DinkToPdf dll not found libwkhtmltox

Question

I am developing a .net5.0 web api and i am getting the following error while using DinkToPdf:

DllNotFoundException: Unable to load DLL 'libwkhtmltox' or one of its dependencies: The specified module could not be found. (0x8007007E)

I have followed this tutorial, with a few exceptions:

added the service added the service, which was not done in the tutorial

services.AddSingleton(typeof(IConverter),
         new SynchronizedConverter(new PdfTools()));
...
services.AddScoped<IPdfService, PdfService>();

named the services differently, but that shouldn't matter
installed it via NuGet instead of Install-Package DinkToPdf
my project is just an API, frontend is not in C#, shouln't matter sincer the error is here:
```
return this._converter.Convert(htmlToPdfDocument);
```

Did everything else like in the tutorial.

@Aristos is there a way to get it to work without installing the libraries, as they didnt mention them anywhere on the site? — qlabfgerkaSmurf, Mar 26 '21 at 14:20

What is happening there is you are missing the dlls under your project directory.

you can get them here DinkToPdf dlls and include them in your project.

Also, Don't forget to set copyTolocal to 'Copy if newer' in the properties. – Sriyashree Swain Jan 10 '22 at 03:36
The DLLs provided in the link are only for 32 and 64 bit systems. Will they work on Apples arm64 processors? – CodeHat May 10 '22 at 16:29

For me adding this into the csproj file resolved the issue -

<ItemGroup>
  <None Remove="libwkhtmltox.dll" />
</ItemGroup>

<ItemGroup>
  <EmbeddedResource Include="libwkhtmltox.dll">
    <CopyToOutputDirectory>Always</CopyToOutputDirectory>
  </EmbeddedResource>
</ItemGroup>

You can run below and it will install dlls into bin. Make sure copy those dlls into root directory

Install-Package DinkToPdfCopyDependencies -Version 1.0.8
