'For Each' on type '<typename>' is ambiguous because the type implements multiple instantiations of 'System.Collections.Generic.IEnumerable(Of T)'
A For Each statement specifies an iterator variable that has more than one GetEnumerator method.
The iterator variable must be of a type that implements the System.Collections.IEnumerable or System.Collections.Generic.IEnumerable<T> interface in one of the Collections namespaces of the .NET Framework. It is possible for a class to implement more than one constructed generic interface, using a different type argument for each construction. If a class that does this is used for the iterator variable, that variable has more than one GetEnumerator method. In such a case, Visual Basic cannot choose which method to call.
