Paste JSON and XML as a Class
However, I'd rather be able to use this functionality without having to drag my mouse to the Edit menu. To support that, I added a keystroke combination for the underlying commands related to these menu choices.
If you want to do the same, first go to Tools | Options | Environment | Keyboard. To grab the commands, in the "Show commands containing" textbox, type in AsClasses and select one. Then, from the "Use new shortcut in" dropdown list, pick your language's editor (for example, CSharp Editor or Microsoft Visual Basic Editor). Now you can click in the "Press shortcut keys" textbox to select your shortcut key(s): Just press the keys you want to use. Finally, click the Assign button. Lots of people forget that step and just click the OK button at the bottom of the dialog (by "lots of people" I mean: me).
You probably don't want to override any existing shortcut keys so I'd recommend picking a "chord": two or more keys pressed sequentially while holding down one of the control keys (the dialog box will tell you if you pick a shortcut that's already in use). I picked Ctrl+K, J for pasting JSON and Ctrl+K, M for pasting XML (Ctrl+K, X was already taken for inserting snippets and, who knows, I might start using that some day).
