History of C#
C# was developed by Microsoft in the late 1990s and early 2000s, under the leadership of Anders Hejlsberg, who is known as the father of C#. C# was influenced by several languages, such as C, C++, Java, Delphi, etc. C# was first released in 2002, along with the .NET Framework 1.0. Since then, C# has evolved through several versions, each introducing new features and enhancements.
The following table shows the history of C# versions and their features:

C# 9.0 | 2020 | Record types, init-only properties, top-level statements, pattern matching enhancements, target-typed new expressions, covariant return types, etc. |
C# 10.0 | 2021 | Record structs, global using directives, file-scoped namespaces, extended property patterns, constant interpolated strings, etc. |
The C# programming language was developed by Microsoft in the year 2000 under the leadership of Anders Hejlsberg as part of the .NET Framework. It was designed to be simple, modern, and object-oriented, combining the best features of C and C++. Over the years, C# has undergone several improvements and additions, including support for modern programming paradigms like LINQ, async/await, and pattern matching.
C# has evolved significantly since its inception:
- C# 1.0 (2002): Initial release with basic object-oriented features.
- C# 2.0 (2005): Introduced generics, nullable types, and anonymous methods.
- C# 3.0 (2007): Added LINQ, extension methods, and object initializers.
- C# 4.0 (2010): Introduced dynamic typing and improvements to COM interop.
- C# 5.0 (2012): Introduced async/await for asynchronous programming.
- C# 6.0 (2015): Focused on improving code simplicity and syntax, such as expression-bodied members.
- C# 7.0 – 8.0 (2017-2019): Introduced new features like default literal, local functions, and nullable reference types.
- C# 9.0 – 10.0 (2020-2022): Continued improvements, including records, init-only properties, and global using directives.
The C# language has evolved with each new version adding features aimed at improving performance, code readability, and developer productivity. Key milestones in its evolution include:
- Introduction of generics in C# 2.0, allowing for type-safe data structures.
- The addition of LINQ in C# 3.0, enabling SQL-like querying in C#.
- The introduction of asynchronous programming with async/await in C# 5.0.
- Modern features like records, pattern matching, and source generators were added in later versions, helping developers write more concise and efficient code.
Each version of C# brought new features and enhancements:
- C# 1.0: Basic object-oriented language features.
- C# 2.0: Introduced generics and nullable types.
- C# 3.0: Added LINQ, automatic properties, and extension methods.
- C# 4.0: Focused on dynamic typing and interop with COM.
- C# 5.0: Introduced async/await for handling asynchronous programming.
- C# 6.0: Simplified syntax and improved code readability.
- C# 7.0+: Introduced features like local functions, tuple types, and default literal.
- C# 9.0 – 10.0: Focused on records, pattern matching, and nullability annotations.
Each version built on the foundation of C#, enhancing the language’s capability to meet modern development needs.
Some of the key milestones in the history of C# include:
- 2000: C# was first introduced by Microsoft.
- 2002: C# 1.0 was released as part of the .NET Framework.
- 2005: C# 2.0 introduced generics.
- 2007: C# 3.0 brought LINQ.
- 2010: C# 4.0 added dynamic typing.
- 2012: C# 5.0 introduced async/await for asynchronous programming.
- 2015: C# 6.0 introduced simplified syntax.
- 2020: C# 9.0 and records were introduced to enhance data handling.
- 2022: C# 10.0 further expanded global using directives and other modern features.
Each milestone has contributed to making C# one of the most powerful and developer-friendly languages.
C# became popular due to its simplicity, modern features, and powerful integration with the .NET Framework. It was designed to be easy to use and capable of building various types of applications, from web to desktop to mobile apps. Over time, Microsoft’s continuous updates and community-driven features have contributed to its widespread adoption in enterprise environments and the software development community.
