Visual Basic .NET was released by Microsoft in 2002 as a successor to the original Visual Basic computer programming language. It was implemented on the .NET_Framework_1.0. The main new feature was managed code. Programmers familiar only with Visual Basic would probably have encountered difficulties working with the new version or adapting existing programs for it. == Obvious major differences == The new platform bore little resemblance to its predecessor. While development houses expected to be able to recompile their Visual Basic source to a .NET target, the reality of the situation was that Visual Basic.NET was a vastly different paradigm. Obvious syntax differences aside, Visual Basic.NET provides much the same functionality as C# (since they both compile down to MSIL, with the most obvious difference being the case insensitivity of Visual Basic.NET, maintaining the original case-insensitivity of Visual Basic), which is more of a problem for C# programmers trying to inter-operate with Visual Basic.NET developers than anything else. The basic syntax remains very similar: conditions, loops, procedures, sub-routines are declared and written in the same manner (see Visual Basic). Mobility from prior Visual Basic iterations to Visual Basic.NET really are ports of existing code: programmers with experience in both worlds are required to effectively target the new platform with older logic. The Visual Basic.NET developer will have to learn the use of the basic .NET types rather than what they have been used to in Visual Basic. A programmer who has only worked with Visual Basic may encounter a steep learning curve to migrate to Visual Basic.NET. A programmer who is versed in another language or who has had exposure to the .NET runtime should be able to cope. It would be better to think of Visual Basic.NET as an interface to .NET rather than a continuation of Visual Basic 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Comparison of Visual Basic and Visual Basic .NET」の詳細全文を読む スポンサード リンク
