Microsoft LINQ Books

To make a long story short: the ADO.NET team is now responsible of ADO.NET Entity Framework (including LINQ to Entities) and of LINQ to SQL (the last one was originally in charge of the a separated team, tied to the C# compiler). There is an evident overlapping between LINQ to SQL and LINQ to Entities and since the first day, Microsoft said that ...

Today I needed to use SqlBulkCopy class passing an IEnumerable<T> as a source instead of a IDataReader. Before writing something that someone else could have already written, I made some search and I found this interesting post that solve exactly this issue. In the post there is also a link to source code. Take also a look at performance ...

Paul Stovell made a presentation on ''Reactive Programming and Bindable LINQ'' at TechED Australia 2008 (unfortunately, I was at the antipode in Italy, but the topic is really interesting). I didn't know there are projects somewhat similar to Bindable LINQ in CodePlex: Obtics and Continuous LINQ. I really like the idea of defining ''live'' queries ...

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.
