QUESTION
In the wonderful FBlazorShop repo, Onur Gumus is riffing off of Steve Sanderson’s Pizza Workshop with F# flavor. On line 128 of blob/master/FBlazorShop.Web.BlazorClient/Home/Home.fs [GitHub], Onur is passing an Elmish Message for the parent, HomeView, inheriting ElmishComponent , to a child, PizzaConfigView, inheriting ElmishComponent. By convention, we can see Message being converted (?) to PizzaConfigMsg with this:

QUESTION
I am trying to update ProgressBar.Value in FsXaml. In C#, I used the below-mentioned code. I haven't tried to implement the C# approach in F# as using a public field (myCaller) does not seem to me as being a functional approach (let alone the fact that I do not know if it is at all possible to use this C# approach in F#).

Answered 2022-Jan-15 at 19:18This answer explains how, in Elmish.WPF, progress updates to the user interface can be done from an async.
I have created an example on GitHub that demoes this. The example also demoes another way to call async functions and receive results. And it also demoes how to use mkProgram instead of mkSimple. The demo can be used as a starting template for your Elmish.WPF applications.
This snippet from the demo show the essential code involved in updating a user interface from an async.
Both techniques are based on code from the Elmish Book. You will find a lot of code there that is useful also in Elmish.WPF.
I haven't tried to update a progress bar here, only a status text box, but from this you'll very easily figure out what to do to update anything.

QUESTION
System.InvalidOperationException: 'The calling thread cannot access this object because a different thread owns it.'
I have a WPF GUI with a button that when clicked does:
- starts a control animation (on the GUI), and
- starts a background process to obtain the local printer queues.
I do not want to block the main thread (GUI). However, the code I have gives the above error when I try to update the main thread with the results of the background process.
How do I have a background async process update the main thread without a context violation and not blocking the main thread?

Answered 2021-May-27 at 13:49I haven't looked at your code, but I think the basic answer to your question for WPF is the Dispatcher class. You can also use F#'s Async.SwitchToContext. See this SO question, for example.
QUESTION
What is the best practice is to "register" the http client in one place, so it can be reused from this Elmish update function? Instead of having to create it for every request.
...ANSWER
Answered 2021-Mar-24 at 01:57Probably the best way would either be to add HttpClient as another field in your model or as another parameter to your update function.

I am attempting to mix F# with C#.
In my C# Dependency property, I need the type of e.NewValue -- which is a supplied object from F#/Elmish.WPF
e.NewValue.GetType() returns:
{Name = "ViewModel2" FullName = "Elmish.WPF.ViewModel2[[System.Object, System.Private.CoreLib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e],[System.Object, System.Private.CoreLib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e]]"} System.Type {System.RuntimeType}
which tells me nothing.
How do you get the class/module type of an object from F#/Elmish.WPF
Thank you.

Answered 2020-Oct-25 at 18:01The type is Elmish.WPF.ViewModel<,>. Its access scope is internal, so you don't have access to any stronger type than Object.

...ANSWER
Answered 2020-Sep-24 at 16:59Your code only has three bindings. You should have a binding for every individual piece of data. Specifically, you should change your Rows binding from a OneWay binding to a SubModel binding. Then repeat this for all your other types.
Then, the question you specifically asked about is how to display LastName1 instead of Some(LastName1) and 9/14/2020 instead of Some(09/14/2020 00:00:00). Create the bindings for these individual pieces of optional data with Binding methods that ends in Opt like Binding.oneWayOpt or Binding.twoWayOpt.
