Before bark on .NET you should study the history:

The huge part of Borland always was with Anders Hejlsberg. I would say that Anders Hejlsberg + Philip Kahn = Borland. Now, when both of them are gone, Borland is just a name.

Borland lost its track long time ago, when they renamed it to Inprise. And Anders is still making IDE and programming language for developers. It called Visual Studio and C#.
