AsyncBuilder.Combine<'T> Method (F#)

  • Article

Creates an asynchronous computation that first runs one computation and then runs another computation, returning the result of the second computation.

Namespace/Module Path: Microsoft.FSharp.Control

Assembly: FSharp.Core (in FSharp.Core.dll)

// Signature:
member this.Combine : Async<unit> * Async<'T> -> Async<'T>

// Usage:
asyncBuilder.Combine (computation1, computation2)

Parameters

  • computation1
    Type: Async<unit>

    The first part of the sequenced computation.

  • computation2
    Type: Async<'T>

    The second part of the sequenced computation.

Return Value

An asynchronous computation that runs both of the computations sequentially.

Remarks

A cancellation check is performed when the computation is executed. The existence of this method permits the use of expression sequencing in the async { ... } computation expression syntax.
