NHibernate: 1.2.0GA Released

NHibernate is a port of Hibernate to the .NET platform. Hibernate is the leading open-source object-relational persistence library for Java, used to persist plain objects in relational databases.


After several years of development, the first stable version of NHibernate, version 1.0, is now available for download. This version is comparable to Hibernate 2.1 in terms of features, with a few small differences.

With the release of version 1.0, NHibernate is also joining the original Hibernate project at JBoss Inc., the company providing support and training services around Hibernate.

Article: LINQ to SQL (Part 6 - Retrieving Data Using Stored Procedures)

LINQ to SQL is a built-in O/RM (object relational mapper) that ships in the .NET Framework 3.5 release, and which enables you to model relational databases using .NET classes. You can use LINQ expressions to query the database with them, as well as update/insert/delete data.

This is the 6th article that Scott Guthrie has written about LINQ. The first 5 can be found below.

Part 1: Introduction to LINQ to SQL
Part 2: Defining our Data Model Classes
Part 3: Querying our Database
Part 4: Updating our Database
Part 5: Binding UI using the ASP:LinqDataSource Control

What is covered in the 6th article?

To SPROC or not to SPROC? That is the question....
The Steps to Map and Call a SPROC using LINQ to SQL
How to Map a SPROC to a LINQ to SQL DataContext
How to Call our Newly Mapped SPROC
Mapping the Return Type of SPROC Methods to Data Model Classes

Podcast: Frans Bouma on LLBLGen

DotNetRocks has published their latest podcast. Carl and Richard talk with Frans Bouma, author of LLBLGen, a very popular ORM modeling and code generation tool for .NET

Frans Bouma started programming in 1986 on a Toshiba MSX-1, at the age of 16. After graduating with a bachelor degree in Computer Science from the 'Hogeschool Enschede' in the Netherlands in 1994, he started working with 4GL systems and post-relational databases, like uniVerse. In 1996 he founded Solutions Design, a company for database driven web-application development. As the lead developer, he developed medium to large enterprise web applications using SqlServer, AS400, COM+, VC++, Visual Basic and Asp. In 2001 Solution Design produced a content management system completely based on Microsoft technologies like SqlServer 2000, COM+, VC++, VB6 and asp. In 2002 Frans developed in C# his first .NET application, the open source LLBLGen code generator for SqlServer stored procedures and .NET classes. Due to the worldwide success of LLBLGen, Frans designed and developed in 2003 for Solutions Design the O/R mapper and code generator LLBLGen Pro, which is currently one of the market-leading data-access solutions for .NET, C# and VB.NET. Frans received for his community efforts the MVP reward for C# in 2004, 2005, 2006 and 2007 and works full time on LLBLGen Pro enhancements. In 2006, HnD, a full featured support system/forum system for ASP.NET 2.0 was released as open source (GPL), written and designed by Frans Bouma.
