Question

I’m currently using F# and XNA for my new project, but got stuck when implementing XNA’s IUpdateable interface. Specifically when I need to implement the event handlers.

This is what I have:

let enabledChanged = new DelegateEvent<System.EventHandler>()

and further down:

interface IUpdateable with
    ... // other stuff
    [<CLIEvent>]
    member self.EnabledChanged = enabledChanged.Publish

But i’m getting this error:

Error 2 This expression was expected to have type EventHandler but here has type EventHandler<EventArgs>

I’ve tried several things but can’t get this to work. What is expected to be there?

Thanks in advance!

Answer 1

Have you tried defining enabledChanged in the following way?

let enabledChanged = new Event<_>()
