I just received version 5 today, and in the past I recall advice saying to remove version 3 and install the new version. Are there any benefits in doing so?
Once I have the new version installed, are there any pit fall I should be aware of and look out for? My current development stage is my classes and a few forms, not a whole lot of rework, but any advice will be appreciated. And finally, is there much of a difference between the versions and what can I expect.
