Introduction to C# and .NET

Course:  CSHNI
Duration:  5 Days
Level:  I
Course Summary

This course provides an intensive architectural overview of the Microsoft .NET Development environment and the Common Language Runtime (CLR) using C# as the language of choice. It focuses on understanding how to develop applications and reusable classes that take advantage of the features exposed through the CLR. Specifically it will introduce you to the object model of .NET and more generally to the .NET Framework including ADO.NET, and Windows Forms Programming. We can use either Visual Studio .NET 2008, or Visual Studio 2010.

Who Should Take This Course

The primary audience for this course is the Professional Developer who is trying to learn the Microsoft .NET programming environment. Secondary Audiences would include Testing, Support, and Help desk personnel who need a broad understanding of these technologies. Additional Audiences might include the Management of teams of such individuals.

Recommended Prerequisites

Attendees of this course should have familiarity with basic programming constructs and knowledge of a programming language such as COBOL, FORTRAN, Assembler, C, C++, Java, BASIC or similar work experience.

Attendees will have the best experience when all attendees are at a similar experience level and have a similar programming background. When a class is composed of differing levels of expertise, remedial instruction may be required both in class and in additional sessions before or after the regular sessions.
