https://fsharpforfunandprofit.com/posts/let-use-do/ example won't compile

[dsysme]

https://fsharpforfunandprofit.com/posts/let-use-do/ The code for testTimerWithDisposable won't compile with newer f# versions. I don't know f# sharp to fix it. This is the error I get: "typecheck error One or more of the overloads of this method has curried arguments. Consider redesigning these members to take arguments in tupled form"
