Using Visual Studio AS Git Merge Tool

.gitconfig

[diff]
	tool = vsdiffmerge
[difftool]
	prompt = true
[difftool "vsdiffmerge"]
	cmd = \"C:\\Program Files (x86)\\Microsoft Visual Studio 12.0\\Common7\\IDE\\vsdiffmerge.exe\" \"$LOCAL\" \"$REMOTE\" //t
	keepbackup = false
	trustexistcode = true
[merge]
	tool = vsdiffmerge
[mergetool]
	prompt = true
[mergetool "vsdiffmerge"]
	cmd = \"C:\\Program Files (x86)\\Microsoft Visual Studio 12.0\\Common7\\IDE\\vsdiffmerge.exe\" \"$REMOTE\" \"$LOCAL\" \"$BASE\" \"$MERGED\" //m
	keepbackup = false
	trustexistcode = true

For VS2017:

cmd = "C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\CommonExtensions\Microsoft\TeamFoundation\Team Explorer\vsdiffmerge.exe"

I found the following to work for VS 2017:

[difftool "visualstudio"]
    cmd = 'C:/Program Files (x86)/Microsoft Visual Studio/2017/Enterprise/Common7/IDE/CommonExtensions/Microsoft/TeamFoundation/Team Explorer/vsdiffmerge.exe' $LOCAL $REMOTE Source Target //ignorespace //t
[mergetool "visualstudio"]
    cmd = 'C:/Program Files (x86)/Microsoft Visual Studio/2017/Enterprise/Common7/IDE/CommonExtensions/Microsoft/TeamFoundation/Team Explorer/vsdiffmerge.exe' $LOCAL $REMOTE $BASE $MERGED //ignorespace //m
    trustExitCode = true

So is it "$REMOTE\" \"$LOCAL\" or "$LOCAL" "$REMOTE" ? Example shown by @kmcginnes seems more consistent? Or does it even matter?

Anybody?

Is there any way to make it work with dir diff? git difftool --dir-diff

Should trustexistcode exist not be trustexitcode exit ?

For Visual Studio 2019 Professional:

[diff]
tool = vsdiffmerge
[difftool]
prompt = true
[difftool "vsdiffmerge"]
cmd = 'C:/Program Files (x86)/Microsoft Visual Studio/2019/Professional/Common7/IDE/CommonExtensions/Microsoft/TeamFoundation/Team Explorer/vsdiffmerge.exe' $LOCAL $REMOTE Source Target //ignorespace //t
keepbackup = false
trustexistcode = true

[merge]
tool = vsdiffmerge
[mergetool]
prompt = true
[mergetool "vsdiffmerge"]
cmd = 'C:/Program Files (x86)/Microsoft Visual Studio/2019/Professional/Common7/IDE/CommonExtensions/Microsoft/TeamFoundation/Team Explorer/vsdiffmerge.exe' $LOCAL $REMOTE $BASE $MERGED //ignorespace //m
keepbackup = false
trustexistcode = true

For Visual Studio 2019 Enterprise:
[diff]
