But how can you obtain a ProgID with dot-notation instead of the ugly plus sign So far, you have used only the basic features of the COM interoperability, but a number of custom attributes can give you finer control over the CCW generation. These attributes are defined in the System.Runtime.InteropServices namespace; and among these classes you ll find the ProgIdAttribute class whose name hints that it is somewhat related to the ProgID. In fact, you can annotate your F# object type using this attribute: open System open System.Runtime.InteropServices [<ProgId("Hwfs.FSComponent")>] type FSCOMComponent = new() as x = {} member x.HelloWorld() = "Hello world from F#!" First unregister the previous component: C:\> regasm hwfs.dll /unregister Microsoft (R) .NET Framework Assembly Registration Utility 2.0.50727.312 Copyright (C) Microsoft Corporation 1998-2004.

given COM interface, it is expected that the COM component returns the pointer to the interface with the appropriate GUID; in this case, the ability to explicitly indicate a GUID is essential to defining a .NET interface that should be marshalled as the intended COM interface. Complex COM components can be tricky to wrap using these tools, and official wrappers are maintained by component developers. Microsoft provides the managed version of the Office components, the managed DirectX library, and the Web Browser control to spare programmers from having to build their own wrappers. In conclusion, it is possible to use COM components from F#, and vice versa. You can expose F# libraries as COM components, which allows you to extend existing systems using F#, or use legacy code in F# programs

The properties we ve decided to make configurable in our RSS reader are indicated within the setOptions method shown here. The slideTransitionDelay property specifies the number of milliseconds an article s slide is visible before transitioning to the next one. The fadeDuration property specifies the amount of time in milliseconds it takes to fade out and subsequently fade in the next slide. Finally, if an error occurs while loading an RSS feed, the errorHTML property specifies the HTML to display as an error message. The defaults for these values, if not explicitly overridden by the user, are shown in this code. It s worth noting here that the component will expect an rssFeeds property of the options object to be passed in as the initial set of feeds to peruse. Because we can t really assume a reasonable default for this value, it s not defaulted within the setOptions method. The intent is that a reader will be created with an options object similar to the example shown here:
