Just I want to make sure If I learn C# 3.0 and 4.0 then I will be able to work on .NET 4.0,4.5,4.6,4.7,4.8 with Organization?
because SO many are saying that the fundamental concepts will remain the same with all .net versions and basic essential does not change from version to version then what is the issue? fundamental concept`s syntax gets old in the new version?
