The ability to blend the different .net languages in a the same sourcecode, through the use of a new # tag.

Just like has XML Literals.


Public Module Module1

 Sub Main()
Dim n1 As Double=2
Dim n2 As Double=3
Dim result = Addition(n1,n2)
 End Sub
 public  double Addition(double x, double y) {
 return x + y;

The c# is probably wrong (not my best) but you get the gist.

Developers coding in prefered language.


I don't think it be that hard to implement, all the required mechnisms are already built; the compilers. It may need a new linker.


Blending languages would be nice, although I'd be happy with files being in one language but projects being in multiple. So if I find a neat class on the web that's in C# but I want to use it in my VB project, and I don't want two DLLs, I don't need to translate the C# to VB (and inevitably introduce errors).
