how to raise events from C++ code and call handlers in C# code on another process?

I have been trying to do some reading on how to communicate best, and it appears that the way to communicate between non-related processes running code in different languages is usually through the use of "named pipes."

it seems like in C# you would normally use WCF while setting some bindings to make use of named pipes. However, in C++, should i just directly create a named pipe or is there some framework/library that I should use to create named pipes?

Also, what alternative options do I have to create events in C++ that a C# application can hear?
