.NET Framework 3.5 Reference Poster
This slick .NET 3.5 reference poster is available as a free download from MSDN. It’s got the most commonly used types and namespaces in the framework. A great quick reference for any .NET developer’s office wall:

As it’s getting progressively harder to keep up with .NET’s continutally expanding scope, this poster is a handy reminder of what’s included. It shows which classes were added in .NET 3.0, and which in .NET 3.5.
There’s a broad cross-section across all areas of the .NET Framework:
- ASP.NET
- WinForms and WPF
- Communications and Workflow
- Data, XML and LINQ
- Fundamentals
Printing
The hi-res version is Microsoft XPS format, so if you’re not using Vista or Office 2007 then you might want the Microsoft XPS Viewer. Also, for ‘easy printing’, there’s a 16 page 4×4 version, but remember: ’some assembly is required if you choose this print method’, so remember to ask an adult for help with the scissors.
My local print shop printed and laminated the PDF version onto A1, which is easily hi-res enough and looks great.
Other .NET Reference Posters
There are a few other reference posters on MSDN, in particular I like the Silverlight Developer Reference, and keyboard shortcuts for Visual Studio 2008, available for both C# and Visual Basic.
