Reason for ExtractMethodCodeRefactoringProvider encountered an error and has been disabled?

Question

I'm getting this error, when I'm trying to extract the method from code by using right-click on a selected code(Quick Actions and Refactoring) or Ctrl + ..

I'm using Visual Studio 2015. I'm able to refactor for other projects in a different solution. My solution has multiple projects, it's not working on all the projects under this solution.

I tried the same thing using Visual Studio 2010, this is working fine with a solution.

It's showing this error only in Visual Studio 2015.

so is this a bug in Visual Studio 2015? or I need to make some settings in Visual Studio or in code, solution or projects?, I never saw this error before with Studio 2015.

FYI: It's not a compilation error, It's just a warning, It's not stopping me to run the application or debug.
