Invalid assembly version for 'IronInterop' (actual: 2022.x.x.xxxx; expected: 2022.x.x.xxxx). This version of IronPdf requires updated native dependencies. Please clear your build output directory of old assemblies so IronPdf can automatically download the new dependencies at runtime. Alternatively, you may add NuGet package IronPdf.Native.Chrome version 2022.x.xxxx to your project and rebuild.
Seeing this error message, or similar, means that the Native.Chrome package of IronPdf was not automatically updated to the latest version when you updated IronPdf.
This is common in older versions, especially if IronPdf.Slim is the base package used (instead of IronPdf, IronPdf.Linux or IronPdf.MacOs)
To resolve this issue, please either:
- Remove the bin and obj folder, including any temp folders. IronPdf will automatically download the required Native package at runtime
- Remove IronPdf, including bin and obj folders, including any temp folders and then re-install IronPdf
- Add the required Native.Chrome package for your build - IronPdf.Native.Chrome.Windows, IronPdf.Native.Chrome.Linux, IronPdf.Native.Chrome.MacOS
