I’ve just started using ReSharper with Visual Studio (after the many recommendations on SO). To try it out I opened up a recent ASP.NET MVC project. One of the first and most frequent things I’ve noticed it suggesting is to change most/all my explicit declarations to var instead. For example:
//From This:
MyObject foo = DB.MyObjects.SingleOrDefault(w => w.Id == 1);
//To This:
var foo = DB.MyObjects.SingleOrDefault(w => w.Id == 1);
and so on, even with simple types such as int, bool, etc.
Why is this being recommended? I don’t come from a computer science or .NET background, having “fallen into” .NET development recently, so I’d really like to understand what’s going on and whether it’s of benefit or not.
