The main issue with this exception is that the dependency is only tied to IronPdf, not IronPdf.Slim, resulting in IronPdf.Slim being unable to find the correct packages to function correctly. This error only applies to users using IronPdf.Slim v2025.5.6.

Solution

To resolve this, please also install the IronSoftware.Native.PdfModel package. After installing that package, the error will be resolved. This is currently a workaround for IronPdf.Slim v2025.5.x and will be fixed in future versions.
