It happens very often, during the development, to have some objects that are returned by some API and of which we want to create a class.
If the object are big with a lot of subnodes, it should be a long activity and, first of all, very annoying.
The Visual Studio team improved this feature in the last version of the IDE.
Create an empty class or just a file with the namespace declaration.
Then you can copy your JSON into the clipboard and in Visual Studio go to Edit -> Paste Special -> Paste JSON as Classes
This feature is very fast right now. With the previous version of Visual Studio, sometimes, you had issues to create a class from a big JSON file.
By default this command is not associated to any keyboard shortcut.
In my environment I configured that from the menu Tools -> Options.
I choosen Ctrl+V, Ctrl+J but you can choose your favourite shortcut for this special action.
