iTextSharp is no longer licensed under the MIT/LGPL license. Versions greater than 4.1.6 are licensed under the Affero GPL, meaning you can't even use it in a SaaS (Software as a Service) scenario without licensing your code under the GPL, or a GPL-compatible license.

Other opensource PDF implementations in native .NET include

Well, free and not-for-free, I use <a href="http://www.websupergoo.com/products.htm" rel="nofollow noreferrer">WebSuperGoo ABCpdf .NET</a> component, that I just love it! 

not-for-free because you need to pay for it.

for free because even if you have to pay, they have a trial version and you can <a href="http://www.websupergoo.com/linktous_legal.aspx" rel="nofollow noreferrer">request a free license</a> if you do not mind that, in your site show "This site uses WebSuperGoo ABCpdf .NET component" with a link to their website.

I did that and I got a free license (version 5 in that time) so, I can say that it works (even if the website is no longer online) - I still have and use the component ~:) 

A wonderful thing that I love with this is that you can do everything that you can thing off with this, create PDF forms and dynamically fill them and send to user by mail or have them to download it, create a pdf from scratch, convert HTML pages into PDF, etc etc etc, please read the documentation, it is a wonderful component.

There is a new project, RazorPDF which can be used from ASP.NET MVC. It is available as nuget package (search for RazorPDF).

IMPORTANT UPDATE as @DenNukem pointed out, it depends on iTextsharp, I forgot to edit answer when I found that out (when I tried to use it), so if your project is not open source and eligible for their AGPL licence, it will probably be too expensive to use.

iText is a PDF (among others) generation library that is also ported (and kept in sync) to C#.

Is there a pdf library attached/that can be attached to .NET 3.5 that allows creation of pdf files at runtime i.e opening a new pdf file, writing to it line by line, embedding images, etc and closing the pdf file all in C# code?

What I want is a set of tools and specifications which allow me to implement a customised pdf writer in C# without using Reporting Services' pdf output option.

是否有一个可以附加到.NET 3.5的pdf库，允许在运行时创建pdf文件，即打开一个新的pdf文件，逐行写入，嵌入图像等，然后用C#代码关闭pdf文件？我想要的是一套工具和规范，允许我在C#中实现自定义的pdf编写器，而无需使用Reporting Services的pdf输出选项。
