In this chapter we explored using web APIs to retrieve data from remote servers. We saw how to use the
WebRequest object to make this task approachable. We also revisited ideas you’ve seen in prior courses like the
IDisposable interface and
using statements to work with unmanaged objects. We saw how to consume XML data we receive as a response from a web API.
We also discussed using
async methods to allow our programs to continue to respond to user input and incoming web requests while processing long-running tasks in parallel. Finally, we discussed RESTful routes, a standardized way of determining the routes for your web API.
