I finally dug up the obscure command from MSDN that fixes this: ServicePointManager.DnsRefreshTimeout = 0; As I unwound all the weird things I’d tried previously, I discovered one other setting that I need along with the one above; on the request object, turn off keep-alive: request.KeepAlive = false;
You can use ReadAsStringAsync() method, then get the result using await statement or Result property: StringContent sc = new StringContent(“Hello!”); string myContent = await sc.ReadAsStringAsync(); //or string myContent = sc.ReadAsStringAsync().Result;

Here is an example: private async Task<System.IO.Stream> Upload(string actionUrl, string paramString, Stream paramFileStream, byte [] paramFileBytes) { HttpContent stringContent = new StringContent(paramString); HttpContent fileStreamContent = new StreamContent(paramFileStream); HttpContent bytesContent = new ByteArrayContent(paramFileBytes); using … Read more
If you’re using the HttpClient class, then you’ll get a HttpResponseMessage back. This class has a useful property called IsSuccessStatusCode that will do the check for you. using (var client = new HttpClient()) { var response = await client.PostAsync(uri, content); if (response.IsSuccessStatusCode) { //… } } In case you’re curious, this property is implemented as: … Read more
The idiomatic usage of EnsureSuccessStatusCode is to concisely verify success of a request, when you don’t want to handle failure cases in any specific way. This is especially useful when you want to quickly prototype a client. When you decide you want to handle failure cases in a specific way, do not do the following. … Read more
