Question: Every time you double-click a C# script file from the Project window, Unity prints the message below (or something very similar) to the console. What is a reasonable step in trying to solve this? Cannot start process because a file name has not been provided

  1. Search the Project windows for all script files and then rename all of them
  2. Set Visual Studio as the code default editor via the External Tools tab of the Preferences menu
  3. Ensure you have specified a Play mode tint color from the Colors tab of the Preferences menu
  4. Select the Script file, and then select Assets > Find references in Scene from the Application menu

Answer: The correct answer of the above question is Option B:Set Visual Studio as the code default editor via the External Tools tab of the Preferences menu
