i have visual studio 2017 solution 6 projects in. i right clicked on solution "add solution source control". i go team explorer / changes / commit all. works fine "commit abcde123 created locally. sync share changes server. (i don't want share changes server - i'm solo dev). the changes window still full of changes. offers take commit again - press - errors, presume because trying reach server isn't configured. "fatal: unexpected sequence in commit output.". the changes window still full. i have changed files - can't see changes made (e.g. right clicking , selecting "view history"). think may because checkin server failed. how can set git in visual studio work locally, not try , upload server , see local checkin having finished checking in? (i think has worked fine in past single project solutions).
