C# is one of the most popular object oriented programming languages used for developing robust desktop, web services & applications. It is widely used in creating Microsoft applications at a larger scale.

For many years, C# is holding a good position in the list of top programming languages. It comes with a rich set of libraries making it a faster & efficient programming language used for game development along with development of windows application & server side applications.
Why is C# language so popular?

  1. Game Development: C# is used to create games using Unity game engine – a cross platform game engine to make real time 3D projects. In fact Unity is behind the virtual reality (VR) development of Oculus Rift VR games & Samsung Gear. This makes it a great choice for professionals who want to make a thriving career in the gaming or VR industry
  2. Easy to Learn: C# is an easy to read high-level language with many of the most complex tasks abstracted away, so the programmer doesn't have to worry about them. For example, memory management is removed from the user’s responsibility & handled by .NET’s garbage collection scheme
  3. Easy to Maintain: The C# programming code is checked for errors before it gets built into an app. Errors are easier to track. In general the codebase is consistent & easier to maintain as it grows in size & complexity
  4. Fast: C# is faster than dynamically typed languages because things are more clearly defined. So, when the app is running, the machine resources are not wasted on checking the code
  5. Object Oriented: C# supports major object-oriented programming features such as data encapsulation, inheritance, and polymorphism
  6. Interoperable: The code produced by C# can work easily with code produced by other languages made possible by using CLS – a set of rules that every language in the .Net framework has to follow
  7. Compatible: C# allows interoperation with other .Net language
  8. Supports Garbage Collection: It is a feature of .Net supported by C# that automatically reclaims memory occupied by unused objects
