The ScriptServiceAttribute applies to calling asmx web services via JavaScript. UriTemplates apply to WCF services. They don't intermix well. A bit more information... If you are planning on calling WCF services from JavaScript, you have a couple of choices. The easiest is to use what I refer to as the 'AJAX-Friendly' endpoint behavior: enableWebScript. I am assuming you have seen these, but I outlined this functionality in part II and part III of this series: http://www.robbagby.com/rest/rest-in-wcf-part-ii-ajax-friendly-services-creating-the-service/ and http://www.robbagby.com/rest/rest-in-wcf-part-iii-ajax-friendly-services-consuming-the-service/. This endpoint behavior will automatically generate a JavaScript proxy for you. In doing that, it precludes you from using PUT / DELETE, etc. Essentially, it only supports GET and POST. Further, it does not support UriTemplates. Hope that helps! Rob Hi Bryce,

I have a quick question with regard to UriTemplates, PUT's||POST's, and a RequestFormat of json: my application keeps throwing the error: "Only Web services with a [ScriptService] attribute on the class definition can be called from script.". In looking at the RestHandler under System.Web.Script.Services the IsRestMethod will always return true if the contenttype is set to json: internal static bool IsRestMethodCall(HttpRequest request) { if (string.IsNullOrEmpty(request.PathInfo)) { return false; } if (!request.ContentType.StartsWith("application/json;", StringComparison.OrdinalIgnoreCase)) { return string.Equals(request.ContentType, "application/json", StringComparison.OrdinalIgnoreCase); } return true; } Since you can't use the [ScriptService] attribute with uritemplates - I'm assuming I'm missing something totally obvious. Any pointers? thanks, Bryce Hey Rob,
Thanks for the great information on REST and WCF. I have a quick question with regard to UriTemplates, PUT’s||POST’s, and a RequestFormat of json: my application keeps throwing the error: “Only Web services with a [ScriptService] attribute on the class definition can be called from script.”.

In looking at the RestHandler under System.Web.Script.Services the IsRestMethod will always return true if the contenttype is set to json:
internal static bool IsRestMethodCall(HttpRequest request)
{
if (string.IsNullOrEmpty(request.PathInfo))
{
return false;
}
if (!request.ContentType.StartsWith(”application/json;”, StringComparison.OrdinalIgnoreCase))
{
return string.Equals(request.ContentType, “application/json”, StringComparison.OrdinalIgnoreCase);
}
return true;
}

Since you can’t use the [ScriptService] attribute with uritemplates – I’m assuming I’m missing something totally obvious. Any pointers?

thanks,
Bryce
