What is the difference between C#.NET and VB.NET?

Ultimately, personal preference. Both use the same code base, and both compile into the same intermediate language. You can even use assemblies normally linked to the other language: I've written C# code that used methods found in Microsoft.VisualBasic.

In my experience, VB is slightly more versatile, in that it can do a few very arcane things that you cannot do in C#, like write reference extensions. By and large, though, the only difference between VB and C# is which language you are most comfortable using.

This topic came up in The Lounge a few days ago. Have a look at what lots of CPians thought[^].

Syntax.        

You should have done google for this.

Complete Comparison for VB.NET and C#[^]

None at all.

They are both ALGOL derived OOP .NET Developers tools, with a slightly different syntax and different functionalities.

They can both do more or less the same things, but, C# is what you should program in, and VB is often what you have to program in for the benefit of the management.

Elephants, because bananas don't have bones.

C# supports pointers to an extent. VB.NET doesn't support pointers.

Look here[^]

I think you should be reading a book or two.....
