Resx file does not produce designer file, application is crashing

[roubachof]

Description

Hello there!

I'm in the process of migration TaskLoaderView to MAUI, it was going alright till I launch the app for the first time.
It crashed right after the Splashscreen.
It was complaining about my resx file (located in Resources\Localization\SampleResources.resx), not being embedded in the resources...
After that I tried a few things, and now it seems even worst: it crashes before the splash, when loading resources assemblies:

[monodroid-assembly] open_from_bundles: failed to load assembly en-US/Retronado.Maui.resources.dll
[monodroid-assembly] open_from_bundles: failed to load assembly en-US/Retronado.Maui.resources.dll
[monodroid-assembly] open_from_bundles: failed to load assembly en/Retronado.Maui.resources.dll
[monodroid-assembly] open_from_bundles: failed to load assembly en/Retronado.Maui.resources.dll
[.retronado.mau] * Assertion: should not be reached at /__w/1/s/src/mono/mono/mini/mini-exceptions.c:456
[libc] Fatal signal 6 (SIGABRT), code -1 (SI_QUEUE) in tid 9031 (.retronado.maui), pid 9031 (.retronado.maui)

I think it is related to the resx file, cause It fails to generate the design file when building the project on Rider EAP AND on VS Mac Preview.

Steps to Reproduce

Here is the repo sample:

https://github.com/roubachof/Sharpnado.TaskLoaderView/tree/failing-resx

• Project is Retronado.Maui
• The resx is Resources\Localization\SampleResources.resx

Version with bug

6.0 (current)
VS for Mac preview 17.3 build 191

Last version that worked well

Unknown/Other

Affected platforms

Android, I was not able test on other platforms

Affected platform versions

Android 21 and up, probably iOS, since resx doesn't generate anything

Did you find any workaround?

nope

Relevant log output

No response

verified with with vs main (32526.500.main)
it works well on Android emulator:

Sorry I forgot to say that the project that is crashing is:

Project is Retronado.Maui
The resx is Resources\Localization\SampleResources.resx

I edited the issue

whoops! my bad. repro on android emulator, the app also crashed on IOS emulator

@roubachof Did you try moving the resx files into a different directory besides under Resources?

Hi @roubachof. We have added the "s/needs-info" label to this issue, which indicates that we have an open question for you before we can take further action. This issue will be closed automatically in 7 days if we do not hear back from you by then - please feel free to re-open it if you come back to this issue after that time.

[roubachof]

@drasticactions yes, at the beginning, the resx was in the Localization directory, directly at the project's root.

[drasticactions]

Have you tried making an android app without MAUI (ex. dotnet new android) and trying the same thing? does it work there?

Maybe it's related to #1855 ?

[roubachof]

@drasticactions the android app launches successfully in this case, with the same resx file.
But like the MAUI single project file, it fails to generate the designer file from the resx file

created a branch for this issue: https://github.com/roubachof/Sharpnado.TaskLoaderView/tree/failing-resx

@jonathanpeppers does this ring any bells?

[jonathanpeppers]

So does the app crash and/or the .resx file doesn't work at runtime on Android?

The Xamarin sample for .resx looks a bit different:

https://github.com/xamarin/xamarin-forms-samples/blob/0a9d148ef06fae1e99b8bf080c0abfbad3df746b/UsingResxLocalization/UsingResxLocalization/UsingResxLocalization/UsingResxLocalization.csproj#L42-L45

We have tests similar to this in xamarin/xamarin-android, that the built-in .resx support works ^^

If the Sharpnado sample uses:

<None Include="Localization\SampleResources.resx">
  <UseVocaDbResManager>true</UseVocaDbResManager>
  <GenerateResource>false</GenerateResource>
  <Generator>ResXFileCodeGenerator</Generator>
</None>
<!-- ... -->
<PackageReference Include="VocaDb.ResXFileCodeGenerator" Version="3.1.1">
  <PrivateAssets>all</PrivateAssets>
  <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
</PackageReference>

Does this VocaDb package just have an issue with MAUI / .NET 6 projects?

@jonathanpeppers :)
you are not looking at the correct branch, this is the master where I'm trying to workaround this issue.
The original branch is here: https://github.com/roubachof/Sharpnado.TaskLoaderView/tree/failing-resx

[jonathanpeppers]

So the error is:

System.Resources.MissingManifestResourceException: Could not find the resource "Sample.Localization.SampleResources.resources" among the resources "Retronado.Maui.Resources.Localization.SampleResources.resources", "Retronado.Maui.App.xaml", "Retronado.Maui.MainPage.xaml", "Retronado.Maui.Platforms.Windows.App.xaml", "Retronado.Maui.Resources.Styles.Colors.xaml", "Retronado.Maui.Resources.Styles.Global.xaml", "Retronado.Maui.Resources.Styles.Icons.xaml", "Retronado.Maui.Resources.Styles.Sizes.xaml", "Retronado.Maui.Resources.Styles.StylesGameView.xaml", "Retronado.Maui.Resources.Styles.Text.xaml", ... embedded in the assembly "Retronado.Maui", nor among the resources in any satellite assemblies for the specified culture. Perhaps the resources were embedded with an incorrect name.

I see the .resources file in here with a different name:

The file in there matches the $(RootNamespace) of this project:

<EmbeddedResource Update="Resources\Localization\SampleResources.resx">

Are you somehow bringing in the source code for this class within this assembly?

I don't really understand how these projects are setup, but it looks like Samples.csproj is expecting the .resources file to be named based on its $(RootNamespace). Your app has the $(RootNamespace) of Retronado.Maui.

We have some tests in .NET 6 for .resx, so it seems like they are generally working:
