I've found a basic workaround: I've mapped the CuteSoft_Client folder as a virtual folder instead of copying it into the application root. This excludes it from the VS2005 build.

Note that this workaround doesn't work if in VS2005 you open the website from IIS (becouse it gets the virtual folder information too), while it works fine if you open it from filesystem.

 
Hope this can help your job.
