title: "Select Startup Item" command / drop-down not showing on Standard toolbar in Visual Studio
body: <p>Up until recently I could select the startup project (equivalent to right-clicking on the project in the solution explorer and choosing "Set as Startup Project") from the Standard toolbar with the "Select Startup Item" drop-down.  Now it's gone, yet the item is still checked under "Add or Remove Buttons".  </p>
  
  <p>The closest reference I could find is <a href="https://developercommunity.visualstudio.com/content/problem/373582/select-startup-item-not-showing-in-standard-toolba.html" rel="noreferrer">this</a>, but the solution doesn't match my situation because I have more than one project and this is happening no matter which solution is loaded.</p>
  
  <p>Please help me figure out what is going on.</p>
