How to switch off solution wide analysis in Visual Studio 2015?

Question

On the PC of my collegue Visual Studio 2015 displays a message sometimes:

Low memory detected. Solution wide analysis is switched off.

Answer 1

To disable full solution analysis in Visual Studio 2015, go to Tools -> Options -> Text Editor -> C# -> Advanced, and uncheck the "Enable full solution analysis" checkbox.

Note that after installing the latest version of VS2015 Update 2, this settings is now disabled by default.
