I used LaTeX for writing couple of white papers while I was in grad school. From that I have a really good impression about it in terms of what LaTeX allows user to do, especially the fine control it provides over formatting, etc.
Now I am debating whether I should actually use LaTeX for our production apps to generate PDFs. I have tried several commercial and free PDF libraries (PDFSharp/MigraDoc, iTextSharp, Expert PDF, etc) and none of them provide the amount of fine control I need without making the code base extremely difficult to maintain in long run.
If I do decide to go this route it will be done from C#. Since LaTeX already has command line interface, I should be able to do that pretty easily from C# as an external process forked from my program.
But I was looking for some comments from the community.
All feedback is welcome.
I have previously built a platform for report generation that uses plain TeX (specifically the MiKTeX implementation) to generate reports in PDF format. The platform is used to generate approximately fifty reports per month of varying nature (containing mostly dynamically generated tables and charts). The system is quite flexible. Reports are defined via XML (on an internally-defined report description schema). The platform allows the user to specify a source database table, which fields to extract, the formatting of the fields, a mini query language to filter the appropriate data as well as various formatting elements (page orientation, size, titles, and classifications ("Public", "Internal", "Confidential", etc.).
The main "gotcha" is that it takes a ton of work to end up with a code base that is flexible to change and not a total pain to maintain. A second "gotcha" is that knowledge of TeX (outside of academics) is rare so you could end up becoming the de facto maintainer even if that is not part of your usual role.
