One of my colleague suggested me WebRequest.Create actually sends a web request to the specified url and I don't have to use asynchronous web request in order to avoid waiting.
Is this true?
How ever I don't agree with him and when I showed him the documentation but he said that he has been calling WebRequest.Create to send requests.
I'm not sure if this is true as i don't have deep knowledge of .net
No, calls to GetResponse() on the created WebRequest is what actually issues the request.
From the docs:
The GetResponse method sends a request to an Internet resource and returns a WebResponse instance.
