Code inspection: 'params' modifier is always ignored on overrides

This inspection reports the params modifier when it is ignored and has no effect. A common case is an override where the base declaration does not use params.

Example

class A
{
    public virtual void Foo(object[] args)
    {
    }
}
class B : A
{
    public override void Foo(params object[] args)
    {
    }
}
            

class A
{
    public virtual void Foo(object[] args)
    {
    }
}
class B : A
{
    public override void Foo(object[] args)
    {
    }
}
