LINQ (

Introduction Declarative language constructs like query comprehension syntax often worries imperatively trained developers. I hear this quite a bit, and the excuse of “It Just Works” is often not satisfactory for most of them :-). Combine this with interesting...
Introduction Last time around in this blog category we looked at using Z3 for testing satisfiability of simple Boolean logic expressions. Obviously Z3 is capable of doing much more, so this time we’ll reach out to the domain of integer value arithmetic...
Introduction Today I’m going to deviate from the typical path of mainstream technologies I normally cover and enter the domain of research instead. But very interesting and active research, with lots of practical implementations it turns out: theorem...
Introduction On my last trip I had the opportunity to talk on the subject of LINQ once more. Geeky as we are, this time’s session title was “LINQ in breadth”, an orthogonal view on LINQ compared to my last year’s LINQ in depth talk. But what makes LINQ...
Introduction Once more I found myself in LINQ providers land recently for a project yet unannounced. Given the relative poverty of the query language we’re targeting in that particular provider, a very common question came up: what about complex expressions...
Today we’ll take a look at project “MLinq”, a very simple way to perform symbolic matrix calculations based on LINQ expression trees. Introduction But first, why would you even want to do this? Let me tell you I’m a big believer of the power of...
Introduction On last week’s TechEd EMEA Developers 2008 conference in Spain I redelivered my talk on writing custom LINQ providers, showing off implementations of LINQ to AD and LINQ to SharePoint. One of the questions I received afterwards went along...
After named parameters and optional parameters , we'll take a little breadth and deviate a bit from the language specifics to present a new LINQ operator: Zip. Just like a zipper zips two streams of materials together, LINQ's Zip operator can...
Recently I had the opportunity to sync up with Erik Meijer and Charles Torre for a Channel 9 “Going Deep” and “Expert to Expert” interview: Erik Meijer and Bart De Smet: LINQ-to-Anything . In this episode we talk about LINQ’s extensibility mechanisms...
Note for purists: This post only speaks for “LINQ predicates”, not – although closely related to - the mathematic concept of a predicate as defined by Weisstein, Eric W. "Predicate." From MathWorld --A Wolfram Web Resource. http://mathworld...
