C# is a versatile language used for a wide range of applications, including:
- Desktop Applications: Creating standalone applications for Windows, macOS, and Linux.
- Web Development: Building dynamic websites and web applications using frameworks like ASP.NET.
- Mobile App Development: Developing mobile apps for iOS and Android using Xamarin.
- Game Development: Creating video games using Unity and other game engines.
How to Open and Edit .cs Files?
You can open and edit .cs files using a variety of text editors and IDEs (Integrated Development Environments) that support C#. Popular options include:
