I have an IFormFile that is being posted to a controller and I want to render the image in a pdf I’m generating with PDFSharp.

I made a small function, that reads a PDF, adds some table on original PDF, then saves as a new file.
The problem is when I use it, it seems to block the original file, and several users cannot read it at the same time.

I’m working in a console application targeting .NET v8. I’m using PDFsharp nuget package for PDF file generation. I’m using below code to compress a PDF file of 75 KB. The PDF file mostly contains text.

Using PDFSharp (1.50) I’m trying to open an existing pdf, add some text, then save it again.
