You could remove the JSON formatter if you don't intend to serve JSON:
var formatters = GlobalConfiguration.Configuration.Formatters;
formatters.Remove(formatters.JsonFormatter);
You also have the possibility to explicitly specify the formatter to be used in your action:
public object Get()
{
var model = new
{
Foo = "bar"
};
return Request.CreateResponse(HttpStatusCode.OK, model, Configuration.Formatters.XmlFormatter);
}

Changing the formatters collection is probably the best way, but I would be tempted to clear the collection and add back an XmlFormatter.
You could also force the accept header on all requests to be application/xml by using a MessageHandler
public class ForceXmlHandler : DelegatingHandler
{
protected override Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, System.Threading.CancellationToken cancellationToken)
{
request.Headers.Accept.Clear();
request.Headers.Accept.Add(new MediaTypeWithQualityHeaderValue("application/xml"));
return base.SendAsync(request, cancellationToken);
}
}
Just add this message handler to the configuration object.
config.MessageHandlers.Add(new ForceXmlHandler());

You can remove JSON formatter them in Application_Start
Use
GlobalConfiguration.Configuration.Formatters.Remove(GlobalConfiguration.Configuration.Formatters.JsonFormatter);
