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.

After you upgrade your packages, PowerShell uses old versions of the assemblies that were supposed to be upgraded. This is because the assemblies are loaded to PowerShell’s app domain, and as long as they are used from the same app domain, they do not get…
