[Public] Can I Use Different Major Versions of IronPDF, IronOCR, and IronBarcode Together?

"Is it possible to use different major versions of IronPDF, IronOCR, and IronBarcode in the same project?"

For example:

• IronPDF v2025.x

• IronOCR v2024.x

• IronBarcode v2023.x

Short Answer: Not Supported

No — using different major versions of IronSoftware products side-by-side in the same project is not supported.

Why Not?

All IronSoftware products are built on a shared internal architecture. That means:

• Shared assemblies and dependencies are version-aligned across products.

• Each product assumes compatibility only with others of the same major version.

• Mixing versions can result in:

  • Assembly binding conflicts

  • Runtime errors

  • Unexpected behavior

Iron Software products are designed to function as a suite of libraries.

Best Practice:
Always use the same monthly version across all IronSoftware products in a project.

For example:

If you're already using different versions and want to align them:

• Upgrade all IronSoftware libraries to the same monthly version via NuGet.

• Confirm changelog and API differences between versions before upgrading.
