I have a feature which specifies a custom user control to be added to the AdditionalPageHead delegate control as such:

<?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
    <Control Id="AdditionalPageHead"
        ControlSrc="~/_CONTROLTEMPLATES/15/CustomUserControl.ascx" /> 

The custom user control itself just adds a script block to the page.

When this feature is activated, MDS is disabled on the site collection.

I have set [assembly: MdsCompliant(true)] in the AssemblyInfo.cs and also added the attribute to the control.

public partial class CustomUserControl : UserControl
    protected void Page_Load(object sender, EventArgs e)

It looks like I may need to set SPContext.Current.Web.EnableMinimalDownload but I'm not sure where that needs to be done.

What else do I need to do to make sure activating this feature won't disable MDS?

    Are you overriding the render method? This is the only time I have seen this pattern disable MDS on the page load.

I've written a blog post on a few gotcha's when working with MDS


My guess is that your user control will need a code behind on it and use the SPPageContentManager to register your script in addition to the mdscompliant(true) attribute.
