This issue can be fixed by adding an application manifest (Add -> New Item -> Application Manifest File)

    ...
</trustInfo>
<dependency>
    <dependentAssembly>
        <assemblyIdentity
            type="win32"
            name="Microsoft.Windows.Common-Controls"
            version="6.0.0.0"
            processorArchitecture="*"
            publicKeyToken="6595b64144ccf1df"
            language="*" />
    </dependentAssembly>
</dependency>

Under "Project Properties", point "Manifest" to the file you just created. This is optional for that the manifest can also just be deployed along with the EXE file.

Note: This manifest can be used for any executable, not only WPF, that needs to be "styled".
