 Compiler warning [CS0114](https://docs.microsoft.com/en-us/dotnet/csharp/misc/cs0114) is issued when breaking [Polymorphism](http://en.wikipedia.org/wiki/Polymorphism_in_object-oriented_programming), one of the most essential object-orientation principles.
 The warning goes away when you add the `new` keyword, but it keeps sub-classes difficult to understand. Consider the following two classes:

 Having properties that cannot be used at the same time typically signals a type that represents two conflicting concepts. Even though those concepts may share some of their behavior and states, they obviously have different rules that do not cooperate.

 Often an event handler is used to handle similar events from multiple senders. The sender argument is then used to get to the source of the event. Always pass a reference to the source (typically `this`) when raising the event. Furthermore don't pass `null` as the event data parameter when raising an event. If there is no event data, pass `EventArgs.Empty` instead of `null`.

 Since LINQ queries use deferred execution, returning `query` will actually return the expression tree representing the above query. Each time the caller evaluates this result using a `foreach` cycle or similar, the entire query is re-executed resulting in new instances of `GoldMember` every time. Consequently, you cannot use the `==` operator to compare multiple `GoldMember` instances. Instead, always explicitly evaluate the result of a LINQ query using `ToList()`, `ToArray()` or similar methods.

 A method that requires more than 7 statements is simply doing too much or has too many responsibilities. It also requires the human mind to analyze the exact statements to understand what the code is doing.

 If you want to use more parameters, use a structure or class to pass multiple arguments, as explained in the [Specification design pattern](http://en.wikipedia.org/wiki/Specification_pattern).
