Should this always be deleted, unconditionally?
There was a problem hiding this comment.
I would say yes, as the entire file is fully re-created (no update). This way it is ensured that the written file does not contain garbage after the expected content.
Maybe one could check whether the file exists, which is in my opinion useless as Delete() does not throw when the file does not exist.

This PR fixes #2257
Note 1: The first commit would also fix the issue but does not the IFileStream as an abstraction layer. The second commit does.
Note 2: The added unit test also succeeds without the fix :(. As far as I saw, this is because the
OpenWrite()function of theTestFileSystemclass does not behave the way as it documented in https://docs.microsoft.com/en-us/dotnet/api/system.io.file.openwrite?view=netcore-3.1 in regards to existing files.
