Understanding Cryptography in .NET

I've come across a couple of articles on MSDN that helped me get a perspective on cryptography in .NET.

There is a reasonably full discussion under the "Securing Applications" heading in the .NET Framework Developer's Guide at:

Another one under the Web Services Enhancements topic is a quick overview:
