Description
This makes things work better in a source-tarball build, where there may be a .git directory somewhere in our parent directories but it's for a different repo than vstest. In a situation like that a plain
git apply
will (silently!) ignore patches because they wont apply to the unrelated repository. That will (eventually) make the source-build fail.--work-tree
makes git directly use the directory that we care about.Related issue
See dotnet/source-build#2445 for more details.
