I was at the Security Summit yesterday (based on the DevDays stuff in America), and was reminded yet again of the great Application Blocks that are available, so here's some links:

Microsoft patterns and practices for Application Architecture and Design (the main page)

• Smart Client Offline
• Asynchronous Invocation
• Caching
• Configuration Management
• Data Acces - NOTE: has been updated to version 3, GotDotNet Workspace for DAABAF (supports Abstract Framework)
• Exception Management, there are two:
• Exception Management (basic exception management)
• Enterprise Instrumentation Framework (advanced exception tracking, logging, performance counters etc)
• Logging Application Block (based on the EIF)
• Updater (can auto-download and install updates to your application)

Some of the Application Blocks that aren't as applicable for me, but here for reference:

• Authorization and Profile
• Aggregation
• User Interface Process

Quite a few great bits of code there.

PS: I will be posting an update to my Heirarchial XML into SQL article, as well as it's companion article (SQL->XML), hopefully later this week
