The question relates to where can one customise the rule set for the new Visual Studio 2015 Light Bulb or Quick Actions feature.

The warning message given is: <blockquote> IDE0001 Name can be simplified. </blockquote> <img src="https://i.stack.imgur.com/PF6hI.png" alt="Light bulb feature">

<code>Tools</code> -> <code>Options</code> -> <code>Text Editor</code> -> <code>C#</code> -> <code>Code Style</code> Then untick the following: <blockquote> Prefer intrinsic predefined type keyword in member access expressions </blockquote> <img src="https://i.stack.imgur.com/btz1f.png" alt="enter image description here">
