UriTemplateTable does not support multiple templates that have equivalent path as template '/TasteList?TokenNo={TokenNo}' but have different query strings, where the query strings cannot all be disambiguated via literal values. See the documentation for UriTemplateTable for more detail.

the code are below :

C#

[OperationContract(Name = "GetAllTaste")]
        [WebInvoke(Method = "GET", UriTemplate = "/TasteList?TokenNo={TokenNo}", BodyStyle = WebMessageBodyStyle.WrappedRequest,
                    RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]
        TasteModel[] TasteList(string TokenNo);

        [OperationContract(Name = "GetClosestTaste")]
        [WebInvoke(Method = "GET", UriTemplate = "/TasteList?TokenNo={TokenNo}&Latitude={Latitude}&Longitude={Longitude}&Distanse={Distanse}", BodyStyle = WebMessageBodyStyle.WrappedRequest,
                    RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]
        TasteModel[] TasteList(string TokenNo, string Latitude, string Longitude, string Distanse);

        [OperationContract(Name = "GetTasteByLocation")]
        [WebInvoke(Method = "GET", UriTemplate = "/TasteList?TokenNo={TokenNo}&EncryptedLocationID={EncryptedLocationID}", BodyStyle = WebMessageBodyStyle.WrappedRequest,
                    RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]
        TasteModel[] TasteList(string TokenNo, string EncryptedLocationID);

        [OperationContract(Name = "TasteList")]
        [WebInvoke(Method = "GET", UriTemplate = "/TasteList?TokenNo={TokenNo}&EncryptedLocationID={EncryptedLocationID}&Latitude={Latitude}&Longitude={Longitude}&Distanse={Distanse}", BodyStyle = WebMessageBodyStyle.WrappedRequest,
                    RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]
        TasteModel[] TasteList(string TokenNo, string EncryptedLocationID, string Latitude, string Longitude, string Distanse);

hi Shmuel Zang
Thanks for the solution, but i sorted it using another technique that is :
I used post method.

C#

[OperationContract(Name = "TasteList")]
        [WebInvoke(Method = "POST", UriTemplate = "/TasteList",
                   RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]
        TasteModel TasteList(TasteModel model);

See this link: http://stackoverflow.com/questions/23049915/uritemplatetable-does-not-support-multiple-templates-that-have-equivalent-path-a.

Try to change the beginning of the UriTemplate of each operation to point to the appropriate path. (Instead of /TasteList use: /GetAllTaste, /GetClosestTaste, etc...)
