Optional query string parameters in URITemplate in WCF?

Question

I\'m developing some RESTful services in WCF 4.0. I\'ve got a method as below:

[OperationContract]
    [WebGet(UriTemplate = \"Test?format=XML&records={r

While this is an old question, we still come to this scenario from time to time in recent projects.

To send optional query parameters, I created WCF Web Extensions nuget package.

After installation, you can use the package like this:

using (var factory = new WebChannelFactory(new WebHttpBinding()))
{
    factory.Endpoint.Address = new EndpointAddress(ServiceUri);
    factory.Endpoint.EndpointBehaviors.Add(new QueryParametersServiceBehavior());
    using (var client = factory.CreateWebChannel())
    {
        client.AddQueryParameter("format", "xml");
        client.AddQueryParameter("version", "2");
        var result = client.Channel.GetReport();
    }
}

Server side you can retrieve the parameters using WebOperationContext:

WebOperationContext.Current.IncomingRequest.UriTemplateMatch.QueryParameters;
