Did you add the property "copy if newer" of the wkhtmlpdf.exe in csproj?

Like this:

  <ItemGroup>
    <None Update="Rotativa\Linux\wkhtmltopdf">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </None>
    <None Update="Rotativa\Mac\wkhtmltopdf">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </None>
    <None Update="Rotativa\Windows\wkhtmltopdf.exe">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </None>
  </ItemGroup>
