<h1><a name="kanchor15"></a>NQ Optimization On CF2.0</h1>
<p MadCap:conditions="Primary..NET">
<p>Due to some platform limitations, CompactFramework 2.0 users using the more
convenient delegate based Native Query syntax that want their queries to be
optimized are required to run the Db4oTool.exe command line utility on their
assemblies prior to deploying them. <a href="../../../../advanced_topics/enhancement_tools.htm" target="" title="" alt="" class="MCXref" xrefformat="See "{paratext}"">See "Enhancement Tools"</a></p>
<p>The utility, which can be found in
the /bin folder of .NET distribution, is required because the CompactFramework
API does not expose any of the delegate metadata needed by the Native Query
optimizer. The tool works by augmenting the bytecode with the necessary delegate
metadata and replacing ObjectContainer#Query invocations with
invocations to a lower level method that makes use of the additional
information.</p>
