Given an XML description of your entities and relationships, NHibernate automatically generates SQL for loading and storing the objects. Optionally, you can describe your mapping metadata with attributes in your source code. NHibernate supports transparent persistence, your object classes don't have to follow a restrictive programming model. Persistent classes do not need to implement any interface or inherit from a special base class. This makes it possible to design the business logic using plain .NET (CLR) objects and object-oriented idiom. Being a port of Hibernate 2.1, the NHibernate API is very similar to that of Hibernate. All Hibernate knowledge and existing Hibernate documentation is therefore directly applicable to NHibernate. Take a look at the list of Differences between Hibernate and NHibernate for a detailed comparison of Hibernate for Java and .NET or browse the available NHibernate Documentation.

This project plans to implement an API that allows CLR assemblies to be manipulated and instrumented before they are loaded and executed. In the CLR, the AppDomain class and the ResolveEventHandler event handler already provide an excellent mechanism for dynamically loading assemblies into an application domain under the control of the programmer. At the same time, the reflection capabilities of the CLR are extremely powerful. Not only it is possible to query the existing types at runtime, but is also possible to define new assemblies in memory and use Reflection.Emit to generate MSIL on-the-fly. Our plan is to fill the gap between these two concepts. The idea is to have an API that allows the programmer to intercept the class resolution process, examining and manipulating the code that exists in an assembly, before the code is actually defined on the virtual machine. This API will be called RAIL: Runtime Assembly Instrumentation Library. By using RAIL it will be possible to specify specific transformations that must be done at an assembly before it is loaded and executed. These transformations will be specified using a high-level API, abstracting the programmer from the low-level details of MSIL and the assembly binary format. For instance, it will be possible to substitute the references to a class for references to another class, change the name and usage of constants and variables, examine and change existing methods, and so on.
