Pro LINQ Object Relational Mapping with C# 2008

Pro LINQ ORM with C# 2008

I must confess that when I read the title of the book “Pro LINQ Object Relational Mapping with C# 2008” I had big pretensions about the book. ORM, as the author mentions in the introduction, is not a subject commonly treated for the .NET world and I was expecting a deep technical book. This has definitively conditioned my final opinion about it.

The book is divided in several parts. You can see below the main ones.

· First one provides you with a fast overview about the ORM concepts. It explains the problematic between database and conceptual models, problems addressed with ORM, laziness, persistence ignorance, etc.

· Second one presents LINQ to SQL and EF explaining the features each one provides.

· Third part does a “complete” implementation of a sample application which provides you some insights about what it does mean working with LINQ to SQL and EF.

The biggest worth of the book is probably the third part, where the author has not limited to write some excerpts of code, instead he has written some requirements and use cases to later on implement them as a developer would do in the “real world”, including even some unitary tests.

What I didn’t like is that, regardless it presents a wide range of concepts none of them is deeply treated, it always remains on the surface, which in my opinion has made of the book a “sugar free” version of what it could be.

Therefore if you are looking for a deep ORM, LINQ to SQL or EF this is not your book. Instead if you have heard noise about these technologies and you are searching for a text to help you with an overview of what is what and the possibilities they offer, Pro LINQ Object Relational Mapping with C# 2008 can be what you need.
