NDOC Error building documentation.

Using .NET Framework 3.5, I have nant -0.91-alpha2 which has support for framework 3.5 but I am getting t开发者_如何学Che following error when I try to build the documentation.

Error building Documentation.
       Object reference not set to an instance of object.
               Object reference not set to an instance of object

The documentation is to be generated by the following:

<target name="Documentation"> 
  <property name="nant.settings.currentframework" value="net-3.5"/> 
  <ndoc> 
    <assemblies> 
      <include name="Release\Project.dll" /> 
    </assemblies> 
    <summaries> 
      <include name="Release\Project.XML" /> 
    </summaries>
    <documenters> 
      <documenter name="MSDN"> //MSDN properties 
      </documenter> 
    </documenters> 
  </ndoc> 
</target>

NDoc does not support .NET 3.5

Look at SandCastle
