If you want to help your kids understand days of the week better you should have special events that occur on specific days. Like in my house Tuesday is Dairy Queen day: french fries and ice cream.

I think developers often lose sight of the fact that the C# type system is not the .NET type system. Instead the C# type system is merely a layer on top of the .NET type system providing both additional capabilities and additional restrictions.
Think most developers if asked would say C# is a super set of the .NET type system. Providing only new capabilities like lambdas, dynamic, pattern matching, etc ...
