[Conditional ( "SILVERLIGHT" )]

Question

WCF Conditional Operations in Service Contract

#if SILVERLIGHT // <------------------------------ ( 1 )
// Silverlight Operations
#else // <------------------------------ ( 2 )
// NON Silverlight Operations
#endif

Mark #1 can be converted to

[Conditional ( "SILVERLIGHT" )]

How to convert Mark #2 ( ELSE Condition [ NON Silverlight ] )

I do not think there is a direct counterpart, and frankly in most cases if you are trying to get one physical file to compile for multiple target platforms, then #if is usually your main option (unless you target the portable class library framework) — Marc Gravell, Aug 12 '12 at 22:33

ConditionalAttribute has some restrictions that #if does not have. Namely, the method cannot return anything but void and you cannot provide a negative version.

#if simply omits the code, but Conditional tells the compiler to noop calls to it.

The ConditionalAttribute is not the same as a C# Preprocessor Directives. So, attempting to replace one with the other is not really appropriate.
