How can I disable ReSharper in Visual Studio and enable it again?

I always forget how to do this and this is the top result on Google. IMO, none of the answers here are satisfactory.
So the next time I search this and to help others, here's how to do it and what the button looks like to toggle it:

• Make sure Resharper is currently enabled or the commands may fail.
• Open package manager console via the Quick Launch bar near the caption buttons to launch a PowerShell instance.
• Enter the code below into the Package Manager Console Powershell instance:

If you want to add it to the standard toolbar:

$cmdBar = $dte.CommandBars.Item("Standard") 
$cmd = $dte.Commands.Item("ReSharper_ToggleSuspended")
$ctrl = $cmd.AddControl($cmdBar, $cmdBar.Controls.Count+1)
$ctrl.Caption = "R#"

If you want to add it to a new custom toolbar:

$toolbarType = [EnvDTE.vsCommandBarType]::vsCommandBarTypeToolbar
$cmdBar = $dte.Commands.AddCommandBar("Resharper", $toolbarType)
$cmd = $dte.Commands.Item("ReSharper_ToggleSuspended")
$ctrl = $cmd.AddControl($cmdBar, $cmdBar.Controls.Count+1)
$ctrl.Caption = "R#"

If you mess up and need to start over, remove it with:

$ctrl.Delete($cmdBar)
$dte.Commands.RemoveCommandBar($cmdBar)

In addition to adding the button, you may wish to add the keyboard shortcut
ctrl+shift+Num -, ctrl+shift+Num - that is: ctrl+shift+-+-

EDIT: Looks like StingyJack found the original post I found long ago. It never shows up when I do a google search for this

If resharper is completely missing from the options menu, it could be because the extension itself has been disabled.

In Visual Studio 2017 ReSharper 2018.X.X can be enabled and disabled by going to Help > Manage Visual Studio Performance. Then select JetBrains ReSharper ... under Extensions.

In Visual Studio 2019, you would go under Extensions->Manage Extensions->Installed

In case the solution did not help to just suspend resharper (STRG+R, STRG+R did still not work for example) I decided to disable the plugin and restart visual studio.

VisualStudio > Extras > Extensions > Resharper > Disable

Now Resharper supports Suspend & Resume argument at devenv.exe

(ReSharper 2019.2.3)

Run VS & Suspend R#:

devenv.exe /ReSharper.Suspend

Run VS & Resume R#:

devenv.exe /ReSharper.Resume

Here's an example usage:

For ReSharper 2017.2.2, go to ReSharper | Options | Product and features.

Very simple steps:

1. Go to Extensions → Manage Extensions
2. Click on Installed section at the top left and search for "resharper"

You will see disable button over the extension, click to it then restart Visual Studio and that's it!
