.net - Using WSS 3.0 console application on SharePoint 2013 -

we have console application used administer wss 3.0 sites. application uses microsoft.sharepoint assembly, in wss 3.0 of version 12.0.0.0

now, want use same console application on sharepoint 2013, without having rebuild new 1 specific version. since sharepoint 2013 comes version 15.0.0.0 of microsoft.sharepoint assembly, have created application configuration file following content:

<?xml version="1.0" encoding="utf-8" ?> <configuration>    <runtime>       <assemblybinding xmlns="urn:schemas-microsoft-com:asm.v1">        <dependentassembly>          <assemblyidentity name="microsoft.sharepoint"                            publickeytoken="71e9bce111e9429c"                            culture="neutral"      />          <!-- redirecting version 15.0.0.0 of assembly. -->          <bindingredirect oldversion="12.0.0.0"                           newversion="15.0.0.0" />        </dependentassembly>       </assemblybinding>    </runtime> </configuration> 

it doesn't work however, binding fails. ideas why?
