Notes to Inheritors
The base implementation includes a call to the internal helper ThrowIfUnknown. This helper always throws for cases where a XamlMemberInvoker is based on an unknown XamlMember, which includes cases where the UnderlyingMember of the XamlMember is null.
The base implementation throws if UnderlyingSetter is null.
For static properties (IsStatic is true per UnderlyingSetter) the default implementation calls Invoke(Object, Object[]) on UnderlyingSetter passing null as the first parameter and packaging instance and value as the second parameter. For non-static properties, it calls Invoke(Object, Object[]) and forwards instance as first parameter and value as second parameter.
