Synchronizes memory access as follows: The processor that executes the current thread cannot reorder instructions in such a way that memory accesses before the call to execute after memory accesses that follow the call to .
Assemblies: mscorlib (in mscorlib.dll)
System.Threading (in System.Threading.dll)
is required only on multiprocessor systems that have weak memory ordering (for example, a system that employs multiple Intel Itanium processors).
For most purposes, the C# lock statement, the Visual Basic SyncLock statement, or the Monitor class provide easier ways to synchronize data.
