WPF MessageBox window style

Question

How to apply the default Windows style to the standard MessageBox in WPF?

For example, when I execute next code:

MessageBox.Show("Hello Stack Overflow!", "Test", MessageBoxButton.OKCancel,      MessageBoxImage.Exclamation); 

I'm getting message box:

But in WinForms everything is OK with style:

MessageBox.Show("Hello Stack Overflow!", "Test", MessageBoxButtons.OKCancel,      MessageBoxIcon.Exclamation);

According to this page, WPF picks up the old styles for some of the controls.

To get rid of it, you have to create a custom app.manifest file (Add -> New item -> Application Manifest File) and paste the following code in it (right after the /trustInfo - Tag ):

<!-- Activate Windows Common Controls v6 usage (XP and Vista): --> <dependency>   <dependentAssembly>     <assemblyIdentity       type="win32"       name="Microsoft.Windows.Common-Controls"       version="6.0.0.0"       processorArchitecture="*"       publicKeyToken="6595b64144ccf1df"       language="*"/>   </dependentAssembly> </dependency> 

Then you have to compile your solution with this app.manifest (set it in the project properties -> Application -> Point to the new manifest in "Icons and manifest").

If you start your application now it should look like the WinForms- MessageBox.
