When a developer builds a C# application, the source code is compiled into an intermediate language (IL) that conforms to the Common Language Infrastructure standard. The IL code and other application resources are stored in an assembly that is loaded into the CLR when the application runs. The CLR converts the IL code to native machine instructions using a just-in-time compilation process. The following figure shows the C# code for a simple console application as it appears in Visual Studio.
C# Features
The application adds together two integers that are entered by the user and then returns the total to the console. The CLR translates the IL code into native machine code, specific to the platform and architecture and it enables the program to run on different operating systems and devices. The C# compiler (csc) converts the source code into an Intermediate Language (IL). This IL is platform-independent and can be executed on any system that has the .NET runtime installed. For example, the Console class used later in the source code is defined in the System namespace, meaning it can be used without supplying the full name of the type (which includes the namespace). A unified type system implies that all types, including primitives such as integers, are subclasses of the System.Object class.

Data Analytics
C# is part of the .NET ecosystem, which allows us to write code that can be executed on different platforms. With .NET Core (now .NET 5 and beyond), C# code can now be run on platforms like Windows, macOS, and Linux, making it highly portable. A decade later, Microsoft began developing free, open-source, and cross-platform tooling for C#, namely Visual Studio Code, .NET Core, and Roslyn. Mono joined Microsoft as a project of Xamarin, a Microsoft subsidiary.
We’ll start with the basics like setting up your environment, C# syntax, and writing “Hello World” program, data types, and loops etc. After that we will start with advanced topics like object-oriented programming, delegates, tuples, indexers, collections, multithreading, and LINQ etc. It is an object-oriented programming language created by Microsoft that runs on the .NET Framework. Unlike C++, C# does not support multiple inheritance, although a class can implement any number of “interfaces” (fully abstract classes).
- The language, along with the .NET framework, can also be used to develop applications for systems running Linux, macOS, iOS or Android, although C# is used primarily to develop Windows applications.
- Development of the text for standards (beginning with C# 6) is done on GitHub.
- C# (pronounced “C-sharp”) is a modern, versatile, object-oriented programming language developed by Microsoft in 2000 that runs on the .NET Framework.
- Mono joined Microsoft as a project of Xamarin, a Microsoft subsidiary.
- Some operations are not always possible, such as creating an instance of a reference type, copying an existing instance, or performing a value comparison on two existing instances.
- C# is designed to work with Microsoft’s .NET platform, a software ecosystem for developing, compiling and running application code.
Advantages of C#
Development of the text for standards (beginning with C# 6) is done on GitHub. As of January 2024, the standard for C# 8 is currently under development, referencing the approved language proposals. Trevoir enjoys teaching IT and development skills and guides students in gaining the latest knowledge with practical application in the modern industry. We also look at troubleshooting and debugging errors to help you implement best practices, write efficient logic, and understand why developers do things the way they do. C# has roots from the C family, and the language is close to other popular languages like C++ and Java.
C# (pronounced “C-sharp”) is a modern, versatile, object-oriented programming language developed by Microsoft in 2000 that runs on the .NET Framework. Whether you’re creating Windows applications, diving into Unity game development, or working on enterprise solutions, C# is one of the top choices for developers worldwide. The C# specification details a minimum set of types and class libraries that the compiler expects to have available.
Versions
C# code is compiled into intermediate language (IL) code, which is then executed by the CLR. The use of Just-In-Time (JIT) compilation allows C# programs to run efficiently, and optimizations in recent versions of the .NET framework have improved performance. Its syntax is clean, and many complex features found in other languages, such as pointers, are either minimized or avoided altogether. Boxing is the operation of converting a value-type object into a value of a corresponding reference type.108 Boxing in C# is implicit. Most of the time people call this a “try-catch” code block, because of the “try” and “catch” functions being used and accessible on all C# versions.
Distinguishing features
Instances of value types neither have referential identity nor referential comparison semantics. Equality and inequality comparisons for value types compare the actual data values within the instances, unless the corresponding operators are overloaded. Value types are derived from System.ValueType, always have a default value, and can always be created and copied. Other examples are enum (enumerations) and struct (user defined structures).
This was a design decision by the language’s lead architect to avoid complications and to simplify architectural requirements throughout CLI. You will learn C# programming for desktop applications in a way that will get you up and running in no time. You will be equipped to become an employable .NET developer in any organization. We will grow your knowledge step by step throughout the course, and we will challenge you to be the best that you can be.
It is now a key language for building applications on Microsoft platforms such as Windows, Azure, and .NET Core. The only implicit conversions by default are those that are considered safe, such as widening of integers. This is enforced at compile-time, during JIT, and, in some cases, at runtime. No implicit conversions occur between Booleans and integers, nor between enumeration members and integers (except for literal 0, which can be implicitly converted to any enumerated type).
Since its introduction, C# has been widely adopted and is the de facto programming language for most Windows-based development. The language, along with the .NET framework, can also be used to develop applications for systems running Linux, macOS, iOS or Android, although C# is used primarily to develop Windows applications. c sharp programming language C# is a robust language that ensures high reliability and easy debugging. Features like exception handling, garbage collection, and type safety contribute to its reliability allows developers to write secure and error-free code. C# has evolved with many updates and new features and including support for dynamic programming, asynchronous programming, and LINQ (Language Integrated Query).
C# was developed by Anders Hejlsberg at Microsoft as part of the .NET initiative. The language was introduced as a part of the .NET Framework in 2000, aiming to provide a simple and modern language that would overcome the limitations of other languages like C++ and Visual Basic. C# was designed to be a safe, efficient, and easy-to-use language for building a wide range of applications. This C# tutorial covers everything from beginners to advanced level.
The newly released C# emphasized source code portability with support for both hosted and embedded systems. When building C# applications, developers can use type declarations to create new types. Type declarations are based on six of the subcategories available to value and reference types. They include struct types, enum types, tuple value types, class types, interface types and delegate types. The .NET framework also supports Language-Integrated Query (LINQ), a set of technologies that integrate query capabilities directly into the C# language. In addition to simplifying data access, LINQ offers developers a consistent experience when accessing data from objects, relational databases or Extensible Markup Language resources.
