.Net open source tools and components

[ntg]

I've been discussing about a specific .Net open source project in another thread and it occurred to me to start a new thread here. I'm hoping to get input about .Net open source projects that people have actually used in their own applications and production projects.

Here goes my own list.

• Log4Net is by far the handiest logging component I've encountered. I've been using this since 2004 and I'm extremely happy with it.
• Sandcastle Help File Builder proved a life-saver in assisting with help file generation.
• I've deployed DotNetNuke in a couple of situations where I didn't want to just write another ASP.Net application. Easy to install, configure and extend.
• iTextSharp has been a great component for creating PDF files. Difficult to work with initially, but with a lot of options.
• I've used sharpSVN to integrate a solution with an SVN repository.
• ZedGraph comes pretty handy when you need to create and show graphs.
• #ziplib is a great component to help you work with reading and writing compressed files.
• I've recently used FileHelpers to quickly implement code that reads/writes files in a proprietary format.
• 32.feet is indispensable when you're writing mobile applications that need to connect using blue tooth.
• Smart Thread Pool provides a great implementation of a thread pool.
