我应该继续将FPDF移植到.NET吗？

I've started to port FPDF to .NET, however I was wondering if its worth the effort.

Has it already been done?

I'm aware of ASP FPDF, but I'm talking about creating a native .NET dll so that any .NET language can use it. I plan to make it public for any one to use.

Further I'm not familiar with PHP, what tips/advice can you give (in terms of porting)?

pdfforge (the makers of PDFCreator) wrote fly2pdf, which is a free (for non-commercial use) ActiveX library for creating PDF files.
