WCF服务.Net Core 2.2的Taleo SOAP投影查询返回了100多个字段投影的错误

Question

我已将WCF连接服务添加到我的.Net Core 2.2项目中。 我正在使用参考文件中创建的Projection类连接SOAP服务。 当我在投影中添加100多个字段时，它返回并出错：

查询不符合性能指标要求。 属性“ perfo.max.projection.field.count”为100，但提供的查询出现了118次。

我已将投影添加到findPartialEntitiesRequest方法中，如下所示：

                var findRequest = new findPartialEntitiesRequest
                {
                    query = new sqxmlQuery
                    {
                        query = new query
                        {
                            alias = "Find requisition",
                            projectedClass = ApplicationClassName,
                            projections = new queryProjections { projection = TaleoServiceProjections.GetApplicationRequisitionProjection("").ToArray() },
                            filterings = new queryFilterings
                            {
                                filtering = new[] { new filtering {
                                    Item = new equal {
                                        Items = new object[] {
                                            new field { path = "Requisition,ContestNumber" },
                                            new @string { Value = contestNumber }
                                        }}}}
                            }
                        }
                    },
                    mappingVersion = _settings.MappingVersion,
                    attributes = new string2stringMapEntry[] { }
                };

                var pagedResults = await client.findPartialEntitiesAsync(findRequest);

创建一个类“ TaleoServiceProjections”，在其中我返回的字段将作为新投影的产量：

    public static IEnumerable<projection> GetApplicationRequisitionProjection(string prefix = "Applications,")
    {
        yield return new projection() { Item = new field() { path = prefix + "BillRate" } };
        yield return new projection() { Item = new field() { path = prefix + "ChargeSalesTax" } };
        ......
        foreach (var cn in GetApplicationRequisitionCandidateProjection("Candidate,"))
            yield return cn;
    }
    public static IEnumerable<projection> GetApplicationRequisitionCandidateProjection(string prefix = "")
    {
        yield return new projection() { Item = new field() { path = prefix + "Access_20End_20Date" } };
        yield return new projection() { Item = new field() { path = prefix + "ActiveApplicationCount" } };
        ........
    }

在WCF参考类中生成的“投影”类为：

任何帮助。 我正在使用Visual Studio 2019社区版
