title: Why aren't all file templates that are available in the Add New Item dialog available in the New File dialog?
body: <p>In Visual Studio, if I have a solution open and choose File > New, the New File dialog provides me with a number of templates. However, if I, say, have an ASP.NET MVC project open, right click it and choose Add > New Item, the Add New Item shows <em>way</em> more item templates. For instance, I can add a new JSON file to my project this way, but I can't just create a new JSON file via File > New, because the template isn't available there.</p>
  
  <p>I often want to just create a one-off JSON file to see some proper formatting and coloring, and basically mess around with it, but then discard it without saving it. With Add New Item, it creates a new file and checks my project out from source control, which is too much hassle to correct if you just want to see some JSON code with proper formatting.</p>
