Question

我在运行时收到异常，我该怎么做才能解决它？

我将所有内容升级到最新版本。

 var query = q as System.Data.Services.Client.DataServiceQuery<T>;
                    if (continuationToken != null)
                    {
                        query = query.AddQueryOption("NextPartitionKey", continuationToken.PartitionKey);
                        if (continuationToken.RowKey != null)
                        {
                            query = query.AddQueryOption("NextRowKey", continuationToken.RowKey);
                        }
                    }
                    // i fall here with the concrete exception I mentioned above
                    var response = (System.Data.Services.Client.QueryOperationResponse<T>) query.Execute();
                    result = result.Union(response.ToList<T>());


Exception thrown: 'System.InvalidCastException' in Microsoft.Data.Services.Client.dll

Additional information: Unable to cast object of type 'System.Data.Services.Client.Providers.EdmEntityTypeWithDelayLoadedProperties' to type 'Microsoft.Data.Edm.IEdmComplexType'.

从Azure SDK 2.5升级到Azure SDK2.8.1
