How can I "clear" the vendor defined <controls> in my child app's web.config?
Parent Web Config.
<system.web>
<pages>
<controls>
<!-- START: Vendor Custom Control -->
<add tagPrefix="asp" namespace="VENDOR.Web.UI.Base" assembly="System.Web.Extensions, Version=1.0.61025.0, Culture=neutral />
...
<!-- END: Vendor Custom Control -->
...
</controls>
<tagMapping>
<add tagType="System.Web.UI.WebControls.WebParts.WebPartManager" mappedTagType="Microsoft.Web.Preview.UI.Controls.WebParts.WebPartManager" />
<add tagType="System.Web.UI.WebControls.WebParts.WebPartZone" mappedTagType="Microsoft.Web.Preview.UI.Controls.WebParts.WebPartZone" />
</tagMapping>
</pages>
</system.web>
Child:
<system.web>
<pages>
<controls>
<add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
<add tagPrefix="asp" namespace="System.Web.UI.WebControls" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
</controls>
<tagMapping>
<clear/>
</tagMapping>
</pages>
</system.web>
I have it working for the <tagMapping> section, but <controls> does not support <clear/> (or ).
