Checking if an Unloaded Collection Contains Elements with NHibernate
If you want to know if an unloaded collection in an entity contains elements, or count them, without actually loading them, you need to use a custom query; that is because the Count property (if the collection is not mapped with lazy=”extra”) and the LINQ Count() and Any() methods force the whole collection to be loaded.

NHibernate Tools: Visual NHibernate
You probably know that I’m a big fan of Slyce Software’s Visual NHibernate. To me, it is the best tool for generating your entities and mappings from an existing database (it also allows you to go the other way, but I honestly have never used it that way).

Adding Custom SQL Functions to NHibernate at Runtime
The classic way to register custom SQL functions on NHibernate consists in subclassing a specific Dialect (for example, MsSql2008Dialect) and making a call to the protected method RegisterFunction somewhere in the constructor. Of course, if you use multiple dialects, you have to subclass them all.

Adding Modules Dynamically to ASP.NET
As you may already know, ASP.NET 4.0 brought along with it a new mechanism to execute methods before the application start event (the Application_Start method): the PreApplicationStartMethodAttribute. This attribute, when applied to an assembly, indicates a method which is to be run before the application starts. If your web application references any assembly which has this attribute, it will run the method it declares, throwing an exception it if is not found.

NHibernate Interceptor for Dynamic Proxy Generation
NHibernate comes along with a nice code generation API that is used, for example, for lazy-loading proxy generation. It can, however, be used for other purposes, such as adding interfaces to the loaded entities, for example, INotifyPropertyChanged coming to my mind. Ayende and José have talked about this in the past, but I decided to publish my own updated version.

New Location for .NET 4 GAC
.NET 4 newcomers may have realised that the old GAC location (%WINDIR%\Assembly) does not contain .NET 4 global assembly cache assemblies. Indeed, they have moved to %WINDIR%\Microsoft.NET\Assembly. It is worth noting that this folder does not use the shell extension that the older one uses, which prevents us from directly looking at the folder's contents, which, IMO, is nice (I mean, the new behavior). The old folder continues to host pre-.NET 4 assemblies.

Local Entities with NHibernate
You may know that Entity Framework Code First has a nice property called Local which lets you iterate through all the entities loaded by the current context (first level cache). This comes handy at times, so I decided to check if it would be difficult to have it on NHibernate. It turned out it is not, so here it is! Another nice addition to an NHibernate toolbox!

Generating PDF Files With iTextSharp
I recently had the need to generate a PDF file containing a table where some of the cells included images. Of course, I used iTextSharp to do it. Because it has some obscure parts, I decided to publish a simplified version of the code I used.
