Question

当我在ServiceStack中启用AutoQuery功能时，出现Autogeneration of WSDL failed错误。

显示以下异常：

System.Runtime.Serialization.InvalidDataContractException: 
Type 'ServiceStack.QueryResponse`1[T]' cannot be exported as a schema type because it is an open generic type. 
You can only export a generic type if all its generic parameter types are actual types.
   at System.Runtime.Serialization.DataContractSet.EnsureTypeNotGeneric(Type type)
   at System.Runtime.Serialization.XsdDataContractExporter.Export(ICollection`1 types)
   at ServiceStack.XsdUtils.GetXmlSchemaSet(ICollection`1 operationTypes)
   at ServiceStack.Metadata.XsdGenerator.ToString()
   at ServiceStack.Metadata.WsdlMetadataHandlerBase.GetWsdlTemplate(XsdMetadata operations, String baseUri, Boolean optimizeForFlash, String rawUrl, String serviceName)
   at ServiceStack.Metadata.WsdlMetadataHandlerBase.Execute(IRequest httpReq, IResponse httpRes)

AutoQuery使用的QueryResponse类型似乎是泛型类型。

请求对象：

[Route("/Data/ApplicationLog")]
public class AutoQueryApplicationLog : QueryBase<ApplicationLog>
{
    public long[] Id { get; set; }
    public string[] LogLevel { get; set; }
    public string[] Source { get; set; }
    public string[] Message { get; set; }
    public string[] Host { get; set; }
    public string[] Type { get; set; }
    public string[] Logger { get; set; }
    public string[] CreatedBy { get; set; }
    public DateTime? CreatedDateGreaterThanOrEqualTo { get; set; }
}

响应对象：

[DataContract(Name = "ApplicationLog", Namespace = "http://Rx30.Services.aa.is/types")]
public class ApplicationLog
{
    [PrimaryKey]
    [AutoIncrement]
    [DataMember]
    public long Id { get; set; }

    [DataMember]
    public string LogLevel { get; set; }

    [DataMember]
    public string Source { get; set; }

    [DataMember]
    public string Message { get; set; }

    [DataMember]
    public string StackTrace { get; set; }

    [DataMember]
    public string Host { get; set; }

    [DataMember]
    public string Type { get; set; }

    [DataMember]
    public string Logger { get; set; }

    [DataMember]
    public DateTime CreatedDate { get; set; }

    [DataMember]
    public string CreatedBy { get; set; }
}

有没有办法纠正这个错误？

现在应该是fixed with this commit，它将位于now available on MyGet的ServiceStack的 v4.0.24 + 版本中。

使用ServiceStack AutoQuery功能会导致WSDL自动生成失败错误
