Introducing concurrency support in F# 4
It is important to have concurrency support from the programming language perspective, especially as built-in language features. In F#, concurrency support in F# was available before F# 4.0. Two of the concurrency features: the asynchronous workflow and MailboxProcessor have been available since F# 1.9.
In a quick overview, F# has the following concurrency features:
Asynchronous workflow
Asynchronous message passing using actor model and an F# special class that functions as an agent for message passing,
MailboxProcessorParallel programming support for asynchronous workflow
Interop with .NET Task Parallel Library (TPL)
Asynchronous workflow is actually an implementation of a computation expression that is escalated as syntactic sugar. It is escalated within a block of asynchronous code that has calls to asynchronous functions, marked in the beginning with async as keyword.
From the perspective of conceptual concurrency, it is quite intuitive and easier...
