Conclusion

Versioning is a fact of life for most developers. Designing code that versions well and handles changes to the libraries that it uses (including the .NET Framework libraries) can be a challenging task. Shadows and Overloads are intended to help developers deal with versioning.

A style point to consider is that the Overloads keyword is required only when you are doing overloading across the inheritance hierarchy. It is never required when you are doing overloading within a class.
