Error 409 WebServiceBindingAttribute is required on proxy classes. after creating a new build

After creating new build type 32bitDebug (based on Debug) according to How to: Create and Edit Configurations 

 

I received the following error during compile

Error     409     WebServiceBindingAttribute is required on proxy classes.     C:TFSmyProjectSGEN     MyAssemblyName

The instructions from SO answer http://stackoverflow.com/questions/354503/webservicebindingattribute-is-required-on-proxy-classes

In the properties for the project. In the Build Tab. Select “Generate Serialization assembly:” to Off

fixed the problem.
