I am facing an issue with two different endpoints in my single asp.net app. Basically, the issue is that one of the endpoints does not allow asynchronous methods in the page and the other endpoint does. If I run the app one endpoint will ask me to have an asynchronous asp.net page, but the other one crashes and vice versa. 

```
public async Task<AirtableListRecordsResponse> RetrieveRecord()
    {
        string MyProductID = ProductID;
        string baseId = "00000000000xxxx";
        string appKey = "00000000000xxxx";
        var records = new List<AirtableRecord>();
        using (AirtableBase airtableBase = new AirtableBase(appKey, baseId))
        {
            Task<AirtableListRecordsResponse> task = airtableBase.ListRecords(tableName: "efls", filterByFormula: ProductID);

            AirtableListRecordsResponse response = await task;
            if (!response.Success)
            {
                string errorMessage = null;
                if (response.AirtableApiError is AirtableApiException)
                {
                    errorMessage = response.AirtableApiError.ErrorMessage;
                }
                else
                {
                    errorMessage = "Unknown error";
                }
                // Report errorMessage
            }
            else
            {

                records.AddRange(response.Records.ToList());
                var record = response.Records;
                //offset = response.Offset;

                //var record = response.Record;
                foreach (var item in record)
                {
                    foreach (var Fields in item.Fields)
                    {
                        if (Fields.Key == "pdfUrl")
                        {
                            string link = Fields.Value.ToString();
                            MyLink = Fields.Value.ToString();
                        }

                    }
                }
                // Do something with your retrieved record.
                // Such as getting the attachmentList of the record if you
                // know the Attachment field name
                //var attachmentList = response.Record.GetAttachmentField(YOUR_ATTACHMENT_FIELD_NAME);
            }
            return response;
        }
    }

```

This is the asynchronous method which asks for an asynchronous page, the other contains a strong structure and it cannot be changed for any reason. Is there any way to make them work together?

I am using airtable.com api by the way.

Thanks in advance.
