Error when trying to build .Net Maui app - getting: Could not load file or assembly 'System.Transactions.Local, Version=7.0.0.0,

Question

Everything works fine when I run Debug, but fails when I try to run Release. My CollectionView was a bit janky when scrolling and I read that might just be a Debug only problem so I wanted to see if it was smooth in a Release build.

So, for one thing - I'm not sure why I'm getting error for android-arm, android-x86, and android x-64 when I have the CPU target as ARM64, but here are the 4 errors I'm getting:

What I've tried:

Setting nullable enable in my Models
Clearing C:\Users\me\AppData\Local\Temp, deleting \bin
Wrapping everything I could think of in a try/catch to catch Null References
Adding <Reference Include="System.Transactions.Local" /> to the csproj
Changing Trimming from CopyUsed to Link (this removes those errors and launches the app, but it immediately crashes and closes with a warning in the Error List:

MSB3073: The command ""C:\Program Files (x86)\Android\android-sdk\platform-tools\adb" -s 19061FDEE001K1 uninstall -k "com.reticentrobot.disc"" exited with code 1.

Running VS 2022 as Admin
Disabling AOT and Trimming (same result as #5)

How are you supposed to debug this kind of thing when it runs fine in debug mode (except the jerkiness on the scrolling)? Any ideas what my issue is or how to fix it? Thanks!!

UPDATE

I got Sentry installed and it is showing that the problem is here during runtime:

public HomePage(IServiceProvider serviceProvider)
{       
    var restService = serviceProvider.GetService<RestService>();
    BindingContext = vm = new PostsViewModel(serviceProvider);
    InitializeComponent();
}

In particular it doesn't like PostsViewModel(serviceProvider):

Microsoft.Maui.Controls.Xaml.XamlParseException: Position 40:9. Can not find the object referenced by `ViewModel`

Anybody out there that can tell what I've done wrong there or should be doing differently to make this run in a Release build?

The issue you mentioned seems related to this issue [MAUI app not working in release mode but it works perfectly in debug mode](https://stackoverflow.com/questions/74566743/maui-app-not-working-in-release-mode-but-it-works-perfectly-in-debug-mode). — Guangyu Bai - MSFT, Aug 18 '23 at 02:23
Wow! Lots of good info in there - thank you for the link! Guess I should have searched for the description of what was happening and not the specific error I was getting, lol. — ReticentRobot, Aug 18 '23 at 13:58
So my crash log was indicating a xaml issue like on the link you supplied so I added `[XamlCompilation(XamlCompilationOptions.Skip)]` like the solutions said to on the file that was indicated as being the issue, but instead of fixing my problem I now just get a different type of crash log without any clues (at least that I see) about what is causing the problem now. I added it to my question in case anyone can help me get pointed toward how to fix it. Thanks!! — ReticentRobot, Aug 18 '23 at 15:05
I think I've narrowed it down to what's causing the problem, if you're available to take a look sometime (added to bottom of question under UPDATE). I appreciate it. — ReticentRobot, Aug 18 '23 at 17:45
I got it working, but it wasn't anything like what I thought was going on... — ReticentRobot, Aug 18 '23 at 18:14

I don't really understand why, but through process of elimination I found out that what was causing the issue wasn't actually this:

public HomePage(IServiceProvider serviceProvider)
{       
    var restService = serviceProvider.GetService<RestService>();
    BindingContext = vm = new PostsViewModel(serviceProvider);
    InitializeComponent();
}

Microsoft.Maui.Controls.Xaml.XamlParseException: Position 40:9. Can not find the object referenced by ViewModel

sort of..., I think it was reporting a XamlParseException because of some code that was surrounding my CollectionView that hadn't been debugged/completed yet regarding a RefreshView:

<RefreshView 
    x:Name="PostsScrollView" 
    IsRefreshing="{Binding ListRefreshing}" 
    Command="{Binding Source={x:Reference Name=ViewModel}, Path=RefreshPosts}"
    RefreshColor="MediumOrchid" >

I'm not sure what the problem with that was exactly, but after removing it the project builds and launches. That said, it still wasn't working perfectly like it was in Debug mode (the CollectionView was loading, but without any pictures or data), and that turned out to be because I was missing a DataType on my DataTemplate:

It's really strange to me how things work perfectly fine in debug mode but not in release like that though!
