Readability is one of the reasons I try to avoid the use of the 'var' keyword in C#. It's useful in object instantiation, e.g. FooFizzBuzzProvider bar = new FooFizzBuzzProvider() vs var bar = new FooFizzBuzzProvider(); But in other instances it hides the underlying type too much, e.g. var query = (from entity in dbContext.Entities join entity2 in dbContext.Entities2.Include( e => e.Entity3) on entity.entity2Id equals entity2.entity2Id select new { e1 = entity, e2 = entity2.Entity3 }); It works. It's nice. But sometimes it's too nice. At some point the returned type needs serialized, or some other issue which requires a strong type. You end up rewriting the dynamic stuff with strong types anyway.
