Is File.ReadAllText locking the file?

[Symbai]

I want to read all text of a file but there is a small chance that something else is writing/reading to/from it at the same time. Can I use ReadAllText and if not, what else should I use instead?

ReadAllText specifies FileShare.Read. It could be use concurrently with any other operation using a compatible file lock.
