Comparing DateTimes in a LINQ to SharePoint Query

September 10 2010 7 comments

Last time I blogged about LINQ to SharePoint (available for SharePoint 2010), and especially about the fact that the underlying CAML generation matters, even though it is hidden by the developer. Here is another issue, or a bug, that I came across.

LINQ to SharePoint Performance Pitfalls

September 8 2010 9 comments

SharePoint 2010 introduced LINQ to SharePoint which enables the programmer an easy access to SharePoint lists and content types using LINQ.

After performing several SharePoint 2010 environment installations, this seems also to be the most fragile part of the SharePoint 2010 architecture especially when using a least privileged accounts install model.
