.NET MAUI8 project does not compile with BarcodeScanner.Mobile Version 8.0.40.1 NuGet package #245

Timonysos · 2024-06-28T06:25:57Z

I added the NuGet package BarcodeScanner.Mobile Version 8.0.40.1 to an empty .NET MAUI8 project and it won't compile.

There are a lot of related issus like #218 and #223.
I tried multiple fixes but it seems like I wasn't quiet able to figure out which packages I need to add.

These are my packages I use:

<ItemGroup>
	<PackageReference Include="BarcodeScanner.Mobile.Maui" Version="8.0.40.1" />
	<PackageReference Include="Microsoft.Maui.Controls" Version="8.0.61" />
	<PackageReference Include="Microsoft.Maui.Controls.Compatibility" Version="8.0.61" />
	<PackageReference Include="Microsoft.Extensions.Logging.Debug" Version="8.0.0" />
</ItemGroup>

I got the following errors:

Hi,
Could you try downgrade the MAUI version to 8.0.41 and try rebuild?
It might be caused by different version using in the library and MAUI. If this is the case, I will try to create a new version to use 8.0.61

I tried downgrading to MAUI version 8.0.40 but still got the same error.

Yes, I tried this set of includes but I didn't work for me.

Hello! We have the same issue after upgrading our app from MAUI 7 to MAUI 8

stepkillah · 2024-07-04T10:16:06Z

including the latest version of Xamarin.AndroidX.Activity worked for me

dalevross · 2024-09-21T04:16:55Z

@stepkillah What version on Xamarin.AndroidX.Activity was that?

15mgm15 · 2024-10-24T04:41:27Z

@dalevross Did you manage to solve this?

alejandro7x · 2024-11-05T13:42:59Z

Any news on this error? We are in the process of migrating an application from Xamarin Forms to MAUI, and we haven't been able to make the switch because this library is a fundamental part of the application.

dotnet add package BarcodeScanner.Mobile.Maui --prerelease -s=https://api.nuget.org/v3/index.json

Hello, I need one that uses newer packages, specifically, I get this conflict:

Xamarin.AndroidX.Fragment.Ktx 1.8.2 -> Xamarin.AndroidX.Lifecycle.LiveData.Core.Ktx (>= 2.8.4)

BarcodeScanner.Mobile.Maui 8.0.40.1 -> Xamarin.AndroidX.Camera.Camera2 1.3.3.2 -> Xamarin.AndroidX.Camera.Core 1.3.3.2 -> Xamarin.AndroidX.Lifecycle.LiveData 2.7.0.3 -> Xamarin.AndroidX.Lifecycle.LiveData.Core.Ktx (>= 2.7.0.3 && < 2.7.1).

I'm also running on maui 8.0.83. Any chance there will be a new release soon ?

dalevross · 2024-11-23T18:23:02Z

I didn't. I managed to get scanning working with the ZXing library
