This paper delves into the common "inconsistent accessibility" error in C# programming, particularly focusing on compilation issues that arise when the accessibility of a property type is lower than that of the property itself. Through a detailed case study—where the Delivery class is not declared as public, causing an error in the thelivery property of Form1—the article explains the rules of C# accessibility modifiers and their significance in object-oriented design. Based on the best answer's solution, we demonstrate how to fix the error by declaring the class as public, and further discuss related concepts such as internal classes, property encapsulation, and namespace scope.
