Jon skeet has produced a handy Core .NET refcard for some of those things you might commonly look up in MSDN. It’s 6 pages long and quickly covers:
- Common .NET types, aliases and sizes
- String literals and escape sequences
- Format strings (general, numeric, date/time)
- Working with dates and times
- Text encodings
- Threading
- Using the new features of C# 3.0 / VB 9.0 in .NET 2.0 projects
You have to register which is a bit of a pain (although if you have registered before, you don’t need to register again). There are a few other handy reference cards there too.
