Immutable views of mutable types

Question

Why can't you provide a separate immutable view of the object?

public class ImmutableConfiguration {
    private Configuration _config;
    public ImmutableConfiguration(Configuration config) { _config = config; }
    public string Version { get { return _config.Version; } }
}

or if you don't like the extra typing, make the set members internal rather than public - accessible within the assembly but not by clients of it?
