Microsoft LINQ Books

Samuel Jack wrote two interesting posts discussing possible extension methods for LINQ. One is to implement progress reporting of a LINQ query. The other is to implement a way to cancel a running LINQ query. Both implementations are very simple and they are very good to illustrate how LINQ can be extended and manipulated in a simple way by using ...

A comment received by one reader of Programming LINQ suggested me to underline a concept that is not so intuitive using LINQ, especially if you come from years of SQL coding. The idea is very simple. Two entities in LINQ might be related in the model. Whenever this happen, usually it is better to leverage on this existing relationship and not to ...

Finally, the Programming Microsoft LINQ book is available. We updated the website that supports our books (http://programminglinq.com), where you can download the sample code of the book. What’s in this book? Well, we tried to cover everything that was in RTM, but we also introduced technologies that are still in beta or in early CTP stages, like ...

I'm looking into either an ADO or LINQ method that I can use to access some data contained in a VB6 - written program from withing a C# program that I am developing in the ORCAS beta 2 VS. The data is not in a SQL database, not MDB or Access format nor Jet database, and may well a home-grown db. There is an exposed DLL for accessing the ...

I'm happy to know you liked the book!  The May 2006 CTP version of LINQ had several changes in subsequent releases. Our book is based on Beta 1 bits (released in April 2007). Beta 2 differs from Beta 1 in terms of some new features added. While C# had very few changes, VB9 had more new features, mainly becuase they were not ready in ...

LINQ is part of the .NET 3.5 Framework Library. This version of .NET (like the 3.0 version) don't change the CLR runtime, but only adds new assemblies to the .NET 2.0 Framework runtime. The deployment of a .NET 3.5 (or LINQ) program only requires the deployment of a small set of assemblies and, most important, doesn't change existing .NET 2.0 ...

We just updated the corrections document for Introducing Microsoft LINQ book - if you downloaded the document between June 3 and August 20, the only new fix is an error in a listing at page 80. You can download the corrections document here.

Hello again Bennie,I'm very happy to know that you are enjoying the book, please let us know your feeling when you'll finish reading it, we're really interested in your feedback. About your issue, to tell the true the output is correct and the Console.WriteLine written in the book is correct, too. In fact in sample code (downloadable from ...

Hi Bennie,you're right, we'll fix the book and provide an updated ''errata corrige'' downloadable file. Thanks for your support and your apreciation for the book. Bye,Paolo Pialorsi

First of all, I really like the book, I am (slowy) working my way through the bok, and I really enjoy the fact that you show both the IEnumerable<T> extension methods signatures, together with the query syntax. Too many books just focus on the query syntax in my opinion.  in Listing 4-10, the type of the result is ...
