Having used Resharper for about 2 months I can definitely recommend it.
It’s a hard one to describe because as soon as you mention the words “Productivity” and “Tool” people tend to switch off.
Simply put, it enhances the VS2005 IDE and makes common tasks much more straightforward.
I am primarily using it with C# although VB.NET is partially supported and am finding it saves a lot of time.
Some of it’s features include:
- Improved intellisense
- Lots of refactorings
- Templates (File and code)
- Code Analysis
- On-The-Fly error checking (for c#)
