Today, I stumbled across a really neat feature in Visual Studio 2015 that gives you the ability to create a strongly-typed C# class directly into your class library. I'm amazed that I've happened to overlook this key feature since Visual Studio 2012!
Better late than never.
In the past, when consuming large JSON data-structures, I normally head off to http://json2csharp.com to help me get the initial class objects generated, which works a treat. I've blogged about my experiences using json2csharp here.
The strongly-type class generator feature is hidden away in a place I would never have thought to look - Edit > Paste Special, where you will be given the option to either generate a class object based on XML or JSON. But it's in there for a reason.
All that needs to be done now is to either copy some XML or JSON ready to paste into a newly created class. I do find the generated output quite untidy, but this is a great starting point to generating complex data structures.
