I have a webservice as below
<OperationContract()>
<Web.WebGet(UriTemplate:="/GetData?strErrMsg={strErrMsg}&chrErrFlg={chrErrFlg}", ResponseFormat:=WebMessageFormat.Json, BodyStyle:=WebMessageBodyStyle.Wrapped)> _
Function GetData(ByRef strErrMsg As System.Collections.Generic.List(Of String), ByRef chrErrFlg As String) As String
And I am trying to fetch it as
http://BedTypeMasterService.svc/GetData?strErrMsg="ff"&chrErrFlg="dd"
But it is giving following error
Operation 'GetData' in contract 'iBedTypeMaster' has a query variable named 'strErrMsg' of type 'System.Collections.Generic.List1[System.String]', but type 'System.Collections.Generic.List1[System.String]' is not convertible by 'QueryStringConverter'. Variables for UriTemplate query values must have types that can be converted by 'QueryStringConverter'.
Please help me out to solve this

My wcf reset service has only 2 contracts, one is working always and the other did not work.
Service Code:
Public Class BasicServ

End Function
Function Authorize(ByVal id As String, ByVal pw As String) Implements IBasicServ.Authorize
Dim c As New List(Of Guid)
For i = 0 To 10
c.Add(Guid.NewGuid)
Next
Return c
'Return Guid.NewGuid
End Function
End Class

While debugging/testing, I found that, if I return only 1 GUID in Authoriza method, it is working, but when I am sending a list of GUID, it is not working, and the SVClog file is not getting created. Could you please help me understand WCF REST service better. Thank you.
From above comments and few experiments, the solution for the question is that a return type is not compulsory if it is string, but if anything else, return type must be specified. Better if return type is provided always.
I migrated a web service to a WCF service. The service exposes two endpoints, one returns JSON and one returns SOAP.
The SOAP endpoint works as expected, but the response from the JSON endpoint is wrapped with the response object name - something that did not exist in the JSON response the web service I migrated from used to return.
I tried working with the BodyStyle property, but all I got is an exception: The body style 'Bare' is not supported by 'WebScriptEnablingBehavior'. Change the body style to be 'WrappedRequest'.
All my methods accept only POST requests.
This is how my service is configured:
<services>
<service name="MyService" behaviorConfiguration="MyServiceBehavior">
<endpoint address="" binding="basicHttpBinding" bindingNamespace="http://MyService.org/" contract="IMyService"/>
<endpoint address="json" behaviorConfiguration="JsonEndpointBehavior" binding="webHttpBinding" contract="IMyService" />

I am trying to increase maxReceivedMessageSize for my wcf odata service. I have an another web service which is posting values to my wcf service to insert values to sql. I am posting
{
A:1,
B:1,
C:3,
D:4,
}
this raised an error. The remote server returned an error: (400) Bad Request. If i post the value below, it inserted successfully.
{
A:1
}
so can somebody please help me how to fix this error please? There are examples on the web which are trying to modify web config like below but they dont suits me because i dont have a service contract.

I've been working in .NET for a while now, but I'm new to WCF. I'm trying to create my very first WCF service using JSON. I thought I would start really, really simple and then build from there. But I have somehow managed to screw up even the most simple of services. Here's what I've got so far.
Web.Config:
<?xml version="1.0"?>
<configuration>
<system.web>
<compilation debug="true" targetFramework="4.0" />
</system.web>
<system.serviceModel>
<services>
<service name="MarathonInfo.MarathonInfoService">
<endpoint address="http://localhost:10298/MarathonInfoService.svc" binding="webHttpBinding" contract="MarathonInfo.IMarathonInfo" />
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior>
<!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
<serviceMetadata httpGetEnabled="true"/>
<!-- To receive exception details in faults for debugging purposes, set the value below to true. Set to false before deployment to avoid disclosing exception information -->
<serviceDebug includeExceptionDetailInFaults="false"/>
</behavior>
</serviceBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="false" />
</system.serviceModel>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true"/>
</system.webServer>
</configuration>
Then, in the service file:
namespace MarathonInfo
{
public class MarathonInfoService : IMarathonInfo
{
public String GetData()
{
return "Hello World";
}
}
}
And in the interface:
namespace MarathonInfo
{
[ServiceContract]
public interface IMarathonInfo
{
[OperationContract]
[WebInvoke(Method = "GET", UriTemplate = "/GetData", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]
String GetData();
}
}
So, when I go to this url:
http://localhost:10298/MarathonInfoService.svc/GetData
I get this error:
The message with To
'http://localhost:10298/MarathonInfoService.svc/GetData' cannot be
processed at the receiver, due to an AddressFilter mismatch at the
EndpointDispatcher. Check that the sender and receiver's
EndpointAddresses agree.
I am able to execute the service just fine through Visual Studio in debug mode. But in the browser, I only get that error.
What am I doing wrong?
Thanks!

