How to mark obsolete classes/methods in the output with sandcastle

I'm开发者_开发问答 building an API documentation with Sandcastle. The code has multiple classes and methods which are marked deprecated. Now I want that in the API-documentation output these methods are clearly marked (crossed-out or other marker). However the Sandcastle output doesn't mark obsolete methods/classes at all.

My question is. What do I need to do to have the obsolete methods/classes marked by Sandcastle.

Thanks for any advice/help.

Well I found the issue. The issue is a mix of the API and Attribute filters I had in place.

So I added the System-namespace to my API filters, so that it includes the Obsolete-Attribute:

<apiFilter>
  <namespace name="System" expose="true">
    <type name="ObsoleteAttribute" expose="true" />
    <type name="SerializableAttribute" expose="false" />
  </namespace>
  <!-- rest of the stuff -->
</apiFilter>

And added it also to the list of Attribute-Filters:

<attributeFilter expose="true">
  <namespace name="System" expose="false">
    <type name="ObsoleteAttribute" expose="true" />
  </namespace>
  <!-- rest of the stuff -->
</attributeFilter>

I had the 'ObsoleteAttribute' in my attribute-filter, but not in the API-filter.
