I solved this problem more quickly.

Solution: Add these codes inside the Project.Service.csproj

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

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

What you might be experiencing could be a misleading error message, if you don’t have the VSRedist 2015 package installed on the machine/server. (typical for use of c++ libraries)

You could try using my powershell module to detect/silently install the redistributable package: PowershellVsRedistInstaller

You can also just check the powershell code to find where to check in the registry or check where to download the files.
