LINQ to SQL is fascinating - the more I work with it, the more I hate it, and then love it again all at the same time. Recently we had an issue while using it in a slightly older version of our N-Tier WCF application which uses LINQ to SQL as it's primary ORM solution (yes, I know). I'll try to briefly...

We decided to use FilteredViews instead of FetchXml for an internal project, but we ran into couple of problems. You can't access data from the FilteredViews using ASP.NET since it runs under NETWORK SERVICE (by default (app pool)), FilteredViews filter the data by Users. If you set the <identity>...

The piece has good information about techniques using .NET 3.5 including LINQ to XML (including XDocument) and something in System.ServiceModel.Syndication...

Building functions instead of expression trees. The functional programming features of the latest versions of C# allow developers to harness a very expressive programming paradigm to solve challenges in new, elegant ways. Two of the very interesting new features are the “Func<>” delegate and the...

Yesterday I posted an entry describing a method for building functions as opposed to building expressions to get a more succinct syntax, and in general a more functional approach.
