Assembly: mscorlib (in mscorlib.dll)
A type definition might be marked discardable if it is not referenced by any other code in its assembly. This might be useful for languages that support separate compilation, where it is only at link phase that it becomes known whether any type is actually referenced by other code.
The classes in System.Runtime.CompilerServices are for compiler writers' use only.
The following code example demonstrates how to apply the DiscardableAttribute attribute to a type.
Windows 98, Windows 2000 SP4, Windows Millennium Edition, Windows Server 2003, Windows XP Media Center Edition, Windows XP Professional x64 Edition, Windows XP SP2, Windows XP Starter Edition
