Spidey VS PuppeteerSharp

Didn't get a chance to reply earlier but depending on what you're trying to do, you might want a web crawler. I have a crawler on Github that I built for scraping in instances where someone doesn't have an API. If you go this route, I suggest doing it as a background task and go off cached data.

This may be overkill but I have library out there for building web crawlers. Spidey is the library. I'm not suggesting you use it but you could look at it for ideas. It uses a multithreaded, producer/consumer approach that avoids recursion and stack overflow issues. Use a queue, pull from the queue for each url, push new urls on when you find them. Do need to optimize my code a bit more but if it helps at all. But your issue is most likely the fact that you're finding a link to the page you are currently on. HashSet or List of found URLs would solve the issue.

PuppeteerSharp

Otherwise, any pdf to hml chromium based solution hosted via docker, like gotenberg](https://github.com/gotenberg/gotenberg) or browserless.io(which is free if you create open source). Generating pdfs from html directly in .NET was always a pain. Wkhtml (and wrappers that use it) uses WebKit and comes with a load of issues of its own, similar to running and styling anything in Safari. Using chromium based engine saves a lot of time as it's the most popular way of doing it these days. You can also use puppeteer-sharp with local chromium if you host your app on something that allows it(f.e. not Azure Functions).

Puppeteer Sharp is a port of the popular Headless Chrome NodeJS API built by Google. Puppeteer Sharp was written in C# and released in 2017 by Darío Kondratiuk to offer the same functionality to .NET developers.

there is a dotnet package for using headless chrome: https://www.puppeteersharp.com/ its a port of the nodejs package of the same name

For the actual conversion of html to pdf we use PuppeteerSharp (https://www.puppeteersharp.com ) but you need browserless for that, which requires an api key (don’t know the pricing)

The README in the GitHub site has been good enough for me: https://github.com/hardkoded/puppeteer-sharp

Iv'e been using https://github.com/hardkoded/puppeteer-sharp for html to pdf conversion for quite some time with success. (in both .net framework and .net core)

Just generate HTML and use https://github.com/hardkoded/puppeteer-sharp to produce a PDF from headless Chrome.

Another idea is to maybe generate the document as HTML first and then convert the HTML to a PDF (with somehting like PuppeteerSharp. I have found this more flexible in the past, but I have not personally done with with nested tables.
