You might need to build the project to get it to work.
See Code Editing ASP.NET Web Forms in Visual Studio 2013 | Microsoft Docs. (If it is missing then the point is that I am using an example provided by Microsoft.). In Refactoring and Renaming see To extract a method in a C# page. When I follow the instructions I cannot find the feature to extract the code to a method. When I tried the Edit menu it said I did not have valid code. Then I built the project and the feature to extract the code was available and worked.
