Integrating TFS with Dynamics CRM CrmSvcUtil.exe for proxy generation in CI builds

Hello

    I want to know if someone has been done integration with TFS using CI Builds for regenerate the .cs classes that the tool CrmSvcUitil.exe (Dynamics sdk) provide.

     I have done something similar in the past with VS 2010 SDK, in Build Server calling "run custom tools" command for regenerate the edmx file structure before compile the solution.

    Any ideas?

regards,

Javier
