Code inspection: Not accessed primary constructor parameter

This inspection reports a primary constructor parameter that is declared but never accessed. In practice, this usually means the parameter should either initialize state or be removed.

Example

class Person(string name, int age)
{
    public string Name { get; }
}
            

class Person(string name, int age)
{
    public string Name { get; } = name;
}
            

Quick-fix

The quick-fix initializes a property or field with the constructor parameter, or remove the unused parameter.
