There are some third party SDK's which give support for the .Net Core. One of them is ByteScout. You can use their SDK and can generate PDF in .Net core. You can find the sample code under this link.

Furthermore you can convert your docx to pdf, please follow the code given under this link

https://bytescout.com/articles/pdf-sdk-c-convert-docx-to-pdf
using (DocxToPdfConverter converter = new DocxToPdfConverter())
            {
                converter.PageSize = PaperKind.A4;
                converter.Orientation = PaperOrientation.Portrait;
                converter.Footer = "FOOTER TEXT
";

                converter.ConvertDocxToPdf("sample.docx", "result.pdf");
            }

            // Open result document in default associated application (for demo purpose)
            ProcessStartInfo processStartInfo = new ProcessStartInfo("result.pdf");
            processStartInfo.UseShellExecute = true;
            Process.Start(processStartInfo);

If you want to do this without using any additional libraries in your project, you can try LEADTOOLS Cloud Services that support conversion to different document formats through native .NET classes, JavaScript (Node.js) and others.

The following code shows how you can submit a conversion request using C#:
public async Task ConvertFile()
{
var client = InitClient();
int firstPage = 1;
int lastPage = -1;
// set the Target format to PDF
int fileFormat = 4;

//If uploading a file as multi-part content:
HttpContent byteContent = new ByteArrayContent(File.ReadAllBytes(@"path/to/file"));
byteContent.Headers.ContentDisposition = new ContentDispositionHeaderValue("form-data")
{
   Name = "attachment",
   FileName = "file-name"
};
var formData = new MultipartFormDataContent();
formData.Add(byteContent, "formFieldName");

string conversionUrl = string.Format("Conversion/Convert?firstPage={0}&lastPage={1}&format={2}", firstPage, lastPage, fileFormat);
var result = await client.PostAsync(conversionUrl, formData);
formData.Dispose();

// If using URL to the file
/* string fileURL = "https://AddressOfSite/source.doc";
string conversionUrl = string.Format("Conversion/Convert?firstPage={0}&lastPage={1}&fileurl={2}&format={3}", firstPage, lastPage, fileURL, fileFormat);
var result = await client.PostAsync(conversionUrl, null); */

if (result.StatusCode == HttpStatusCode.OK)
{
   //Unique ID returned by the services
   string id = await result.Content.ReadAsStringAsync();
   Console.WriteLine("Unique ID returned by the services: " + id);
   await Query(id, client);
}
else
   Console.WriteLine("Request failed with the following response: " + result.StatusCode);
}

It doesn't looks straight forward i.e. you may need HTML in between. If format is ".docx", OpenXML can be used in .NET framework, not in .NET Core though. Please read this https://stackoverflow.com/questions/46580718/convert-word-doc-and-docx-format-to-pdf-in-net-core-without-microsoft-office-in
