C# is a programming language of .Net Framework as well as an object oriented programming language developed by Microsoft. C# is designed for Common Language Infrastructure (CLI). It contains the executable code and runtime environment that makes the users able to use various high-level languages on different computer platforms and architectures. It is a Component oriented Structured language and Can be compiled on variety of computer platforms and produces efficient programs. C# is a easy, modern, general-purpose, object-oriented programming language developed by Microsoft within its dot.NET initiative. This course will help you to learn basic and Advance Concept of C#.

Course Objectives:

After completion of this course you will be able to:

• Understand and apply C# syntax and .NET framework in creating applications.
• Utilize various data types and expressions to manipulate data effectively.
• Master C# language constructs for structured programming and code organization.
• Implement methods, including overloading, for code modularity and reuse.
• Develop robust error handling within applications through exception management.
• Construct and manipulate collections, structs, enums, and handle events for complex data management.
• Design and implement classes, interfaces, and generics to create scalable and maintainable code.
• Apply inheritance and polymorphism to create class hierarchies that enhance code flexibility.
• Perform file I/O operations, serialization, and work with streams for data persistence.
• Access and manipulate databases using Entity Framework and LINQ for data-driven applications.
• Create responsive applications using multitasking, asynchronous calls, and resolve conflicts.
• Develop Graphical User Interfaces (GUIs) with data binding and styling for improved user experiences.
• Optimize application performance through performance tuning techniques.
• Employ C# interoperability features to manage resources and integrate with other systems or applications.
