title: How to create a .tfignore file?
body: <p>Visual Studio 2017 (v15.9.9).</p>
  
  <p>I can't seem to figure out how to create a .tfignore file.  If I do it manually, windows tells me I need to add a file name. And I am not seeing anywhere via the IDE to create one.</p>
  
  <p>I'm used to GIT, where I can right click on a pending check-in file (that has changed) and just select "Ignore". But I don't seem to have that option, despite the fact that all the results I find via Google tell me that I should.</p>
