When I first add a project to source control(GIT) it will show all of the files and everything will be peachy. I can continue to work for about 30mins-1hr and all of the change
My Visual Studio "Source Control - Git" log kept complaining about a locked file from my SQL project. A .jfm file. Added it to .gitignore and then stuff worked.
So check your Git log when your solution shows no changes no matter what you change.
