How To: Stop Visual Studio XAML Editor from Adding mc:Ignorable

Question

Whenever I run my Windows Phone application while the XAML page is open, Visual Studio adds the following to my XAML:

mc:Ignorable="d" 
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"   
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
d:DesignHeight="768" 
d:DesignWidth="480"

How can I stop it from doing so? I know it won't hurt me to keep it, but I don't want it in my code unless I need it.

Thanks

When creating any kind of predefined document Visual Studio uses built in default templates.

For instance for Visual Studio 2010 custom template for WPF UserControl looks:

<UserControl x:Class="$rootnamespace$.$safeitemname$"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
             mc:Ignorable="d"
             d:DesignHeight="300" d:DesignWidth="300">
    <Grid>

    </Grid>
</UserControl>

File location at my PC: C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\ItemTemplatesCache\CSharp\WPF\1033\WPFUserControl.zip\UserControl1.xaml

So as you can see Microsoft Team decided to include this namespace by default. I believe you can find such template for Windows Phone project as well, just look under the Visual Studio installation folder, and obviously you always can create and use own templates for any kind of document.

And what I found most neat - you do not need to restart Visual Studio in order to pickup template updates you made. I just removed mc:Ignorable from default demplate and tried to create a new UserControl - it was created using just updated template file, so Visual Studio 2010 pick up changes on the fly, this is nice, credits to Microsoft Team.

Looks like all available templates are grouped per Technology/Framework under this folder:

"C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\ItemTemplatesCache\CSharp\"
