C # in a Nutshell, Second Edition

This attribute marks a method as callable only if a compilation variable, given by conditionString , is set. Compilation variables can be set by supplying /define:VARIABLE as a command-line argument to the compiler or by supplying #define VARIABLE directives in the source code itself. If the compilation variable is not set, calls to the marked method are ignored.
