Description

When attempting to publish the app for iOS using .NET version 8.0.100-rtm.23479.1, the publish fails with:

performance/src/scenarios/mauiiospodcast/dotnet-podcasts/src/Mobile/Controls/Player.xaml.cs(54,9): error CS0103: The name 'podcastImage' does not exist in the current context
performance/src/scenarios/mauiiospodcast/dotnet-podcasts/src/Mobile/Controls/Player.xaml.cs(55,9): error CS0103: The name 'duration' does not exist in the current context

The same issue occured on the CI (https://dev.azure.com/dnceng/internal/_build/results?buildId=2276822&view=logs&j=c04974e3-584c-5152-8f00-7b886e6c86dc&t=1bd054e9-6573-5c14-ef83-f6e1ac550017) with 8.0.100-rc.2 version. These components seems to be defined only when for macOS:

dotnet-podcasts/src/Mobile/Controls/Player.xaml

Lines 45 to 67 in df5d09c

<On Platform="UWP, macOS">
<Grid ColumnDefinitions="auto, *, auto">
<Grid ColumnDefinitions="auto, auto"
RowDefinitions="auto,auto"
Margin="16"
HorizontalOptions="Start"
ColumnSpacing="12">
<Image x:Name="podcastImage"
WidthRequest="56"
HeightRequest="56"
HorizontalOptions="Center"
Grid.RowSpan="2" />
<Label Grid.Column="1"
Text="{Binding Text, Source={x:Reference epiosdeTitle}}"
FontSize="Medium"
TextColor="White"
MaxLines="1" />
<Label Text="{Binding Text, Source={x:Reference authorText}}"
Grid.Row="1"
Grid.Column="1"
FontSize="Small"
TextColor="White" />
</Grid>

However, they are referenced here:

dotnet-podcasts/src/Mobile/Controls/Player.xaml.cs

Lines 45 to 56 in df5d09c

private void UpdatePlayPause()
{
this.IsVisible = true;
this.playButton.Source = this.playerService.IsPlaying ? "player_pause.png" : "player_play.png";
epiosdeTitle.Text = this.playerService.CurrentEpisode.Title;
authorText.Text = $"{this.playerService.CurrentShow?.Author} - {this.playerService.CurrentEpisode?.Published.ToString("MMM, d yyy")}";
podcastImage.Source = this.playerService.CurrentShow?.Image;
duration.Text = this.playerService.CurrentEpisode?.Duration.ToString();
}

Repro steps

  1. Clone the repository and checkout to net8.0 branch
  2. Run the publish command: dotnet publish ./dotnet-podcasts/src/Mobile/Microsoft.NetConf2021.Maui.csproj --runtime ios-arm64 --framework net8.0-ios
