NAnt fails with "Invalid element <checksum>. Unknown task or datatype"

Question

I had to move from nant-0.86 to nant-0.92

This part of the code now fails with: Invalid element <checksum>. Unknown task or datatype.

<target name="make_one_cksum">
   <!--  <echo message="ECHO za md5 ${filename}" /> -->
   <checksum algorithm="MD5" fileext="MD5_nov">
      <fileset>
         <include name="${filename}"/>
      </fileset>
   </checksum>
</target>

Any suggestions to make this work again?

You will need to update your NAnt.Contrib.Task to 0.93.

Requirements Assembly: NAnt.Contrib.Tasks (0.93.5041.0)
