opened on Nov 20, 2025
  • Version: 0.2
  • Target: .net 10.0, electron 38.2.2 node v22.12.0

Steps to Reproduce:

  1. Try to use await Electron.Screen.GetPrimaryDisplayAsync();
  2. Error:System.TimeoutException: No response after 1000ms trying to retrieve value screen.GetPrimaryDisplayAsync()

The Screen id is set to -1 so that's probably not correct.

    I'm not sure how you got to those results.

    The GetPrimaryDisplayAsync() method is tested by the Primary_display_has_positive_dimensions test which is succeeding on all platforms (e.g. https://github.com/ElectronNET/Electron.NET/actions/runs/19494438431)

    I have no idea either :-) All I did was migrate from electron-sharp to ElectronNet Core.
    I did test on MacOS 26.1 and 15.4.

    I also tested the bare bones demo app. Doesn't work on that one either.

    Is there anything you can recommend that I do to prove that it's not working for me?

    Is it like that's the one thing not working and everything else is fine, or is this the first thing your app does and you didn't look any further?

    Is there anything you can recommend that I do to prove that it's not working for me?

    A minimal app which exposes that problem would be helpful to look at what you are doing. (unless your code is open anyway.. :-)

    That was the only thing that I noticed wasn't working. Everything else has been fine. Code isn't open but the minimal app i can post

    You could check out the develop branch and run dotnet test on that machine, so that we have a baseline (known to be working) for comparison.

    That includes the test for the screen.API.

    This is not the default app startup. How do you do this?

    Did you look at the example AspNet app?

    Most likely you're just doing this too early?

    https://github.com/markatosi?tab=repositories BlazorApp1

    The call to the method is via the counter button on the counter.razor

    I just followed the Blazor setup that is on the home page for this project with the exception of the WASM stuff since this is a blazor server app.

    Here's the output after enabling the logger

    Thanks - but no longer needed. The error is on our side.

    I think it's due to the migration to System.Text.Json: The Json.NET serializers have probably ignored the type mismatch for DisplayFrequency while System.Text.Json does not.

    I doubt they "ignored" the type mismatch. Newtonsoft just gracefully handled it and no one was the wiser. i still need to use JSON.net in places because it just "works" for some things that seem impossible for system.text.json to do without a lot of hair pulling.

    Also, i wouldn't take much stock in github integration tests "passing" at least with respect to macos. I've had plenty of issues with nonsense there. There might be something different about how system.text.json works on .net for mac. Might be worth creating an issue with the dotnet team because it shouldn't work on windows and fail on a mac.

    Anyway, I'm happy to run integration testing on my mac whenever you need me to if you want a real test done. Just let me know

    I'm quite satisfied with it so far.

    I thought it would be obvious, but in case you're wondering why it didn't fail: Because Displayfrequency values are integers there.. 😜

    What would be the difference between "ignored" and "gracefully handled"?

    I guess converting the floating point or decimal or whatever it is to an integer. Maybe it's an 80/20 type solution :-)
    We'll give you a mostly correct answer which is probably good enough most of the time.

    Anyway, thanks for all your improvements to ElectronNet. The fact that i can debug the application without having to attach to the asp.net core process separately is awesome.

    Hmm, that would be a crazily invalid behavior. But I don't know they're really doing.

    Other note: A quick fix for you - until it's fixed here - might be to change your monitor refresh rate to an integral value - LOL 🤣

    In some monitor reviews on YouTube I have seen multiple instances of monitors reporting decimal refresh value on Windows as well.
