ReSharper 4 has been released by JetBrains. I blogged about it previous here so I won’t go over lots of old ground. Just as a reminder, this version supports C# 3, including LINQ. Very much recommended as a tool. If you want to try it out then there’s a 30 day free trial. Additionally they’ve started a partner scheme whereby existing licencees (including me) can introduce people to the tool by way of a 60 day trial with discounts to licence costs should those people buy a licence at the end. So get in touch if you want to give it a go.
