Introduction to C#

Definition

C# (pronounced "C-sharp") is a modern, object-oriented programming language developed by Microsoft. It was first released in 2000 as part of the .NET framework, and it is designed to be used for building a wide range of applications, from simple command-line programs to complex, enterprise-level applications. C# is a type-safe, managed language, meaning that the runtime environment automatically handles memory management and other low-level details, allowing developers to focus on writing code. C# is a statically-typed language, meaning that types are checked at compile-time rather than at runtime. This makes C# programs more efficient and less prone to runtime errors.
