IEnumerable vs List in response class, ServiceStack

I am not sure if this is a problem or not.

If I use List here, does it work as in root / xml / metadata? op = Competition and root / Competitions

[DataContract]
public class CompetitionsResponse : IHasResponseStatus
{
    [DataMember]

    public List<Competitions> Competitions { get; set; }

    //Auto inject and serialize web service exceptions
    [DataMember]
    public ResponseStatus ResponseStatus { get; set; }
}

HTTP / 1.1 200 OK Content-Type: application / xml Content-Length: length

<CompetitionsResponse xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.datacontract.org/2004/07/FSI.API.ServiceModel">
  <Competitions>
    <Competitions>
      <CompName>String</CompName>
      <CompType>String</CompType>
      <CompetitionID>0</CompetitionID>
    </Competitions>
  </Competitions>
  <ResponseStatus xmlns:d2p1="http://schemas.servicestack.net/types">
    <d2p1:ErrorCode>String</d2p1:ErrorCode>
    <d2p1:Errors>
      <d2p1:ResponseError>
        <d2p1:ErrorCode>String</d2p1:ErrorCode>
        <d2p1:FieldName>String</d2p1:FieldName>
        <d2p1:Message>String</d2p1:Message>
      </d2p1:ResponseError>
    </d2p1:Errors>
    <d2p1:Message>String</d2p1:Message>
    <d2p1:StackTrace>String</d2p1:StackTrace>
  </ResponseStatus>
</CompetitionsResponse>

But if I use "IEnumerable"

[DataContract]
public class CompetitionsResponse : IHasResponseStatus
{
    [DataMember]
    public IEnumerable<Competitions> Competitions { get; set; }

    //Auto inject and serialize web service exceptions
    [DataMember]
    public ResponseStatus ResponseStatus { get; set; }
}

A collection of contests disappeared from the meta page root / xml / metadata? op = Competition

HTTP/1.1 200 OK

Content-Type: application / xml Content-Length: length

<CompetitionsResponse xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.datacontract.org/2004/07/FSI.API.ServiceModel">
  <Competitions i:nil="true" />
  <ResponseStatus xmlns:d2p1="http://schemas.servicestack.net/types">
    <d2p1:ErrorCode>String</d2p1:ErrorCode>
    <d2p1:Errors>
      <d2p1:ResponseError>
        <d2p1:ErrorCode>String</d2p1:ErrorCode>
        <d2p1:FieldName>String</d2p1:FieldName>
        <d2p1:Message>String</d2p1:Message>
      </d2p1:ResponseError>
    </d2p1:Errors>
    <d2p1:Message>String</d2p1:Message>
    <d2p1:StackTrace>String</d2p1:StackTrace>
  </ResponseStatus>
</CompetitionsResponse>

ServiceStack uses the .NET XML DataContractSerializer under the hood for its XML serialization, which is the behavior of your vision. It also works with POCOs, that is, the [DataContract] and [DataMember] attributes are optional.

DTO (IMO ), , , . , IEnumerable, , info , .

. , XML , DTO - - AssemblyInfo.cs:

[assembly: ContractNamespace("http://schemas.servicestack.net/types",  
    ClrNamespace = "FSI.API.ServiceModel")]
