Hi guys
I have the following:
[ServiceContract]
[ServiceKnownType(typeof(ActionParameters))]
[ServiceKnownType(typeof(SportProgram))]
[ServiceKnownType(typeof(ActionResult<SportProgram>))]
public interface ISportProgramBl
{
[OperationContract]
IActionResult<ISportProgram> Get(IActionParameters parameters);
}
When I run the Get method I get the following error:
There was an error while trying to serialize parameter http://tempuri.org/%3AGetResult. The InnerException message was 'Type 'PPS.Core.DomainModel.Support.Action.ActionResult`1[ [PPS.Core.DomainModel.SportProgram.ISportProgram, PPS.Core.DomainModel, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]]' with data contract name 'ActionResultOfanyType: http://schemas.datacontract.org/2004/07/PPS.Core.DomainModel.Support.Action' is not expected. Add any types not known statically to the list of known types - for example, by using the KnownTypeAttribute attribute or by adding them to the list of known types passed to DataContractSerializer.'. Please see InnerException for more details.
From this error I can see that it can resolve ActionResult but it can't resolve ISportProgram even though I have ServiceKnownType(typeof(ActionResult < SportProgram >)) on my service interface...
Note this is the Reference stub that is generated looks like this, so I can see that the known types are being brought across correctly:
[System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "3.0.0.0")]
[System.ServiceModel.ServiceContractAttribute(ConfigurationName="SportProgramStb.ISportProgramBl")]
public interface ISportProgramBl {
[System.ServiceModel.OperationContractAttribute(Action="http://tempuri.org/ISportProgramBl/Get", ReplyAction="http://tempuri.org/ISportProgramBl/GetResponse")]
[System.ServiceModel.ServiceKnownTypeAttribute(typeof(PPS.Core.DomainModel.SportProgram.SportProgram))]
[System.ServiceModel.ServiceKnownTypeAttribute(typeof(PPS.Core.DomainModel.Support.Action.ActionParameters))]
[System.ServiceModel.ServiceKnownTypeAttribute(typeof(PPS.Core.DomainModel.Support.Action.ActionResult<PPS.Core.DomainModel.SportProgram.SportProgram>))]
object Get(object parameters);
}
Why is this going wrong???? Note its getting through the WCF service correctly... but it throws the exception when the result is returned.
Lastly ActionResult looks like this:
public interface IActionResult<T>
{
T Result { get; set; }
}
