User Experience Changes in .NET Framework 3.5
In the .NET Framework 3.5 release, there have been a few minor
changes in the user experience based on usability feedback.
The changes focus on three main areas:
Simplify use of Personal Cards
Simplify import of Managed Cards
Give the Managed Card provider more ways to communicate
information to the user
Is It Safe to Roam Cards to an Untrusted Computer?
Moving cards around is simple, but is it okay to put them on the computer at the
library or an Internet cafe? Such computers are untrusted because you don??™t
know what malicious code might be running on them. Because the ?¬?le is decrypted
by code running on the computer, and the secret cryptographic information
is copied to the computer??™s local STS, malicious code might be able to
steal cryptographic key material for Personal Cards. In addition, it would be
easy to forget to delete your cards from the computer, so the next person who
comes along can access your cards. However, the future looks bright for card
roaming. Microsoft has publicly stated that it is looking at improving the roaming
story, which could include putting STSs on mobile devices and making
Information Cards anywhere much easier and much safer to use.
