Can we use PuppeteerSharp with Razor View. I want to send the HTML from Razor View inside AspNetCore app and get the output as PDF. Any references or code samples would be helpful

You can inject the HTML using SetContentAsync and then call PdfAsync

await new BrowserFetcher().DownloadAsync(BrowserFetcher.DefaultRevision);
using (var browser = await Puppeteer.LaunchAsync(new LaunchOptions
{
    Headless = false,
}))
using (var page = await browser.NewPageAsync())
{
    await page.SetContentAsync("Hello World");
    await page.PdfAsync("test.pdf");
}

Thanks..If the page has reference to external JS or CSS files how can I load them or tell Puppeteer to load them. – code_blue Apr 05 '19 at 12:34
Yes, but you have to be sure that a browser can access that resource. It can't be a relative url. – hardkoded Apr 05 '19 at 13:03

According to github you can generate PDF file like this

await new BrowserFetcher().DownloadAsync(BrowserFetcher.DefaultRevision);
var browser = await Puppeteer.LaunchAsync(new LaunchOptions
{
    Headless = false
});
var page = await browser.NewPageAsync();
await page.GoToAsync("http://localhost/your/page");
Stream pdfStream = await page.PdfStreamAsync();
