Don’t use UriTemplate = "/MethodName/Param1/{Param1}/Param2/{JsonObject} for Json input with WCF Service
When building Ajax-enabled WCF service that expect a Json object as input then the following would not work
[OperationContract, WebGet(ResponseFormat = WebMessageFormat.Json, UriTemplate = "/Methodname/jsonvariable/{jsonvariable}/param2/{param2}")]
public void MethodName(string jsonvariable, string param2)
{
}
Where jsonvariable is a json object passed through jQuery (or ASP.NET Ajax) to a WCF service that looks like this
[{"Name":"za","Email":zubairdotnet@hotmail.com}]
After spending a while I figured out that the following UriTemplate should be used instead
[OperationContract, WebGet(ResponseFormat = WebMessageFormat.Json, UriTemplate = "/Methodname/?jsonvariable={jsonvariable}¶m2={param2}")]
public void MethodName(string jsonvariable, string param2)
{
}
