Open PDF in Azure

Question

Open PDF in Azure

JORGE MALDONADO BARRERA 211

I have a website in an Azure App Service that generated a pdf. The pdf generates correctly inside a project folder but I also want to open it. I tried the Process.Start("explorer.exe", fileName) which only works when running my project locally and also Process.Start(fileName) which does not open anything. I also tried the following solution without success:

I will appreciate any feedback.

Regards,
Jorge

The file must be downloaded. The the user's browser must have a PDF plugin to display the PDF.

You will have to edit the question to show more on "I also tried the following solution without success", as that's the right approach to go. Similar examples can be found in a lot of other places like https://stackoverflow.com/questions/51614338/asp-net-core-create-and-open-pdf-in-browser . The core idea is that you can never open the PDF file on server side (please forget about that Process.Start) but open the file on browser side.

@JORGE MALDONADO BARRERA ,

You won't have access to processes like explorer inside an app service; see Operating system functionality on Azure App Service and Azure Web App sandbox for more details. Furthermore, from a web perspective, the client has to request to open/download the PDF file you've generated. On your local environment, you're the client which is why it works. To do similarly, when client makes the request to your app which generates your PDF, your app will need to respond with application/pdf HTTP response.
