Git.Branch always gives [HEAD] for detached HEAD commit.

[ArkaHnat]

When I'm trying to use ThisAssembly.Git.Branch on detached head it always returns me [HEAD].
I didn't change any options.
When I run command git name-rev --refs=refs/heads/* --no-undefined --always SHA1 which is a default it gives correct result.
If my branch isn't detached ThisAssembly.Git.Branch also gives me correct result

And what would constitute "the correct result" for a Branch property where there's no branch checked out? (Unless I misunderstood the question).

@kzu correct result would be in this case the branch to which the commit belongs

A commit can belong to any number of branches.

The code that currently determines the branch can be seen at GitInfo.targets.

You can run your own target after that to detect your specific scenario with:

<Target Name="MyBranch" AfterTargets="_GitBranch" Condition="$(GitBranch) == '[HEAD]'">
   <Exec ... />
</Target>

Alternatively, consider testing this scenario and providing a PR that updates the git commands we issue to determine the branch.
