I suggest you ...

You've used all your votes and won't be able to post a new idea, but you can still search and comment on existing ideas.

  1. VideoRendererElement for integration of DirectShow and Media Foundation

    The VideoRendererElement could provide a renderer filter (DirectShow) or a media sink (MF) or an activation object (IMFActivate). You could use that in your DirectShow filter graph or MF topology.
    At the moment, the possibilities for using DirectShow/MF in a WPF application are dissatisfying: you can use a native window for video rendering (with all the airspace issues), you can use the combination of an EVR custom presenter and a D3DImage (it is awkward and uses the UI thread for updating the video image), and of course you can use MediaElement with all its limitations (video playback only).

    • XAML Based Shaders

      While WPF now supports effects, the method of creating them and integrating them into the app is a bit of a pain. It would be better if you could create HLSL directly in XAML. Plus, could we have support for triggers and binding in shaders?

      • Make TemplateBinding work in a multibinding

        TemplateBinding doesn't inherit from BindingBase which means you can't use it in a MultiBinding.

          • iOS and OSX support

            We're fighting a loosing battle when trying to port applications to iOS and OSX. How about helping some ppl out there that are already trying to allow cross platform support (Xamarin?). Even if it's just silverlight. I'm not sure if this is just a restriction from Apple's side... but it makes it very difficult to build consumer based applications in WPF when many of our customers are running apple products. Telling them to install windows as a virtual machine also doesn't make things that much easier (and cannot be done on iOS).

            • Add designer attribute in Xaml for DataContext type

              It'd be nice to be able to specify an x:Type for the designer to use when dealing with a DataContext, for use with DataTemplates and ViewModel-first MVVM. This would potentially allow intellisense to work when using VM-first style MVVM development.

                • Better custom chrome support for Window

                  It's without a doubt that custom chrome apps are becoming popular, with office as being a leader, and other MS apps.

                  It would be great if full support was baked into the window, I am speaking in terms of:

                  - Better drop shadow support for borderless windows
                  - Retaining animation for minimizing, maximizing windows
                  - Aero snap support
                  - Fixing issues when WindowStyle is none and maximizing causing it to be in Kiosk mode.
                  - Inherent and native support for extending glass into non client area.

                  There are far too much hacking, pinvoking to be done just to achieve these…

                  • Lazy initialization of dependency properties

                    Currently there's no easy way to initialize a dependency property lazily. This is a real issue for collection DPs, because they have to be explicitly created in XAML. I want to be able to specify a "InitCallback" delegate in the property metadata

                    • Validation with DataAnnotations like in ASP.NET MVC.

                      Also make Entity-Framework fully compatible and integrated with DataAnnotations validation.

                      • Native support for video capture and video streaming.

                        It would be nice to have the ability to support a Video capture device natively. Currently you have to jump through a lot of hoops to get this running via DirectShow interop or MediaPlayer ActiveX. I'm thinking of applications like Media players, PVR/DVR functionality, broadcast, etc that can be manipulated in WPF 3D and transforms.

                        • Add IsolatedStorageSettings (System.IO.IsolatedStorage.IsolatedStorageSettings) to WPF

                          In Silverlight you have the wonderful IsolatedStorageSettings class that allows you to save any kind of object (including sub-objects) in isolated storage.

                          For instance: IsolatedStorageSettings.ApplicationSettings["LastRun"] = DateTime.Now;

                          Please add that to WPF as well; maybe also with different visibilites like "Application", "User", "Machine".

                                    Currently you cannot databind to a read only DependencyProperty. How about changing this behavior to allow databinding to a read only DependencyProperty.

                                      • Make the WPF Ribbon look closer to the Windows Ribbon

                                        The current WPF ribbon is not too realistic... The application button is not the right color, nor is the ribbon tab the right gradient. There are some necessary animations not done, while there are animations not found in the Windows Ribbon. The buttons in the ribbon control group do not look similar to the Windows Ribbon buttons at all. I suggest that the WPF Ribbon be made more realistic before any additional development is done.

                                        • fix combobox dropdown z-index when using a shaped window

                                          Right now, when you use a "shaped window" set window transperancy to true, windows style to none, etc... And you place a combobox on the page, and run it. When you select the combo-box, the drop down select box appears BEHIND the window. this needs to be fixed
