This is the first tutorial as part of the Visual Basic .NET 2005 Training. In this tutorials we will be learning about the basics of The .NET Framework Architecture, The .NET vision, Common Language Runtime (CLR), .NET Framework Class Library and Microsoft Intermediate Language (MSIL). It's very important to learn the basics before we actually start with the Programming. The .NET framework is a software technology that is directed towards connecting information, people, systems and devices seamlessly. The high level of software integration that has been attempted through use of XML web services enables the creation of small, discrete, building block types of applications. These applications are connected to other applications over the Internet.
