I passed Exam 70-528 TS: Microsoft® .NET Framework 2.0 - Web-Based Client Development today! I dare say I'm Microsoft's newest MCP. =]
Some of the topics on the exam included:
DataSets
- DataTable Columns
- Data Row Properties
Reading Xml Files
Mobile Forms
Mobile Master Pages
Webparts
Custom Controls
- Composite Controls
- Template Controls
Sitemaps
TreeView
Authorization
- Web.config
Authentication
- Windows
Command Line Utilities
Overall it was a pretty tough test. Much harder than the practice tests I took. I didn't study a whole lot, and didn't use a book specifically geared for the exam, so your mileage may vary.
