I have always been able to drag source code files into the Visual Studio editor to open them. This is very convenient but lately it no longer works.
I thought the issue was my upgrading to VS2017 but after reading several similar questions here on Stack Overflow, I understand that the issue is probably that I'm running Visual Studio 2017 in Admin mode but since explorer is not run in admin mode Windows 10 apparently prevents dragging files from one user account to another to be opened via drag and drop.
That's all well and good. But the solution outlined here Drag & Drop files into Visual Studio doesn't work involves control panel UI for Windows 8 and that don't exist in the same place in Windows 10 and I can't seem to find them anywhere in Windows 10.
Another similar question, Visual Studio does not let me drag drop items into it? has an accepted answer of installing VS Commands for VS 2012 which provides features to deal with the issue. But when I search online I'm unable to find a similar download for VS 2017.
Another highly upvoted answer to that same questions suggests running cmd.exe as administrator then running explorer.exe from there. The thought being that when explorer.exe is ran this way it will be ran as administrator and then drag and drop to VS 2017 running as administrator should work. But I tried this and alas, it still doesn't work to drag a file (in my case AppSettings.json) into VS2017 from this special explorer window and have it open. Using a tip from one of the answers below, used task manager to see if this approach resulted in explorer.exe running with elevated privs and it did not.
All suggestions welcome.
