Using AVR for .NET to enable AVR Classic to make HTTP requests

Many applications, both Windows and Web, need to connect to the Internet to send or receive data. ASNA Visual RPG Classic apps do not intrinsically have the ability to make HTTP requests. This can be a crippling drawback when you have a legacy enterprise app for which you now have the requirement to send and/or receive data from the Internet. There are still a few third-party COM controls around that can enable AVR to make HTTP requests, but these controls are often troublesome and customers report that some no longer work. This article shows how to extend AVR Classic with AVR for .NET to enable the AVR Classic app to fetch data Json data with an HTTP request. We'll first a look at the AVR for .NET class library project responsible for making the HTTP request to fetch the Json then we'll take a look at the AVR Classic app that consumes that .NET class library. This article provides a simple example of fetching Json. Things like user authentication and product-worthy error handling are omitted--but both can be added.
