WCF Service Returning Method Not Allowed

Question

In the process of developing my first WCF service and when I try to use it I get  Method not Allowed  with no other explanation    I ve got my interface set up with the ServiceContract and OperationContract        OperationContract      void FileUpload UploadedFile file     Along with the actual method       public void FileUpload UploadedFile file        To access the Service I enter http   localhost project myService svc FileUpload but I get the  Method not Allowed  error  Am I missing something

The basic intrinsic types  e g  byte  int  string  and arrays  will be serialized automatically by WCF  Custom classes  like your UploadedFile  won t be    So  a silly question  but I have to ask it      is UploadedFile marked as a  DataContract   If not  you ll need to make sure that it is  and that each of the members in the class that you want to send are marked with  DataMember     Unlike remoting  where marking a class with  XmlSerializable  allowed you to serialize the whole class without bothering to mark the members that you wanted serialized  WCF needs you to mark up each member   I believe this is changing in  NET 3 5 SP1      A tremendous resource for WCF development is what we know in our shop as  the fish book   Programming WCF Services by Juval Lowy  Unlike some of the other WCF books around  which are a bit dry and academic  this one takes a practical approach to building WCF services and is actually useful  Thoroughly recommended

I ve been having this same problem for over a day now - finally figured it out  Thanks to  Sameh for the hint   Your service is probably working just fine  Testing POST messages using the address bar of a browser won t work  You need to use Fiddler to test a POST message   Fiddler instructions    http   www ehow com how 8788176 do-post-using-fiddler html

It sounds like you re using an incorrect address      To access the Service I enter http   localhost project myService svc FileUpload   Assuming you mean this is the address you give your client code then I suspect it should actually be   http   localhost project myService svc

If you are using the  WebInvoke Method  GET    attribute on the service method  make sure that you spell the method name as  GET  and not  Get  or  get  since it is case sensitive  I had the same error and it took me an hour to figure that one out

Only methods with WebGet can be accessed from browser IE   you can access other http verbs by just typing address  You can either try Restful service startup kit of codeples or use fiddler to test your other http verbs

Your browser is sending an HTTP GET request  Make sure you have the WebGet attribute on the operation in the contract    ServiceContract  public interface IUploadService        WebGet         OperationContract      string TestGetMethod       This method takes no arguments  returns a string  Perfect for testing quickly with a browser        OperationContract      void UploadFile UploadedFile file      This probably involves an HTTP POST request  Not so easy for a quick browser test
