System.DllNotFoundException: wkhtmltox0

[dooburt]

Firstly, great library and with a the two interfaces (single and multi-thread) this seems to be the programmers choice for html > pdf.

That being said however, I am struggling to get this to work on a development machine. I get on run 'Exception has been thrown by the target of an invocation' ... DllNotFoundException, Unable to Load DLL 'wkhtmltox0'. Your documentation says this is automatically created on first conversion - perhaps this isn't happening? Or I need permissions on the bin or something? Can you offer any suggestions?

Thanks :)

Hi dooburt,

There has been some temporal API changes to allow decreasing the final
assembly size, and now the native libraries has been split into it's own
nuget packages (WkHtmlToXSharp.Win32, etc.). You need to add a reference to
the native libraries required by your environmnet (mos probably win32 onyl)
and use WkHtmlToXLibrariesManager.Register(..) to register each native
bundle before using WkHtmlToXSharp for the first time.

I am still not 100% convenced by this API, and I open to suggestions..
Maybe scanning all AppDomain's assemblies or bin folder for native bundles
would be a better idea..

Regards
Pablo

Aha! Thank you.
Do you know in what context the file is written? I get System.UnauthorizedAccessException","Message":"Access to the path 'c:\fakepath\invoice-00029.pdf' is denied.". Do you know which user needs permissions for this? IIS_IUSRS?

(btw, fakepath is used for brevity in this example)

AFAIK if you are running under IIS/Managed ASP.NET, that should be
IIS_IUSR, yes..

Perfect. Thanks a lot. This is working now 👍 :)

I saw you were using NServiceBus and Wk via a third-party service, if you have a blog or description of that setup I'd be very keen to read it.

Once again, great work.
