Direttamente dal blog di Martin Woodward un interessante articolo che ci spiega la reale differenza
tra Checkout e Get Latest in Team System, SourceSafe e PVCS.
"If you are using the source control features in Team
System then checkout means “Tell the server I want to edit this file and mark
that file as writeable in my file system”, at the same time that you check-out
the file you also get an option to lock the file using one of three lock types
(none, check-out and check-in)."
