Question

我在执行Microsoft.OData.Client Service

时遇到以下错误

它只是提供异常IIS 8.0 Detailed Error - 404.0 - Not Found

但是当我使用浏览器尝试使用相同的服务时，它完全正常运行

我试图在执行 -

之后调用服务，例如跟随获取异常

MyDataServiceClient myDataServiceClient = new MyDataServiceClient(new Uri("http://localhost:64555/mydev"));
                var query = myDataServiceClient.AllLanguage;
                List<Language> languageList = query.ToList();

这里有什么问题？在WebApiConfig.cs

中

private static IEdmModel model = null;
  private static IEdmModel model = null;

        public MyDataServiceClient(Uri serviceRoot)
            : base(serviceRoot, DataServiceProtocolVersion.V3)
        {
            this.Format.LoadServiceModel = this.LoadServiceModel;
            this.Format.UseJson();
        }

        private Microsoft.Data.Edm.IEdmModel LoadServiceModel()
        {
            try
            {

                if (model == null)
                {
                    var metadataUri = this.GetMetadataUri();
                    var request = WebRequest.CreateHttp(metadataUri);

                    using (var response = request.GetResponse())
                    using (var stream = response.GetResponseStream())
                    using (var reader = System.Xml.XmlReader.Create(stream))
                    {
                        model = Microsoft.Data.Edm.Csdl.EdmxReader.Parse(reader);
                    }
                }
                return model;
            }
            catch (Exception exception)
            {

                return null;
            }
        }

给出错误：

解析EDMX文档时遇到以下错误： UnexpectedXmlElement：根元素的元素'edmx：Edmx'是意外的。根元素应该是Edmx。：（2,2）
