I know that since "native" delphi and delphi.net are different technologies it is unlikely to produce a tool that can migrate your old dfm forms to win forms for delphi prism. However is there a tool that facilitate such migration? Basically I have a "native" delphi project that I want to migrate to delphi .net, it is a desktop application, how do I go about that?
VCL and Winforms are enough different to make such conversion not easy. There are also some components that are Delphi specific without a direct .NET counterpart, and a conversion tool probably would fail if unsupported third party controls are used. The old VCL.NET framework was an attempt to make that transition easier, but failed. A conversion tool may be written, but IMHO it would be of limited use and work for simple forms only. There's no one I am aware of, and because most developers that migrated from Delphi to .NET went the VS/C# way - I see very little advantages of moving a desktop application from Delphi to Prism - there are very little reasons to write one.
The only tool wich i know to port Delphi Win32 and Delphi .Net Code to Delphi-Prism is Oxidizer, but this app does not translate the Delphi forms to Winforms, Oxydizer is good for converting library code and other non-visual related code, however it is still a great option to help you to translate your Delphi code.
