This is only a spike on my part so don’t expect too much, but the code shows…More

Fake Fibers using Async CTP
This is another PoC, building recursive code with continuations using the Async CTP. The code creates a fake fiber, which can be suspended and resumed, thus allowing us to “step” through its actions. This technique could be useful when building an interpreting language where you might want to step through the expressions.More
F# style Mailbox / Agent using C# async CTP

The message loop is executed on the threadpool for each iteration and then suspended…More
