C# stands as a contemporary, flexible, and object-oriented programming language. Microsoft introduced it in 2000 within the .NET Framework, empowering programmers to build software for various operating systems such as Windows, macOS, and Linux. Its characteristics align it with languages such as C++ and Java.
In January 1999, Anders Hejlsberg formed a group to work on a fresh programming language initially known as Cool, representing "C-like Object Oriented Language". Microsoft decided on "Cool" as the language's official name, but opted against it due to trademark concerns. This decision was made by the time the .NET initiative was officially revealed to the public in July 2000.
After a period of time, C# has evolved further by incorporating additional functionalities, enhancing its efficiency and ease of maintenance for software developers. This programming language is widely employed for developing a variety of applications such as desktop programs, web applications, mobile apps, games, cloud services, and more.
Origins of C#
C# was created by Microsoft led by Anders Hejlsberg, a renowned software developer with experience in projects like Turbo Pascal and Delphi. He spearheaded a group at Microsoft during the development of the .NET Framework.
The CSS code snippet provided below illustrates the styling for a historical timeline diagram on a web page:
.history-diagram { background: linear-gradient(135deg, #1e3a5f 0%, #0d1b2a 100%); border-radius: 12px; padding: 25px; margin: 20px 0; }
.history-diagram .diagram-title { text-align: center; color: #60a5fa; font-size: 1.2rem; font-weight: 600; margin-bottom: 20px; }
.history-diagram .timeline { display: flex; justify-content: space-between; flex-wrap: wrap; gap: 10px; position: relative; }
.history-diagram .timeline::before { content: ''; position: absolute; top: 20px; left: 0; right: 0; height: 3px; background: linear-gradient(90deg, #3b82f6, #8b5cf6); z-index: 0; }
.history-diagram .timeline-item { flex: 1; min-width: 100px; text-align: center; position: relative; z-index: 1; }
.history-diagram .year { background: #3b82f6; color: white; padding: 5px 10px; border-radius: 15px; font-size: 0.8rem; font-weight: 600; display: inline-block; }
.history-diagram .version { color: #60a5fa; font-weight: 700; margin: 10px 0 5px; }
.history-diagram .desc { color: #94a3b8; font-size: 0.75rem; }
Anders Hejlsberg initiated the creation of the C# programming language back in 1999. Originally named Cool (C-like Object Oriented Language), Microsoft later rebranded it to C-Sharp (C#) before launch. C# stands out as a contemporary and high-speed programming language that integrates various functionalities from languages like C++ and Java.

After the inception of C#, it has undergone numerous iterations, with each release introducing additional functionalities to enhance the ease and security of programming. C# has seen several iterations, including the following:
The CSS code snippet provided above defines the styling for a historical timeline diagram. The diagram is set with a gradient background, rounded corners, padding, and margin. The title of the diagram is centered with a specific color, font size, and weight. The timeline itself is structured using flexbox properties for spacing and alignment. Each timeline item includes a year marker with a colored background, version information, and a description. Additionally, a horizontal line is drawn across the timeline for visual separation.
C# 1.0 (January 2002)
The initial iteration of the C# programming language debuted in January 2002, accompanying the .NET Framework 1.0 and Visual Studio .NET 2002. Microsoft developed it as a contemporary, adaptable, and object-oriented language. This release incorporated various functionalities like type-safety, exception handling, and garbage collection. Furthermore, fundamental components such as classes, structs, interfaces, and properties were also introduced to support the construction of .NET applications.
C# 2.0 (November 2005)
The 2005 release of C# brought forth numerous enhancements such as the inclusion of generics to ensure type safety, partial classes for dividing class definitions, anonymous methods for inline functionality, and nullable value types for handling null values. Additionally, it introduced iterators through the use of yields and extended support for covariance and contravariance in delegates. These additional functionalities significantly enhanced the flexibility and potency of the language.
C# 3.0 (November 2007)
