I am using Git on visual studio 2017 .
In our projects, for running in development mode ,some changes need to be done on some config files on our branch (created from Master Branch ).
Note : Those changes(which are in config files for running the project locally) need not to be push in upper branch.
As we know that Before taking latest from Master Branch in GIT ,we need to commit all changes .
Please suggest me , Is there any way that I can take Back up of Modified Files before taking Latest from Upper Branch or How can we take latest from Master Branch into our local branch if we have modified files in (Changes Tab of Team Explorer).
