F# Equivalent of Destructor

Question

I am translating a C# class that wraps an unmanaged library to F#. I have run into the seemingly simple problem of rewriting the destructor that follows.

class W         


        

Answer 1

Have you tried looking for F# finalizer?

override x.Finalize() = ...

Answer 2

namespace FSharp.Library  

type MyClass() as self = 

    let mutable disposed = false;

    // TODO define your variables including disposable objects

    do // TODO perform initialization code
        ()

    // internal method to cleanup resources
    let cleanup(disposing:bool) = 
        if not disposed then
            disposed <- true

            if disposing then
                // TODO dispose of managed resources
                ()

            // TODO cleanup unmanaged resources
            ()

    // implementation of IDisposable
    interface IDisposable with
        member self.Dispose() =
            cleanup(true)
            GC.SuppressFinalize(self)

    // override of finalizer
    override self.Finalize() = 
        cleanup(false)
