Interlocked.MemoryBarrier Method
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
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 MemoryBarrier execute after memory accesses that follow the call to MemoryBarrier.
Assembly: mscorlib (in mscorlib.dll)
This method was added to the Interlocked class in the .NET Framework 4.5 as a convenience; it's a wrapper for the Thread.MemoryBarrier method.
MemoryBarrier 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.
