The Conditional Attribute allows you to create conditional methods.
A conditional method is invoked only when a specific symbol has been defined via #define.
Otherwise, the method is bypassed.
A conditional method offers an alternative to conditional compilation using #if.
Conditional is another name for System.Diagnostics.ConditionalAttribute.
To use the Conditional attribute, you must include the System.Diagnostics namespace.
Conditional methods have a few restrictions.
Conditional methods must return void.
Conditional methods must be members of a class, not an interface.
Conditional methods cannot be preceded with the override keyword.
