Some cool design guidelines from Microsoft
Got a few tips for architecture related links from Arvindra Sehmi, a very smart guy and Senior Architect at MSFT EMEA HQ in the UK that I just added to my linkscollection here at dotnetweblogs. Especially I liked this huge doc at MSDN:
Application Architecture for .NET: Designing Applications and Services
He also announces an upcoming paper called "Enterprise Solution Patterns Using Microsoft .NET" that should be worth a look. Additionally I've heard that Microsoft are releasing some kind of Presentation Layer Application Block paper in April.
Exciting times!
