Hello.. I ‘m so sorry that i can’t keep my promise to write article every week, it’s because i was little bit busy on few weeks ago, don’t worry.. i realize about that 😀 . And this time, i’m going to explain about two .Net simple keywords, that maybe some of us don’t care about how to use it. Do you remember the data types fundamental on .Net? Yup, that’s value types and reference types.
