We have a webservice named, let's say Foo.

So there is a Foo.svc file and a code behind Foo.svc.cs.

We add a silverlight project and wish to use the Foo.svc services so we add a Service Reference and call it's namespace FooBar.

This creates the following files :

* Reference.cs
* Reference.svcmap
* Foo.xsd
* Foo.disco
* configuration.svcinfo
* Foo.wsdl
* Also various \*.datasource files.

Over time we update the Foo.svc and add more Web Services (methods and interfaces) and the number of files in the FooBar directory is growing.

I have 26 Foo(nn).xsd files in this directory - where nn = 1 to 26. 

My configuration.svcinfo is upto configuration91.svcinfo.

My question is this? Do any of these files need to be version controlled? Can they all be deleted each time you do a build \ deploy (as long as you do an update service reference)?
