How do you completely disable the light bulb in Visual Studio 2015? It reminds me of Clippy.
To completely disable the light bulb :
For Visual Studio 2015, you can add this key in the registry :
[HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\14.0\Roslyn\Internal\OnOff\Features] "Squiggles"=dword:00000000
For Visual Studio 2017, you can add this key in the registry :
[HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\15.0_xxxxxxxx\Roslyn\Internal\OnOff\Features] "Squiggles"=dword:00000000
with "xxxxxxxx" being a random string.
