Proxy Design Pattern in C#

The proxy design pattern adds an extra layer of control over access to an object through a wrapper object (proxy) that acts on behalf of the original object (real subject). This pattern allows additional logic without modifying the original object's functionality. Use cases include caching, logging, protection, remote services, and conditional service resolution. While the pattern offers multiple benefits, it introduces complexity and potential maintenance overhead, particularly with asynchronous or multithreaded operations.
