Do you have exposure to C# 1.0 and C# 2.0?

Yes, I have worked with both C# 1.0 and C# 2.0. In C# 1.0 I built console applications and simple Windows Forms using basic object‑oriented principles. With C# 2.0 I leveraged generics to create type‑safe collections, used iterators to simplify data traversal, and employed partial classes to split large codebases across multiple files. These features allowed me to write cleaner, more maintainable code and improved performance by eliminating boxing and unboxing overhead.
