[CONTENTS] >>[Lesson 2]

Microsoft launched Visual Basic 2012  in the year  2012.   It is a fully object-oriented programming language implemented on the .NET Framework. Similar to the earlier version of VB.NET programming languages,  VB2012 is integrated with other Microsoft Programming languages in an IDE called Visual Studio Express 2012.

Although Microsoft had launched a few newer versions of Visual Studio until the latest Visual Studio 2017,  you can still download the older version Visual Studio 2012 Express Edition from the following link:

From the download link as shown in Figure 1.1, select the free Visual Studio Express 2012 for Windows Desktop.
