Orleans.FSharp

Idiomatic F# computation expressions and helpers for Microsoft Orleans grain development.

What it does

Orleans.FSharp replaces verbose C#-style grain implementations with a declarative grain {} computation expression. Define state, message handlers, persistence, timers, reminders, and streaming in a single expression. Concurrency is controlled per message type with interleaveMessage typeof<'Msg>, and FSharpGrain.post gives true fire-and-forget ([OneWay]) calls.

Modules included

Quick example

open Orleans.FSharp

type CounterMsg = Increment | GetCount

let counterGrain = grain {
    defaultState 0
    handle (fun state msg -> task {
        match msg with
        | Increment  -> return state + 1, box ()
        | GetCount   -> return state,     box state
    })
    persist "Default"
}
