@tobus2012 This has been fixed, please update to Release 5.1.0 or newer.

Note on Xamarin Forms

Xamarin Forms is no longer supported beyond version 5.0.2 of our .NET SDK. Microsoft has guides on migrating to Maui here, if needed.

version 5.1.0 works with xamarin.form? because 5.1.1 does not work

[jkasten2]

@tobus2012 OneSignal stopped supporting Xamarin in the 5.1.0 release. We just update the release notes to make that more clear.

As you noted, Microsoft suggests migrating to .MAUI, as on May 1st 2024 Microsoft won't be making any more updates to Xamarin.

@jkasten2 I get this error when I use version 5.1.0

[jkasten2]

@tobus2012 What platform are you running when you hit this runtime error? Android, iOS, both?

[tobus2012]

Android
I have not tested on iOS, version 5.0.2 works very well on iOS except on some Android devices which returns the errors subject of this ticket
