title: Disable lightweight solution load prompt
body: <p>In VS2017 lightweight solution load is disabled by default and since I don't want it I am happy. BUT there is an annoying prompt which prompts me to enable it when I load a solution with a "Large" number of projects.</p>
  
  <p>Is it possible to disable this prompt, so I do not enable it by accident ?</p>
  
  <p>I have searched Tools -> options and the registry to no avail. Also what is a "large" number of projects I have not been able to find the number. Perhaps if one could raise the number to say 100000 then the prompt would never appear.</p>
