  1. Capability to change from Best Performance to Best Appearence like in Windows

    Capability to select Best Appearence ot Best Performance, like it happens on Windows and WPF and Silverlight would take on the effects applied and the animations and so on that would be applied and disable them whenever possible, or even by having some kind of Attached Property stating the level of Performance in which that element would happen.

    This would allow those people that like things with more performance rather that being pretty to do so, without us providing several themes for each one.

    In the case of Effects I think it would be easy to identify what to de…

    • Make more WPF features work in partial trust

      It would be great if more WPF features were available in partial trust like bitmap effects applied to my application UI, access to more than just the domain of origin.

      • Multiple Code behind Partial Classes

        When creating partial classes for a XAML code behind class have the partial classes all reside under the XAML file in the solution explorer. Right now when you add a XAML file to a project 1 partial class (code behind) is nested in a node underneath the XAML file. If I add a new partial class for the code behind to hold event handlers it is in the solution explorer on its own. It would be nice if it would nest in a 2nd node underneath the XAML file.

        • Allow merged styles in controls, just like CSS

          Allow merged styles in controls, just like CSS. Inheritance of styles may not be what me want in some cases.

          • Make the controls MVVM friendly.

            ie Date and calendar controls are not too MVVM friendly when you need to set blackout days or events.

            • XAML - Move storyboards and visual states to a ".g" file

              One of XAML's key strengths is that its easily human readable and simple enough to be edited in Notepad. Unfortunately, the XAML generated by Blend is often verbose and greatly reduces the readability. I propose the verbose XAML which is rarely edited by hand, such as storyboards and visual states, be moved to a separate designer-only file in the same way layout code was stored in a ".g" file for WinForms. This would greatly improve my ability to digest and edit the pieces of XAML that I may commonly want to see in text rather than edit in a designer.

              • Make Stroke or Touch related event ignore Mouse event

                I use InkCanvas and it does not ignore Mouse event during touch or stroke related event. I have to kill mouse device by editing registry, what a hack! So, I'd like to ignore Mouse related event on stroke treatment.

                • Cross Platform

                  Make it cross platform, please!
                  Nobody would use another framework again. What are a few Windows licences compared to that? You could change the world!

                  • Nice and customisable controls with touch support

                    Everyone needs to show data to users in a nice way. I think WPF lacks enough basic controls with touch support, e.g.:
                    ScrollViewer with fancy finger scrolling and GPU acceleration
                    StackPanel with item drang&drop sorting
                    ScrollViewer with 3D scrolling and GPU acceleration
                    etc.

                    I think, Surface controls are pretty nice but we need more. SurfaceScrollViewer is the best in Surface controls but verry buggy (too many times I scroll down and the result is that I am still at the same position). Also we need to control scrolling animation length and scrolling velocity.

                    Simplified: We need fancy customisable controls smartphones-like.

                      • Fix DataGrid handling of INotifyDataErrorInfo

                        .NET 4.5 introduced INotifyDataErrorInfo in WPF. However, it doesn't behave correctly with DataGrids. The row indicator doesn't appear at the right time, nor does it clear when the error goes.

                        Here is the issue on Connect:

                          • Integrate native Aero Glass (DWM) controls into WPF as you did with JumpLists

                            When dealing with extending the glass into the client aerea you have to use native DWM calls and DPI calculations to get a proper effect.
                            How about a property or something to control aero glass behavior?

                            Like a property in the window that takes a Size object: ExtendGlass usage:
                            <Window ExtendGlass={Binding ElementName=NavigationBorder, Path=Width, Converter={StaticResource DoubleToLeftSizeConverter}}>

                            • Fix PrintDialog threadsafety + owner window

                              Right now, System.Windows.Controls.PrintDialog takes its owner window from the Application.Current.MainWindow property. This means only that one window can open it property, and only one thread can use it. This makes it pretty near useless; you have to substitute the windows-forms dialog instead to work around this.

                              • Make DataGridTemplateColumn properties support data binding

                                DataGridTemplateColumn currently does not support data binding of its properties. For example, if you want to set the Header of each column dynamically based on data, you can't. You have to hard code the data in the XAML file. Another example is Visibility. Given that AutoGenerateColumns doesn't work for complex data types, there's little that can be done in WPF to dynamically displace complex tabular data. There are some workarounds, such as Josh Smith's DataContextSpy, but they are all kludgy and painful. In general, properties in WPF controls and components should support data binding out of the box.

                                • provide better design time support for WPF

                                  I am a devoted user of WinForms' technology, I recently started to develop in WPF 4 and I noticed that my productivity is lowered into creating GUI even banal.
                                  The Visual Studio designer for WPF can not even remotely stand comparison with WinFroms one, so there are tons of XAML to write by hand.
                                  In the visual studio designer certainly less functional part is the PropertyGrid that can not be of help if not to set the boolean fields.
                                  I hope that the next version of VS there is a much better designer

                                        • Change binding before control is loaded

                                          Currently, it is not possible to change a binding or datacontext before a control is loaded. Therefore, you will have to wait until the control is loaded (and handle a lot of binding errors), and then replace the binding or datacontext value.