If you want to create a WCF WebHTTP Endpoint (i.e., one which returns JSON, and uses the [WebGet] / [WebInvoke] attributes), the endpoint needs to have the <webHttp/> behavior associated with it.
<system.serviceModel>
<services>
<service name="MarathonInfo.MarathonInfoService">
<endpoint address="http://localhost:10298/MarathonInfoService.svc"
binding="webHttpBinding"
contract="MarathonInfo.IMarathonInfo"
behaviorConfiguration="Web"/>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior>
<serviceMetadata httpGetEnabled="true"/>
<serviceDebug includeExceptionDetailInFaults="false"/>
</behavior>
</serviceBehaviors>
<endpointBehaviors>
<behavior name="Web">
<webHttp/>
</behavior>
</endpointBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="false" />
</system.serviceModel>
I am trying to create a wcf service that returns json. I have some problems with my config file and i also don't know how to test it.
<?xml version="1.0"?>
<configuration>

</system.web>
<system.serviceModel>

contract="IMetadataExchange" />
<host>
<baseAddresses>
<add baseAddress="http://192.168.1.31/ContactLibraryJSON" />
</baseAddresses>

<!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
<serviceMetadata httpGetEnabled="true"/>
<!-- To receive exception details in faults for debugging purposes, set the value below to true. Set to false before deployment to avoid disclosing exception information -->
<serviceDebug includeExceptionDetailInFaults="true"/>
</behavior>
</serviceBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
</system.serviceModel>

</system.webServer>
</configuration>
I still get
"Cannot add the behavior extension webhttp to the service behavior
names JSONEndpointBehavior because the underlying behavior type does
not implement the IServiceBehaviorInterface"
Contact is defined like :
[DataContract(Name="Contact")]
public class Contact
{
[DataMember(Name="FirstName")]
public string firstName=null;
[DataMember(Name="LastName")]
public string lastName=null;
[DataMember(Name="Email")]
public string email=null;
[DataMember(Name = "Age")]
public int age = 0;
[DataMember(Name = "Street")]
public string street=null;
[DataMember(Name = "City")]
public string city=null;
[DataMember(Name = "Country")]
public string country=null;
}
IContactService is defined like :
[ServiceContract]
public interface IContactServiceJSON
{
[OperationContract]
[WebGet(BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Json, UriTemplate = "")]
Contact GetContact();
}
The implementation of GetContact:
public Contact GetContact()
{
return new Contact()
{
firstName = "primulNume",
lastName = "alDoileaNume",
age = 33,
city = "Cluj",
country = "Romania",
email = "ceva#mail.com",
street = "Bizusa 8"
};
}
My service runs on another computer in my lan. Base address is like: http://192.168.1.xxx/ContactLibraryService. ContactLibraryService is hosted by IIS and is converted to an application.
You need to add the <webHttp/> to the list of endpoint behaviors. Also, the endpoint needs to use the webHttpBinding. And finally, to respond to GET HTTP requests, you need to use the WebGet attribute (instead of WebInvoke(Method="GET").
<system.serviceModel>
<services>
<service name="ContactLibrary.ContactLibrary">
<endpoint address=""
binding="webHttpBinding"
behaviorConfiguration="JSONEndpointBehavior"
contract="ContactLibrary.IContact"/>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
<endpoint address="ws"
binding="wsHttpBinding"
bindingConfiguration=""
contract="ContactLibrary.IContact" />
<host>
<baseAddresses>
<add baseAddress="http://localhost/ContactLibrary" />
</baseAddresses>
</host>
</service>
</services>
<behaviors>
<endpointBehaviors>
<behavior name="JSONEndpointBehavior">
<webHttp/>
</behavior>
</endpointBehaviors>
<serviceBehaviors>
<behavior>
<!-- To avoid disclosing metadata information,
set the value below to false and remove the metadata endpoint above before deployment -->
<serviceMetadata httpGetEnabled="true"/>
<!-- To receive exception details in faults for debugging purposes,
set the value below to true. Set to false before deployment
to avoid disclosing exception information -->
<serviceDebug includeExceptionDetailInFaults="true"/>
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
And the service contract:
[ServiceContract]
public interface IContact
{
[OperationContract]
[WebGet(BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Json, UriTemplate = "contact")]
Contact GetContact(int idContact);
}
It's not good that you have Service Contract IContact and Data Contact Contact. Rename Service Contract like IContactService.
<services>
<service name="ContactLibrary.ContactService">
<endpoint address="" binding="webHttpBinding" contract="ContactLibrary.IContactService" behaviorConfiguration="JsonBehavior" />
<host>
<baseAddresses>
<add baseAddress="http://localhost:8732"/>
</baseAddresses>
</host>
</service>
</services>
<behaviors>
<endpointBehaviors>
<behavior name="JsonBehavior">
<webHttp />
</behavior>
</endpointBehaviors>
</behaviors>
During Debug time (it looks you have WCF library), service address will be http://localhost:8732/contact
I think you missed bindings here you have to add webHttpBinding and basichttpbing under the bindings tab in system.serviceModel tag.
