dotnet watch run watches the .git folder.

[StringEpsilon]

Describe the bug

The dotnet watch run command watches the .git folder of my project, sometimes even recompiling due to this error:

Unable to apply hot reload, restart is needed to apply the changes.

From a simple git stash / git stash pop:

dotnet watch ⌚ Files added: ./.git/objects/3c/tmp_obj_S92RQS, ./.git/index.lock, ./.git/index, ./.git/objects/3c/82172b9f73e35b3b42e3653c719df4db9726ec

dotnet watch ⌚ No hot reload changes to apply.

dotnet watch ⌚ Files added: ./.git/index.lock, ./.git/index, ./.git/AUTO_MERGE, ./test, ./.git/AUTO_MERGE.lock
dotnet watch ⌚ No hot reload changes to apply.

To Reproduce

1. Create a new test application in a new git repository where the .csproj file is located in the git root folder.
2. touch test
3. git add test
4. dotnet watch run
5. git stash -S

Now observe the dotnet watch console output.

@tmat, looks like this is a dotnet watch issue.

@StringEpsilon Could you share the full --verbose output for the case when you get Unable to apply hot reload, restart is needed to apply the changes. error?

[StringEpsilon]

@tmat I have only had that happen once so far from changes in the .git directory, which was when I was testing the reproduction steps for this issue.

If I find a way to provoke that reliably, I'll try to get the verbose output for it. But I'll not run --verbose for my everyday work to catch what turned out to be a fluke, hope you'll understand.

The main issue still stands tho.

@StringEpsilon Thanks. We can certainly special-case and exclude the .git directory, but there should be no difference in functionality. Just more console output.
