Making WPF applications look Metro-styled, even in Windows 7? (Window Chrome / Theming / Theme)

What I did was creating my own Window and Style. Because I like to have control over everything and I didn't want some external libraries just to use a Window from it. I looked at already mentioned MahApps.Metro on GitHub

and also very nice Modern UI on GitHub. (.NET4.5 only)

There is one more it's Elysium but I really didn't try this one.

The style I did was really easy when I looked how it's done in these. Now I have my own Window and I can do whatever I want with xaml... for me it's the main reason why I did my own. And I made one more for you too :) I should probably say that I wouldn't be able to do it without exploring Modern UI it was great help. I tried to make it look like VS2012 Window. It looks like this.

Here is code (please note that it's targeting .NET4.5)

public class MyWindow : Window{    public MyWindow()    {        this.CommandBindings.Add(new CommandBinding(SystemCommands.CloseWindowCommand, this.OnCloseWindow));        this.CommandBindings.Add(new CommandBinding(SystemCommands.MaximizeWindowCommand, this.OnMaximizeWindow, this.OnCanResizeWindow));        this.CommandBindings.Add(new CommandBinding(SystemCommands.MinimizeWindowCommand, this.OnMinimizeWindow, this.OnCanMinimizeWindow));        this.CommandBindings.Add(new CommandBinding(SystemCommands.RestoreWindowCommand, this.OnRestoreWindow, this.OnCanResizeWindow));    }    private void OnCanResizeWindow(object sender, CanExecuteRoutedEventArgs e)    {        e.CanExecute = this.ResizeMode == ResizeMode.CanResize || this.ResizeMode == ResizeMode.CanResizeWithGrip;    }    private void OnCanMinimizeWindow(object sender, CanExecuteRoutedEventArgs e)    {        e.CanExecute = this.ResizeMode != ResizeMode.NoResize;    }    private void OnCloseWindow(object target, ExecutedRoutedEventArgs e)    {        SystemCommands.CloseWindow(this);    }    private void OnMaximizeWindow(object target, ExecutedRoutedEventArgs e)    {        SystemCommands.MaximizeWindow(this);    }    private void OnMinimizeWindow(object target, ExecutedRoutedEventArgs e)    {        SystemCommands.MinimizeWindow(this);    }    private void OnRestoreWindow(object target, ExecutedRoutedEventArgs e)    {        SystemCommands.RestoreWindow(this);    }}

The solution I ended up choosing was MahApps.Metro (github), which (after using it on two pieces of software now) I consider an excellent UI kit (credit to Oliver Vogel for the suggestion).

It skins the application with very little effort required, and has adaptations of the standard Windows 8 controls. It's very robust.

A version is available on Nuget:

You can install MahApps.Metro via Nuget using the GUI (right click on your project, Manage Nuget References, search for ‘MahApps.Metro’) or via the console:

PM> Install-Package MahApps.Metro

It's also free -- even for commercial use.

Update 10-29-2013:

I discovered that the Github version of MahApps.Metro is packed with controls and styles that aren't available in the current nuget version, including:

Datagrids:

Clean Window:

Flyouts:

Tiles:

The github repository is very active with quite a bit of user contributions. I recommend checking it out.

i would recommend Modern UI for WPF .

It has a very active maintainer it is awesome and free!

I'm currently porting some projects to MUI, first (and meanwhile second) impression is just wow!

To see MUI in action you could download XAML Spy which is based on MUI.

EDIT: Using Modern UI for WPF a few months and i'm loving it!
