iron-pdf-example-hello-world-csharp's Issues

Page break issue

I am applying page break styles to table but these are not applying in creating pdf.

After upgrade to V 2020.8.1 and 9.0 the deployment (Azure web app) will taking more than 25 min

After upgrade IronPDF version 2020.8.1 or 2020.9.0, the Azure web app ( ASP.NET MVC 5) deployment takes more than 25 minutes and sometimes failed.

For confirming this, we downgraded the IronPDF version to 2020.6.0 and deployed the same to the Azure web app and it will only be taken 1 min and 45 sec.

After publishing the web app with IronPDF version 2020.8.1 or 2020.9.0, the Azure portal showing extremely high CPU usage (100%) within the Azure App Service.

After downgrade to 2020.6.0, The CPU usage has stabilized at around 10-30% in Azure App Service.

Please advice.

Unity-Version 2018.3.14f crashes when using the net40 version of iron pdf

Hello IronPDF-Crew,

I want to use the IronPDF Plugin in Unity, specifically in a UWP build, but using the following code Unity just crashes.

        HtmlToPdf Renderer = new IronPdf.HtmlToPdf();
        PdfDocument PDF = Renderer.RenderHtmlAsPdf("<h1>Hello IronPdf</h1>");
        string OutputPath = "HtmlToPDF.pdf";
        PDF.SaveAs(Path.Combine(Application.persistentDataPath, OutputPath));

Is there a known solution on this?

Embedded Browser

This is not of an issue but a question: I read somewhere that IronPDF has an embedded browser in it. Can I show that browser in my WPF application?
