Luckily there is a solution to this problem. Mono implementation of System.Core can be used to support optimized LINQ providers and expression interpreter contributed by <a href="http://www.mainsoft.com/">Mainsoft</a> to Mono's System.Core can be used to support full LINQ expression trees. </p> <p>These assemblies were used by db4o team to compile a new assembly, System.Linq.Expressions.dll, which provides LINQ support to .NET Compact Framework 3.5. In order to use the full LINQ functionality including optimization, add a reference to System.Linq.Expressions.dll in your project and enjoy. <![CDATA[ ]]></p> <script type="text/javascript" src="../../../SkinSupport/MadCapBodyEnd.js"> </script> </body> </html>
