Xml-Script Support

Try to take a look at this reading about XML Script - http://www.xmlscript.org/docs/Tutorial.Contents.html
xml-script has been moved to Preview component. You have to add reference toMicrosoft.Web.Preview.dll and add scriptmanager as followed:
<asp:ScriptManager ID="ScriptManager1" runat="server">
<Scripts>
<asp:ScriptReference Assembly="Microsoft.Web.Preview, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
Name="Microsoft.Web.Resources.ScriptLibrary.PreviewScript.js" />
<asp:ScriptReference Assembly="Microsoft.Web.Preview, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
Name="Microsoft.Web.Resources.ScriptLibrary.PreviewGlitz.js" />
<asp:ScriptReference Assembly="Microsoft.Web.Preview, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
Name="Microsoft.Web.Resources.ScriptLibrary.PreviewDragDrop.js" />
</Scripts>
</asp:ScriptManager>
