delphi prism was developed by remobjects software and distributed by embarcadero from 2008 to replace delphi.net. it is a combination of remobjects's mostly delphi-compatible .net compiler (without rtl or vcl), a version of the microsoft visual studio shell without c# or vb support, and some embarcadero technologies such as dbexpress. prism is cross-platform capable insofar as it supports the mono .net libraries.
