.NET class library
.NET structure comes with just one category selection. And that all developers need to learn!! Whether they create the value in C# or VB.NET or J#, it doesn't matter; you just use the .NET category selection. There is no class's particular to any terminology. There is nothing more you can do in a terminology, which you can't do in any other .NET terminology. You can create value in C# or VB.NET with the same variety of wrinkles of value, same efficiency and same efficiency, because everyone uses same .NET category selection.
