Exceptions

Notes to Inheritors

The base implementation includes a call to the internal helper ThrowIfUnknown. This helper always throws for cases where a XamlTypeInvoker is based on an unknown XamlType, which includes cases where the UnderlyingType of the XamlType is null.

The base implementation does not necessarily use its own GetEnumeratorMethod() implementation. First, a cast of instance to IEnumerable is attempted. If this succeeds, a call to GetEnumerator() is made and the method returns that return value. Otherwise, the base implementation uses CLR Invoke(Object, Object[]) to invoke the underlying GetEnumerator method, as obtained from a call to GetEnumeratorMethod() for this XamlTypeInvoker.
