Lets say I have this method in my WCF Service:
[WebGet(ResponseFormat= WebMessageFormat.Json,
UriTemplate = "users/{username}/bookmarks/{id}?format=json")]
[OperationContract]
Bookmark GetBookmarkAsJson(string username, string id)
{
HandleGetBookmark(username, id);
}
How is WCF wiring up the {username} to the username param? does it just do its magic and wire up and send the value for {username} to the string username and is it based on param to {username} match?
It matches the query string name with parameter name in operation. Both should match.

My first WEB servicee usinf Visual Studio 2013 Express WEB, and I can't make it restfull. basically want to return a json string and got the following service definition;
[OperationContract]
[WebInvoke(Method = "GET",
ResponseFormat = WebMessageFormat.Json, UriTemplate = "Name")]
string Name();
Implementation of Name just returns a string which is shown when I Invoke the function through the WCF Test Client, but calling the http://localhost:58116/Service1.svc/Name returns nothing. I was expecting a json representation of the Name.
Any idea's?
I have WCF webservice that has contract like this
[OperationContract]
void UpdateEncounterStatus(int BookingID, string BookingStatus);
and in the class
[WebInvoke(Method = "POST",
ResponseFormat = WebMessageFormat.Json,
UriTemplate = "UpdateEncounterStatus/{BookingID}/{BookingStatus}")]
public void UpdateEncounterStatus(int BookingID, string BookingStatus)
but when call it , I get
Operation 'UpdateEncounterStatus' in contract 'IPMA' has a path variable named 'BookingID' which does not have type 'string'. Variables for UriTemplate path segments must have type 'string'.
and when change the parameter to string I got
method not allowed
any idea how to fix that
You can use only string types for the parameters that comes in the route of UriTemplate. In your example BookingID is integer and it comes in the route so it won't work. If you move BookingID to querystring them things will work.
See this thread for more details.
I created a REST GetTime Service in WCF and the service returns JSON as the response message. Also the WebMessageBodyStyle is set to wrapped so it would have an ID associated with that data it returns. But when I use Fiddler to test my service the response string is:
{"GetTimeResult":"2010614104013"}
As the response above the ID of the string is GetTimeResult, I'm wondering is there any way on changing that bit of test to timestamp. So it looks like this:
{"timestamp":"2010614104013"}
Cheers.
If you are using the DataContract/DataMember attributes in your code, you add a name (as well as some other named parameters).
[DataMember(Name = "timestamp")]
public string GetTimeResult
As pointed out in this article, suppose you are not using a data member explicitly in a data contract and want to return, say, a timestamp as a simple string for the response. Just use the annotation [return: MessageParameter(Name = "timestamp")] with your operation contract method:
[OperationContract]
[WebInvoke(Method = "GET", UriTemplate = "/timestamps", ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped)]
[return: MessageParameter(Name = "timestamp")]
string GetStringTimestamp();
When using the following interface to talk to PHP from .NET, .NET builds the request body XML with parameter names barcode and branch. The parameter names should be Barcode and Branch. Yes, the PHP server is case sensitive.
Am I forced to capitalise my parameter names? or can I specify names using attributes?
Many Thanks

[ServiceContract]
public interface IStockEnquiryService
{
[OperationContract]
[WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Wrapped, ResponseFormat = WebMessageFormat.Xml, UriTemplate = "")]
Branches GetStockInfo(string barcode, string branch);
}
Try applying the MessageParameterattribute to the method arguments and specify the right case in its Name property.
I am using RESTful WFC's WebInvoke and WebGet attribute classes. In the UriTemplate parameter I want to capture a variable which includes the period character. How do I do so?
So
[WebInvoke(Method = "PUT", UriTemplate = "{id}")]
[OperationContract]
TItem UpdateItemInXml(string id, TItem newValue);
I would like it to match the url:
http://service.svc/A.1
I couldn't find a way to do so. The solution I implemented was to base64 encode the id in the URL.
