#if, #else, #endif in C# source code

Question

I\'ve got a sample code from MSDN and I\'ve found code syntax I\'ve never seen before:

namespace Mvc3RemoteVal.Controllers 
{
        public class HomeContro         


        

Answer 1

These are not new features for Framework 4

this are features you can use for development stage and testing: you can declare:

#Define something

and then

#if something

all the code that is in that "if" will be executed. all the code that isn't, won't.
