Answer 1

It's not obligatory to add all unless you want to support all platforms.

• so is for Linux
• dll is for Windows
• dylib is for Mac

Next for copying, we have to Load these Unmanaged Libraries to assembly Next copy these to output path , in project settings, add

    <ItemGroup>
  <None Update="wkhtmltox\v0.12.4\32 bit\libwkhtmltox.dll">
     <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
     <CopyToPublishDirectory>PreserveNewest</CopyToPublishDirectory>
  </None>
  <None Update="wkhtmltox\v0.12.4\32 bit\libwkhtmltox.dylib">
