This Microsoft Visual Studio 2015 Training Course emphasizes the C# language. It is current to Visual Studio 2015. Important newer features such as dynamic data type, named and optional arguments, the use of variance in generic interfaces, and asynchronous programming keywords are covered in a final chapter. A supplement covers the fundamentals of Language Integrated Query (LINQ). This Microsoft Visual Studio 2015 Training Course is intended to be fully accessible to programmers who do not already have a strong background in object-oriented programming in C-like languages, such as C++ or Java. It is ideal, for example, for Visual Basic 6 or COBOL programmers who desire to learn C#. A case study is used to illustrate creating a complete system using C# and .NET. Besides supporting traditional object-oriented features, such as classes, inheritance, and polymorphism, C# introduces several additional features, such as properties, indexers, delegates, events, and interfaces that make C# a compelling language for developing object-oriented and component-based systems. This Microsoft Visual Studio 2015 Training Course provides thorough coverage of all these features.
