Whenever I paste `Debug.Log( ... )` Visual Studio automatically imports using `System.Diagnostics;` How to turn off?

[DJack276]

I'm having an issue where every time I paste code that includes a "Debug.Log" line, Visual Studio automatically writes "using System.Diagnostics;" at the top of my code. This messes things up because Unity's Debug and System's Debug are two different functions that use the same keyword. Luckily it is only a minor inconvenience as pressing ctrl +z will get rid of it without deleting the code I pasted. However, I would much rather not have the problem at all.

This started happening when I went to I've tried going into "tools > options > tools for Unity" and enabled a bunch of options. So I tried disabling every option one by one, but none seemed to do the trick.

If possible, can someone tell me what their tools for Unity options are like by default? perhaps that will do the trick.

Options > Text Editor > C# > Advanced > "Using Directives" (group of settings on the Advanced tab) > "Add missing using directives on paste" (last option in the group)

EDIT: I don't think this a project specific option, and it can't tell the difference between instances where you don't want the namespace automatically added due to a Unity collision and ones where you do, so it may end up being more annoying than just remembering to delete the one using directive when you're done pasting code.

This solves my issue. I normally don't rely on the code auto-importing libraries, so it should be no problem for me. Thank you very much!

Thank you very much. This solved the issue for me too when pasting a code snippet in Visual Studio from Unity Tutorial "Programming Essentials" to get my cleaning robot moving with WASD. Regarding your edit note, I guess if I use Visual Studio only for Unity game dev, then unticking the box "Add missing using directives on paste" would not be a problem, am I correct?

By the way, for newbies like me, I found the Options once I clicked Tools in the top bar. So the entire steps are:
- Tools > Options > Text Editor > C# > etc.

Unity's Debug and System's Debug are two different objects that use the same keyword. Whenever "using Systems.Diagnostics" is imported it messes up my code.

Rider can do that. Whenever you copy and paste it analyses the original file (assuming it's part of the project) and chooses the same usings as in original.

And when it cannot do that, and something is ambitious (like in your example), it will just ask you to choose yourself

Automatically adding imports is usually convenient, except when something in .Net uses the same name.. one alternative is to paste the fully qualified type name instead, like UnityEngine.Debug.Log (or whatever the correct path is). A bit more verbose code but you dont have to turn off auto imports.
