I'm trying to downgrade My C# Winform (Discount Card) from .NET 8.0 to .Net Framework 4.8 in the hope of being able to use the Link-OS SDK. 

I succeeded in downgrading the Data Layer, Business Layer, Presentation Layer like this:

<Project Sdk="Microsoft.NET.Sdk">  
    <PropertyGroup>  
      <OutputType>WinExe</OutputType>  
        <TargetFramework>net48</TargetFramework>  
        <LangVersion>10.0</LangVersion>  
        <ImplicitUsings>enable</ImplicitUsings>  
    </PropertyGroup>  
      <ItemGroup>  
        <Reference Include="System" />  
        <Reference Include="System.Core" />  
        <Reference Include="System.Xml.Linq" />  
        <Reference Include="System.Data.DataSetExtensions" />  
        <Reference Include="Microsoft.CSharp" />  
        <Reference Include="System.Data" />  
        <Reference Include="System.Deployment" />  
        <Reference Include="System.Drawing" />  
        <Reference Include="System.Net.Http" />  
        <Reference Include="System.Windows.Forms" />  
        <Reference Include="System.Xml" />  
      </ItemGroup>  
      <ItemGroup>  
        <Using Include="System.Windows.Forms" />  
      </ItemGroup>  
  </Project>

But failed when downgrading the Service Layer, because I used gRPC to share resources and it is not supported by the .Net Framework!

I want to use the ZC300 Card Printer in My Project, but I am hampered by the Link-OS SDK not supporting .NET 8.0. 

Are there any developers here experiencing the same problem as me, and what is the solution?

Thanks,

Best Regards,

 The Link-OS SDK for .NET 8.0 provides developers with a powerful toolkit for integrating Zebra printers into .NET applications. With features like printing, device discovery, and status monitoring, the SDK simplifies the development process for creating robust printing solutions. It offers comprehensive documentation, sample code, and support, empowering developers to leverage Zebra printer capabilities seamlessly within their .NET projects.    
 

I'm also upgrading my app to .NET 8 and have encountered the same problem. It was running on .NET Framework 4.8 and uses the Zebra.Printer.SDK and Zebra.Printer.Card.SDK nuget packages which all worked fine.

The Zebra.Printer.SDK nuget upgrades to .NET 8 fine since it supports .NET Standard, however the Zebra.Printer.Card.SDK nuget only supports .NET Framework 4.7.1, so it fails to work with .NET 8.

Are there any plans to update the Zebra.Printer.Card.SDK nuget package to support either .NET Standard or .NET 8/Core?

Thanks,
