What is C#.NET?

C#.NET is one of the Microsoft programming languages. It is the most powerful programming language among all programming languages available in the .NET Framework. The C#.NET contains all the features of C++, VB.NET, and JAVA, and also some additional features. The C#.NET programming language is designed to be simple, modern, general-purpose, and object-oriented.

C# is just a simple, secure, robust, portable, platform-independent, architectural neutral, multithreaded, object-oriented programming language with a strong type exception handling mechanism for developing different kinds of applications such as Web, Windows Form, Console, Web Services, Mobile Apps, etc.

C# is pronounced as C-Sharp. It is an object-oriented programming language provided by Microsoft that runs on the .NET Framework. C# is a modern, general-purpose, object-oriented programming language developed by Microsoft and approved by the European Computer Manufacturers Association (ECMA) and the International Standards Organization (ISO).

C# is approved as a standard by ECMA and ISO. C# is designed for CLI (Common Language Infrastructure). CLI is a specification that describes executable code and runtime environment. C++, Java, Eiffel, Modula-3, Pascal, etc influence the C# programming language. Languages.

Types of Applications Developed using C#:

With the help of the C# programming language, we can develop different types of secured and robust applications:

  1. Window Applications
  2. Web Applications
  3. Distributed Applications
  4. Web Service Applications
  5. Database Applications
  6. Mobile Applications, Etc.
Features of C#

Although C# constructs closely follow traditional high-level languages, C and C++ are object-oriented programming languages. It has a strong resemblance with Java; it has numerous strong programming features that endear to many programmers worldwide. Following is the list of a few important features of C# −

  1. Simple: C# is a simple language in the sense that it provides a structured approach (to break the problem into parts), a rich set of library functions, data types, etc.
  2. Modern Programming Language: C# programming is based on the current trend, and it is very powerful and simple for building scalable, interoperable, and robust applications.
  3. Object-Oriented: C# is an object-oriented programming language. OOPs, make development and maintenance easier, whereas in Procedure-oriented programming language, it is difficult to manage if code grows as the project size grows.
  4. Type-Safe: C# type safe code can only access the memory location it has permission to execute. Therefore, it improves the security of the program.
  5. Interoperability: The interoperability process enables the C# programs to do almost anything a native C++ application can do.
  6. Scalable and Updateable: C# is an automatic scalable and updateable programming language. We delete and update the old files with new ones to update our application.
  7. Component Oriented: C# is a component-oriented programming language. It is the predominant software development methodology used to develop more robust and highly scalable applications.
  8. Structured Programming Language: C# is a structured programming language in that we can break the program into parts using functions. So it is easy to understand and modify.
  9. Rich Library: C# provides many inbuilt functions that make development fast.
  10. Fast Speed: The compilation and execution time of the C# language is fast.

Prerequisites to Learn C#.NET

Learning C# and the .NET framework requires some foundational knowledge and skills. Here’s a list of prerequisites that will help you as you start your journey with C# and .NET:

  • Basic Programming Concepts: You should understand basic programming concepts such as variables, data types, control structures (if-else statements, loops), functions/methods, and error handling.
  • Object-Oriented Programming (OOP): C# is an object-oriented language, so knowledge of OOP principles (encapsulation, inheritance, polymorphism, and abstraction) is important.
  • IDE (Integrated Development Environment): Familiarize yourself with an IDE such as Visual Studio, which is the most commonly used for C# development. Understanding how to use an IDE will greatly enhance your productivity.
  • Understanding of .NET Framework/.NET Core/.NET 5+: While you can learn about .NET as you go, having a basic understanding of the .NET runtime, its class libraries, and the differences between the .NET Framework, .NET Core, and .NET 5+ will be very useful.
  • Syntax of Another Programming Language: If you’re already familiar with another C-like programming language (Java, C++, JavaScript), learning C# will be easier, as you’ll recognize many syntactic conventions.
  • CLI (Command Line Interface): Basic knowledge of command line usage can be beneficial, especially if you work with .NET Core or later versions, which offer a powerful CLI.
  • Basic Understanding of Software Development Concepts: Knowing what source code is, what a compiler does, and how an application runs on a computer will be fundamental.
  • Version Control Systems: Familiarity with a version control system, such as Git, is not strictly necessary but is extremely beneficial for managing your code as you learn.
  • Problem-Solving Skills: Programming effectively is about solving problems and creating solutions. Strengthening your problem-solving skills will be a significant advantage.
  • Databases: A basic understanding of databases and SQL is beneficial, especially if you aim to build data-driven applications.
  • HTML/CSS (For Web Development): If you’re interested in web development with ASP.NET, a basic understanding of HTML and CSS is necessary.
  • JavaScript (For Web Development): For full-stack web development with C# on the server side, knowledge of JavaScript and familiarity with front-end frameworks can be very useful.
  • Understanding of REST and HTTP: If you are looking into web development or creating web services with C#, knowing REST principles and how HTTP works is beneficial.
  • XML/JSON: An understanding of data formats like XML and JSON is important for web services and many types of C# applications.
  • Unit Testing: Knowledge of unit testing concepts and frameworks like NUnit or MSTest will be important for writing testable code.

Starting with these basics, you’ll be able to tackle C# and the .NET framework more effectively. It is good to have .NET Framework and Visual Studio installed on your computer, as it might assist you in executing the examples yourself and learning how it works.

Important Points:

C#: C# (pronounced “C Sharp”) is a modern, object-oriented, and type-safe programming language developed by Microsoft. Anders Hejlsberg and his team created it, first released in 2000. The language is syntactically similar to Java and is easy for users familiar with C, C++, or Java to learn. C# is designed to be used for developing a wide range of applications that run on the .NET Framework or, more recently, on .NET Core and .NET 5+.

.NET Framework: The .NET Framework is a software development framework—also developed by Microsoft—that provides a controlled programming environment where software can be developed, installed, and executed on mainly Windows-based operating systems. It includes a large class library named Framework Class Library (FCL) and provides language interoperability across several programming languages. Programs written for .NET Framework execute in a software environment named the Common Language Runtime (CLR), an application virtual machine that provides services such as security, memory management, and exception handling.

.NET Core and .NET 5+: .NET Core is the cross-platform, open-source successor to the .NET Framework. It’s designed to run on multiple operating systems, such as Windows, Linux, and macOS. Starting with .NET 5, the platform aims to unify the .NET Framework and .NET Core into a single framework that can be used for all types of .NET development.

When someone refers to “C#.NET,” they are typically talking about the C# language in the context of writing applications that run on the .NET platform, whether that’s the original .NET Framework or the newer, cross-platform .NET Core/.NET 5+.

    First I would like to thank Dotnet for sharing these materials. These are really good and up-to the point and very understandable. Anyone with basic knowledge can also read these and increase their knowledge.

  2. Can you add asp concepts too like all webform concepts including lambda expression and linq concepts?…It would be more greatful

  3. Content of every topics is so useful .I want to request u to pls share the contents of ADO.net and ASP.net also..

  4. The concepts are useful for performance tuning aspects also. Auto mapper very powerful to design domain driven related stuff.
    If we are familiar with Lambda, complex collections (how to retrieve from complex type collection) with combination of Automapper, then we can easily implement any kind of logic w.r.t layering systems.
    Here my question is: Automappers are internally defined from reflection logic(gettype comparison b/w classes and their properties?)…
    Please continue your research on Architectural patterns and their evaluations start to till date (please explain successful patterns).

    Happy coding
