In recent thread on IB board, Kent commented that C++ was the way to
go for creating serious apps. Is this really true any more if you're
starting from .NET, where all of its languages are based on same
underlying runtime lib.s and architecture. For purposes of building a
killer trading app, does it really matter much whether you're using
VB.NET or C#.NET or C++? And can't you just mix in legacy C and C++
lib.s as necessary?
