Hi, I'm converting our API into a .NET CORE 3.1 Web API and everything seems to be going well. However, when I call EO.Pdf.HtmlToPdf.ConvertHtml(html, path) I get an error and it blows up. I've confirmed that the API has access to the path by creating and saving a file to the same path with a streamwriter. Here is the full error:
Code: C#
System.MissingMethodException: Method not found: 'System.Security.Principal.WindowsImpersonationContext System.Security.Principal.WindowsIdentity.Impersonate(IntPtr)'.

Any help would be greatly appreciated.

Hi,
What version do you use? .NET Core is not supported in our older versions.
Thanks!

Ah! That is probably it! My version is 16.0.28.0
I just downloaded the latest version and am testing it out now. If I still have this issue, I'll respond. Thank you!
