How to use <ObservableProperty> in vb.net?

[AndreasReitberger]

I wasn't able to find an vb.net examples, so I tried to write it in vb on my own, however the compiler says here, that
the proeprties are missing for the used Interface.

Basically, I try to rebuild this cs class in vb.net.

https://github.com/AndreasReitberger/SharedMauiCoreLibrary/blob/main/src/SharedMauiCoreLibrary/Models/ViewModelBase.cs

Imports CommunityToolkit.Mvvm.ComponentModel
Imports System.Windows.Threading

Partial Public Class ViewModelBase
    Inherits ObservableObject
    Implements IViewModelBase 

    <ObservableProperty>
    Private Provider As IServiceProvider
    <ObservableProperty>
    Private IsLoading As Boolean = False
    <ObservableProperty>
    Private IsLoadingData As Boolean = False
    <ObservableProperty>
    Private IsLoadingDataCounter As Integer = 0

    Partial Private Sub OnIsLoadingDataCounterChanged(ByVal value As Integer)
        If value < 0 Then isLoadingDataCounter = 0
        isLoadingData = value > 0
    End Sub

    <ObservableProperty>
    Private IsBusy As Boolean = False
    <ObservableProperty>
    Private IsBusyCounter As Integer = 0

    Partial Private Sub OnIsBusyCounterChanged(ByVal value As Integer)
        If value < 0 Then isBusyCounter = 0
        isBusy = value > 0
    End Sub

    <ObservableProperty>
    Private IsReady As Boolean = False
    <ObservableProperty>
    Private IsStartUp As Boolean = True
    <ObservableProperty>
    Private IsStartingUp As Boolean = False
    <ObservableProperty>
    Private IsRefreshing As Boolean = False
    <ObservableProperty>
    Private IsResuming As Boolean = False
    <ObservableProperty>
    Private IsBeta As Boolean = False
    <ObservableProperty>
    Private IsPortrait As Boolean = True

    Public Sub New()
    End Sub

    Public Sub New(ByVal provider As IServiceProvider)
        provider = provider
    End Sub
End Class

Imports System.ComponentModel

Interface IViewModelBase
    Inherits INotifyPropertyChanged

    Property IsBusyCounter As Integer
    Property IsBusy As Boolean
    Property IsLoading As Boolean
    Property IsReady As Boolean
    Property IsStartUp As Boolean
    Property IsRefreshing As Boolean
    Property IsStartingUp As Boolean
    Property IsBeta As Boolean
    Property IsResuming As Boolean
    Property IsPortrait As Boolean
End Interface

This is expected, the source generators are only supported when writing C#.
If you're using VB.NET, you'll have to write observable properties manually 🥲

Ah ok, thanks!
