NHibernate 2.0 went gold yesterday and is available for download from here.
This is official release 2.0.0 GA. Please ensure you review this list of breaking changes from the release notes (also main items briefly listed below).
NOTE: Correction/clarification made 8/26 on Linq to NHibernate location.
The much anticipated Linq to NHibernate is available for now only via the NHibernate Contrib project and is not included in this NHibernate release.
Although likely to change, there does not appear to be an installer for Linq to NHibernate so it must be accessed from the source code. To gain access to this, you will need a subversion client such as Tortoise, and then download the code.
To download ‘Linq to NHibernate’ from the Trunk go here
The location of the bits can be found under the repository at this location:
http://nhcontrib.svn.sourceforge.net/viewvc/nhcontrib/trunk/src/NHibernate.Linq/
NOTE: Pictures Below Generated from NDepend, a must-have tool for .NET Development
gold release 2.0.0.GA
BREAKING CHANGES from NH1.2.1GA to NH2.0.0
-
Infrastructure
- .NET 1.1 is no longer supported
- Nullables.NHibernate is no longer supported (use nullable types of .NET 2.0)
- Contrib moved. New Location
NDepend Analysis
-
Compile time
- NHibernate.Expression namespace was renamed to NHibernate.Criterion
- IInterceptor have additional methods. (IsUnsaved was renamed IsTransient)
- INamingStrategy
- IType
- IEntityPersister
- IVersionType
- IBatcher
- IUserCollectionType
- IEnhancedUserType
- IPropertyAccessor
- ValueTypeType renamed to PrimitiveType
-
Possible Breaking Changes for external frameworks
- Various classes were moved between namespaces
- Various classes have been renamed (to match Hibernate 3.2 names)
- ISession interface have additional methods
- ICacheProvider
- ICriterion
- CriteriaQueryTranslator
Initialization time
- <nhibernate> section, in App.config, is no longer supported and will be ignored. Configuration schema for configuration file and App.config is now identical, and the App.config section name is: <hibernate-configuration>
- <hibernate-configuration> have a different schema and all properties names are cheked
- configuration properties are no longer prefixed by “hibernate.”, if before you would specify “hibernate.dialect”, now you specify just “dialect”
- All named queries will be validated at initialization time, an exception will be thrown if any is not valid (can be disabled if needed)
- Stricter checks for proxying classes (all public methods must be virtual)
Run time
- SaveOrUpdateCopy() returns a new instance of the entity without changing the original
- AutoFlush will not occur outside a transaction – Database transactions are never optional, all communication with the database must occur inside a transaction, whatever you read or write data.
- NHibernate will return long for count(*) queries on SQL Server
- <formula> must contain parenthesis when needed
- These HQL function names may cause conflict in your HQL reserved names are:
- substring
- locate
- trim
- length
- bit_length
- coalesce
- nullif
- abs
- mod
- sqrt
- upper
- lower
- cast
- extract
- concat
- current_timestamp
- sysdate
- second
- minute
- hour
- day
- month
- year
- str
- <any> when meta-type=”class” the persistent type is a string containing the Class.FullName
- In order to set a parameter in a query you must use SetParameter(“paraName”, typeof(YourClass).FullName, NHibernateUtil.ClassMetaType)
Mapping
- <any> : default meta-type is “string” (was “class”)
Stumble It!

Nice NDepend analysis to go with the news… You can see the use of Castle components for example. Too bad Linq will not be ready for a bit.
Now updated with location of Linq to NHibernate.
The reason that NhLinq is not included in the release is that it is not feature complete and there are some major bugs preventing it to be stable.
A new implementation has been started in trunk and hopefully be released with 2.1 if a stability can be achieved.
