I'm not trying to change the struct, I'm try to change the departmentId.

ECMA 334, §14.5.4 Member access:

... if E is a property or indexer access, then the value of the property or indexer access is obtained
(§14.1.1) and E is reclassified as a value.

ECMA 334, §18.3.3 Assignment:

When a property or indexer of a struct is the target of an assignment, the instance expression associated with
the property or indexer access shall be classified as a variable. If the instance expression is classified as a
value, a compile-time error occurs. This is described in further detail in §14.14.1.

public class Employee

    private Department _TheDepartment;
    public Department TheDepartment

        get { return _TheDepartment; }
        set { _TheDepartment = value; }
        }

public struct Department
