But yeah, I would have to agree that there's definitely a "hole" in the BCL where a read-only indexed collection interface should go. IList is just too multi-purpose.

In programs, an immutable collection güç be used with less copying—we do hamiş need to worry about it being modified. This kişi make programs simpler and easier to reason about.

I avoid using ReadOnlyCollection kakım much kakım possible, it is actually considerably slower than just using a uygun List.

Sum(IEnumerable, Func) Computes the sum of the sequence of Decimal values that are obtained by invoking a transform function on each element of the input sequence.

Sum(IEnumerable, Func) Computes the sum of the sequence of Int32 values that are obtained by invoking a transform function on each element of the input sequence.

Anyway, I believe that a domain object should be read-write, because at the end of the day, a domain object describes an entity within the domain and you should be able to access and modify it.
