Use Aspose.Barcode for .Net Standard Library In .Net Framework Projects

Overview

This article describes how to use Aspose.Barcode for .Net .Net Standard libraries with .Net Framework v4.6.2 projects. Aspose.Barcode for .Net uses System.Drawing for any .NET Framework library version and Aspose.Drawing.Common for .Net Standard and .Net Core versions. In this way to use .Net Standard versions of Aspose.Barcode with .Net Framework projects it is needed to add some manual changes to configuration project files.

You can anytime download the example application.

Create .Net Framework project

First, you need to create .Net Framework Console application. You can do this in Visual Studio 2022. For this you need to:

1. Open Visual Studio 2022 and select “Create a new project”.
2. Select Console App(.Net Framework).
3. Set the application name and folder.
4. Select .Net Framework 4.7.2 as target framework.

The second, you need to add the following NuGet packages to packages.config:

• Aspose.BarCode
• Aspose.Drawing.Common
• System.Text.Encoding.CodePages

Update NuGet packages to .Net Standard versions

You can see all of packages are added as .Net Framework versions. We need to change this behavior to .Net Standard versions using with editing two files: packages.config and Aspose.Barcode.NetStandard.csproj.

Edit packages.config

You need to edit packages.config and replace all targetFramework to netstandard2.0 as you can see in the following example:

<?xml version="1.0" encoding="utf-8"?>
<packages>
  <package id="Aspose.BarCode" version="24.1.0" targetFramework="netstandard2.0" />
  <package id="Aspose.Drawing.Common" version="24.2.0" targetFramework="netstandard2.0" />
  <package id="System.Buffers" version="4.5.1" targetFramework="netstandard2.0" />
  <package id="System.Memory" version="4.5.5" targetFramework="netstandard2.0" />
  <package id="System.Numerics.Vectors" version="4.5.0" targetFramework="netstandard2.0" />
  <package id="System.Runtime.CompilerServices.Unsafe" version="6.0.0" targetFramework="netstandard2.0" />
  <package id="System.Text.Encoding.CodePages" version="8.0.0" targetFramework="netstandard2.0" />
</packages>

Edit Aspose.Barcode.NetStandard.csproj

You need to edit Aspose.Barcode.NetStandard.csproj and also replace all paths in Reference HintPath to netstandard2.0 as you can see in the following example:

<ItemGroup>
  <Reference Include="Aspose.BarCode, Version=24.1.0.0, Culture=neutral, PublicKeyToken=716fcc553a201e56, processorArchitecture=MSIL">
    <HintPath>..\packages\Aspose.BarCode.24.1.0\lib\netstandard2.0\Aspose.BarCode.dll</HintPath>
  </Reference>
  <Reference Include="Aspose.Drawing.Common, Version=24.2.0.0, Culture=neutral, PublicKeyToken=716fcc553a201e56, processorArchitecture=MSIL">
    <HintPath>..\packages\Aspose.Drawing.Common.24.2.0\lib\netstandard2.0\Aspose.Drawing.Common.dll</HintPath>
  </Reference>
  <Reference Include="System" />
  <Reference Include="System.Buffers, Version=4.0.3.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51, processorArchitecture=MSIL">
    <HintPath>..\packages\System.Buffers.4.5.1\lib\netstandard2.0\System.Buffers.dll</HintPath>
  </Reference>
  <Reference Include="System.Memory, Version=4.0.1.2, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51, processorArchitecture=MSIL">
    <HintPath>..\packages\System.Memory.4.5.5\lib\netstandard2.0\System.Memory.dll</HintPath>
  </Reference>
  <Reference Include="System.Numerics.Vectors, Version=4.1.4.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a, processorArchitecture=MSIL">
    <HintPath>..\packages\System.Numerics.Vectors.4.5.0\lib\netstandard2.0\System.Numerics.Vectors.dll</HintPath>
  </Reference>
  <Reference Include="System.Runtime.CompilerServices.Unsafe, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a, processorArchitecture=MSIL">
    <HintPath>..\packages\System.Runtime.CompilerServices.Unsafe.6.0.0\lib\netstandard2.0\System.Runtime.CompilerServices.Unsafe.dll</HintPath>
  </Reference>
  <Reference Include="System.Text.Encoding.CodePages, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a, processorArchitecture=MSIL">
    <HintPath>..\packages\System.Text.Encoding.CodePages.8.0.0\lib\netstandard2.0\System.Text.Encoding.CodePages.dll</HintPath>
  </Reference>
</ItemGroup> 

Use Aspose.Barcode for .Net Standard Library

After all upper manipulations you can use .Net Standard version of the Aspose.Barcode for .Net in .Net Framework project. You can see this with the following code:

BarcodeGenerator gen = new BarcodeGenerator(EncodeTypes.Code128, "Aspose.BarCode");
gen.Parameters.Barcode.XDimension.Pixels = 2;
Aspose.Drawing.Bitmap bmp = gen.GenerateBarCodeImage();

using (BarCodeReader reader = new BarCodeReader(bmp, DecodeType.Code128))
{
    foreach (BarCodeResult result in reader.ReadBarCodes())
        Console.WriteLine($"{result.CodeTypeName}:{result.CodeText}");
}
