DevExpress, which creates add-on components and tools for Windows and Delphi, has posted its 2011 roadmap. This shows more convergence between components for Silverlight and WPF:

In essence, by the end of the year, the functionality of DXGrid, DXEditors, DXDocking, and DXRibbon will be the same across both platforms.

As for Windows Forms, or winforms, the roadmap says:

With regard to the Windows Forms controls, it is most likely that there will be a large number of smaller enhancements and new features rather than any large complex new control. The reason for this is simple: we believe that our offerings for this platform are very mature and robust.

Customers posting comments to CTO Julian Bucknall’s blog are not happy:

It is sad to see Winforms pushed back so much. WPF is still too slow on most computers for major apps and SL is not mature enough for a complete ERP app.

says Sigurd Decroos, while Heiko Mueller is more blunt:

Sorry guys, but with this roadmap I will not extend my subscription. I use only WinForms and ASP.NET and I’m not interested in WPF/Silverlight – WPF at this time for me is not suitable for my kind of applications (larger business Apps). Silverlight in my eyes is a dead technology – HTML5 is the future for rich internet applications.

Porting is also an issue says Ioannis Mpourkelis:

I believe that you should put more resources on the WinForms controls for 2011. Winforms is here to stay for many years, especially for the companies who want to support existing Winfroms applications. Currently it is impossible to port WinForms applicaitons to Silverlight and very difficult to port WinForms applications to WPF.
