Can you give me some starting guide line to stat C# and which version of VS I need to use for C#. Also I need a starting guide line of practical OOP user C#. As an example student information system or payroll management type software is fine. I Google on OOP but all this reference I got not satisfy me. Because, I am client oriented programmer. My experience client doesn't bother with OOP or any rich tool he only bother with the output he required. And most of the database software doesn't need too much OOP concept. So it will be helpful for me if you give me some guide line with real database example. Thank you.
