C# and C++ shared memory

Dealing with shared memory is quite dangerous and error prone - its like multithreaded programming, just a bit more difficult. Whenever possible I always consider using a streamed IPC communication method instead of shared memory (for example sockets). Sockets are my favorite because its so easy to use to interconnect different kind of systems/languages with it (not to mention that its quite easy to run the two processes on separate machines!). Of course depending on your problem to solve sockets may not be a viable option but really consider using simpler IPC than shared memory whenever possible.
