How to remove border when WindowStyle="None" AllowsTransparency=“False” and ResizeMode="CanResize"

Question

I have a window with the following properties

WindowState="Maximized"
WindowStyle="None, 
AllowsTransparency="False"
ResizeMode="CanResize"

But the problem is a border appears around the window. How can I fix it without changing any of these properties

When I set AllowsTransparency True some user controls such as PdfViewer,WebBrowser not displaying contents.

 <Window x:Class="WpfApplication8.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        WindowStyle="None"
        WindowState="Maximized"
        AllowsTransparency="False"
        ResizeMode="CanResize"
        UseLayoutRounding="True"
        Title="MainWindow">
    <Grid Background="Red"></Grid>
</Window>

Answer 1

You could use a WindowChrome:

<Window x:Class="WpfApplication8.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        WindowStyle="None"
        AllowsTransparency="False"
        ResizeMode="CanResize"
        UseLayoutRounding="True"
        Title="MainWindow">
    <WindowChrome.WindowChrome>
        <WindowChrome CaptionHeight="0" ResizeBorderThickness="5" />
    </WindowChrome.WindowChrome>
    <Grid Background="Red"></Grid>
</Window>
