General Always use the Camel Case convention (example: CamelCaseConventionExample)
Thank you for your answer Jornt, but I can't find the answer in the wiki. Please advice?
One of the naming conventions is CamelCase? Does anyone know why it is a best practice to use CamelCase? One reason I can think of is that in complex systems, when you create business rules you need to know exactly what variable you use. Are there other reasons? Will CamelCase be a best practice in future model driven tools?
