<h1>Native Query Optimization At Build Time</h1>
<p>If the platform you're running doesn't support optimization at runtime you can use the compile-time optimization. <a href="../../../../advanced_topics/enhancement_tools.htm" target="" title="" alt="" class="MCXref" xrefformat="See "{paratext}"">See "Enhancement Tools"</a></p>
<h2>Create the Enhancement Task</h2>
<p>First we define the enhancement-task. This task will process the <span class="PrimaryArtefact">assembly</span> and enhance it. </p>
<p MadCap:conditions="Primary..NET">You can add this to the existing project-files. The .csproj or .vbproj are actually MSBuild-files. Open them with a XML-Editor and add the needed parts.</p>
<div class="codesnippet" MadCap:conditions="Primary.c#">
<pre class="prettyprint" xml:space="preserve"><Target Name="AfterBuild">
<Db4oEnhancerMSBuildTask Assemblies="@(Db4oEnhance)" />
</Target></pre>
<div class="codesnippet-meta">simple-enhance-example.csproj: Define a target which runs the task
<div class="codedownload"><a href="../../../../CodeExamples/enhancement/buildtime/Example-enhancement-buildtime-csharp.zip" class="codedownload" MadCap:conditions="Primary.Online">Download Code</a></div><div class="codedownload copylink-marker" MadCap:conditions="Primary.Online"><a href="#copy">Copy Code</a></div></div>
</div>
<p>And the execute the task after the compilation.</p>
<div class="codesnippet" MadCap:conditions="Primary.c#">
<pre class="prettyprint" xml:space="preserve"><Target Name="AfterBuild">
<Db4oEnhancerMSBuildTask Assemblies="@(Db4oEnhance)" CommandLine="-nq" />
</Target></pre>
<div class="codesnippet-meta">simple-enhance-example.csproj: Only enhance native queries
<div class="codedownload"><a href="../../../../CodeExamples/enhancement/buildtime/Example-enhancement-buildtime-csharp.zip" class="codedownload" MadCap:conditions="Primary.Online">Download Code</a></div><div class="codedownload copylink-marker" MadCap:conditions="Primary.Online"><a href="#copy">Copy Code</a></div></div>
</div>
<p MadCap:conditions="Primary..NET">Now Visual Studio will automatically run the tasks for each build. You don't need to change anything else.</p>
<p>Often it's practical to have all persistent classes in a separate project or compile unit. Then the enhancement script runs only for this project. This makes it easy to enhance only the classes for the persistent objects.</p>
<p>There are lot of possibilities to tweak and configure the build-time enhancement so that it fits your requirements. <a target="" title="" alt="" MadCap:conditions="Primary..NET" class="MCXref" xrefformat="See "{paratext}""> See "Build Time Enhancement"</a></p>
