ObjectivesThe 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.
Entry requirementsBefore 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.
