Actually I am trying to convert html content to pdf using NReco PDF converter, however, this line of code pdfDoc.GeneratePdf(HtmlContent); unable to get through on Azure web app, but it works normally on my dev environment. So my Question is which cloud service should i go for?
Azure Apps (former WebSites) operate in restricted (partial-trust) environment and wkhtmltopdf.exe (that is internally used by NReco PdfGenerator wrapper) cannot be executed in this case directly from asp.net application.
update:
Unfortunately it will not work with Azure WebJobs as well: tasks are executed under the same (limited) environment as WebSites and GDI functions used by wkhtmltopdf are disabled.
If your ASP.NET app uses wkhtmltopdf-based component for PDF generation (doesn't matter how it is invoked - in separate process or as native DLL API) it will work only under Azure WebRole / WorkerRole / VM.
-- update 2017 --
Wkhtmltopdf (and NReco PdfGenerator wrapper) can be used with Azure Apps with VM-based subscription plan (Basic or higher). At least one issue still exists: it seems fonts API is still restricted and custom fonts cannot be rendered to PDF.
