should be a simple 100-level question, but I\'m seeing something I don\'t expect in my project, and web searches have failed me, so I thought I\'d ask here. Suppose I have the following C++ code:
I\'m currently working on a C# project where a main base form is derived by several other forms. Im using an entity class to handle data manipulation for every entity represented in the system: items,
