IronBarcode NuGet Fails on Visual Studio 2015
Installing IronBarcode into a VB.NET project on .NET Framework 4.5 to 4.8 under Visual Studio 2015 can fail: the NuGet package either refuses to install or does not load once added.
The likely culprit is netstandard2.0. IronBarcode ships targeting that format, and Visual Studio 2015 does not fully support it. The same package installs cleanly on Visual Studio 2022, so the outdated IDE is the most probable cause, though this was not confirmed by direct reproduction.
Solution
1. Upgrade to Visual Studio 2022
Move off Visual Studio 2015. Older IDEs do not fully support the netstandard2.0 package format IronBarcode ships, which is the root of the install and load failures.
2. Use the Latest IronBarcode Release
Update to IronBarcode 2026.4.2 or newer. Recent versions install and read barcodes correctly on current tooling.
3. Install the .NET Framework 4.8 Developer Pack
On the build machine, install both the .NET Framework 4.8 Developer Pack and the .NET Framework 4.8 runtime.
4. Prefer PackageReference Over packages.config
Where possible, migrate the project's NuGet references to PackageReference. It handles transitive dependencies and modern package formats more reliably than the legacy packages.config.
