NHibernate 3.0 goodness

As the release of Entity Framework 4.0 is getting closer, it's time to have a look at the competition. After the release of NHibernate 2.1(.1), the NHibernate team is working on the next big release based on the .NET 3.5 framework.

A selection of some of the upcoming features in NHibernate 3.0:

  • QueryOver: Allows the usage of ICriteria in a type safe way.
   1:  IList<Student> students =  session.QueryOver<Student>()  
   2:  .Where(s => s.Name == "Fabio")
   3:  .And(s => s.StudentNumber > 100) 
   4:  .List();


  • New Linq provider: A new linq provider is coming up fully based on AST. This will replace the current NHibernate.Linq 1.0 project.
  • Strongly typed configuration for multiple parts of NHibernate(caching, sessionfactory,...)
  • Better WCF integration for session management
  • ...


I think we'll have a very interesting future in ORM land...

A single pod produces about 11 Kg CO2eq per year( here the calculation). Reason enough to give it a try! Installing kube-green in your cluster The easiest way to install the operator in your cluster is through kubectl. We first need to install a cert-manager: kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.14.5/cert-manager.yaml Remark: Wait a minute before you continue as it can take some time before the cert-manager is up & running inside your cluster. Now we can install the kube-green operator: kubectl apply -f https://github.com/kube-green/kube-green/releases/latest/download/kube-green.yaml Now in the namespace where we want t...
