Remarks

Helper class for treating a collection of a derived type as a collection of a base type or interface.

LCExt.UpCast{T, TResult}(IReadOnlyCollection{T})

This class is rarely needed because generic variance allows casting IListSource{DerivedClass} to IListSource{BaseClass}. However, it is still useful to convert a list of structs from IListSource{Struct} to IListSource{IInterface}.
