Lecture One - Introduction

The Microsoft .NET platform provides all of the tools and technologies that you need to build distributed Web applications. It exposes a language independent, consistent programming model across all tiers of an application while providing seamless interoperability with, and easy migration from, existing technologies. The .NET platform fully supports the Internet’s platform neutral, standards-based technologies, including HTTP, Extensible Markup Language (XML), and Simple Object Access Protocol (SOAP). C# is a new language specifically designed for building applications in the .NET environment. As a developer, you will find it useful to understand the rationale and features that provide the foundation for the .NET platform before you start writing C# code. The .NET Framework is based on a new Common Language Runtime. The Common Language Runtime provides a common set of services for projects built in Microsoft Visual Studio.NET, regardless of the language. These services provide key building blocks for applications of any type, across all application tiers. Microsoft Visual Basic ®, Microsoft Visual C++®, and other Microsoft programming languages have been enhanced to take advantage of these services. Third-party languages that are written for the .NET platform also have access to the same services
