The goal of this course is to provide students with the knowledge and skills they need to develop C# applications for the Microsoft .NET Platform. The course focuses on C# program structure, language syntax, and implementation details.

C# was created to be the programming language best suited for writing enterprise applications for .NET. C# combines the high productivity of Microsoft Visual Basic® with the raw power of C++. It is a simple, object-oriented, and type-safe programming language that is based on the C and C++ family of languages.

This course is intended for experienced developers who already have programming experience in C, C++, Visual Basic, or Java. These developers will be likely to develop enterprise business solutions.

At the end of the course, students will be able to:

• List the major elements of the .NET Framework and explain how C# fits into the .NET Platform.
• Analyze the basic structure of a C# application and be able to document, debug, compile, and run a simple application.
• Create, name, and assign values to variables.
• Use common statements to implement flow control, looping, and exception handling.
• Create methods (functions and subroutines) that can return values and take parameters.
• Create, initialize, and use arrays.
• Explain the basic concepts and terminology of object-oriented programming.
• Use common objects and reference types.
• Create, initialize, and destroy objects in a C# application.
• Build new C# classes from existing classes.
• Create self-contained classes and frameworks in a C# application.
• Define operators, use delegates, and add event specifications.
• Implement properties and indexers.
• Use predefined and custom attributes.

Before attending this course, students must have:

• Experience with programming in C, C++, Visual Basic, Java, or another programming language.
• Familiarity with the Microsoft .NET strategy as described on the Microsoft .NET Web site:
  • http://www.microsoft.com/net/.
• Familiarity with the .NET Framework as described on the MSDN® Magazine Web site:
  • http://msdn.microsoft.com/msdnmag/issues/0900/Framework/Framework.asp
  • http://msdn.microsoft.com/msdnmag/issues/1000/Framework2/Framework2.asp

• There are no Microsoft Certified Professional exams associated with this course.
