'Deserializing large JSON Objects from Web Service (Out of Memory)
I have a program that deserializes large objects from a web service. After a webservice call and a 200, the code looks like this.
JsonConvert.DeserializeObject<List<T>>(resp.Content.ReadAsStringAsync().Result).ToList()
Sometimes while running this process I will get an aggregate exception which shows an inner exception as out of memory. I can't determine if it is the process of reading in the string of JSON data (which is probably awfully large) or the Deserializing that is causing this issue. What I would like to do is break out the string and pull each JSON object back individually from the response and then deserialize it. I am just having trouble finding a way to only bring out one JSON object at a time from the response. Any suggestions are greatly appreciated!

https://docs.microsoft.com/en-us/xamarin/xamarin-forms/data-cloud/web-services/rest contains a warning:
Using the ReadAsStringAsync method to retrieve a large response can have a negative performance impact. In such circumstances the response should be directly deserialized to avoid having to fully buffer it.
