I'm not sure if it still does, but Delphi definitely used to support .NET.

Delphi.NET was a side project so to speak, and was mostly done under contract by RemObjects, which kept selling their compiler when Embarcadero decided to focus on native only.

Delphi.NET was so much central project that 8 only supported .NET. Nothing else was ever needed as it seemed. Delphi.NET was 8, 2005, 2006 and 2007, then dropped. It was hosted in common RAD IDE and language was close match.

Delphi Prism was bundled somewhere between 2009 and XE2, a 3rd party product, hosted in Visual Studio IDE and language was resembling, but not quite. Enough divergence to not make it possible sharing source text with native Delphi.

		(I work at RemObjects) - we've been working hard on reducing convergence recently, that is, still supporting our own Oxygene Pascal syntax but also accepting other variants of Pascal. We want it to be possible for someone to have a common source file as you suggest, much the same as you can with Delphi and FPC. It is possible today; we are working on the really esoteric syntax. Our 'Delphi Island' support also allows linking to BPLs. And we have our own IDE (for multiple platforms), as well as living inside VS.
