CachingCallHandler and Unity 2.0
Unity 2.0 no longer includes CachingCallHandler, as you can see in here. Since this is something I use very often, I decided to bring it back, with some changes:

Exposing a Class as a COM+ WCF Service
Remember COM+? Well, it is still around, and, in the days of WCF, it still usefull in certain scenarios, mostly because of the services COM+ offers OOTB (transactions, synchronization, object pooling, etc). For those of you that don't know how, I'm gonna demonstrate how you can expose an ordinary .NET class into both a COM+ component and a regular WCF service. Make sure you have Windows SDK 6.x or greater installed.

Detaching an Entity in LINQ to SQL
LINQ to SQL, shamelesly, does not have a Detach method, like most other O/RMs. In one particular case, I needed one - or, at least, I thought I did - so I went to write one, which wouldn't require me to use a base class. Thanks to Reflector, here's what I came up with (only tested it in version 1, not 4):

Two Clicks Required
Sometimes, when I have an UpdatePanel and multiple validators on a page, I have to click twice on a LinkButton, even if it has CausesValidation set to false. The control is outside the UpdatePanel, so I'm not sure what causes this. It is a frequent problem, as can be seen on Google.

Unit Testing Asp.NET Applications with with Moles and Pex
It has been a while since my last post. I will try to recover, there are some things I would like to talk about. For now, check out this fine tutorial for unit testing ASP.NET applications using Pex and Moles: http://research.microsoft.com/en-us/projects/pex/molesaspnet.pdf.

Dynamic LINQ Methods
Continuing the Dynamic LINQ series, here are some hopefuly useful methods for performing LINQ queries in IQueryable or IQueryable<T> object, with String parameters. The available methods, so far, are:
-
Displaying Empty GridView
What happens if your GridView control does not have any records to display? Well, if you set the EmptyDataText or EmptyDataTemplate properties, the grid will show something, only probably not what you'd like - the normal structure, as if it was populated with records. Here's a possible solution:

NDepend 3
Patrick Smacchia, of NDepend fame, was kind enough to offer me a license for its latest version, 3.0, now fully integrated with Visual Studio 2010.

Manually Seting a LINQ to SQL Entity's Timestamp
Suppose you want to manually persist your LINQ to SQL entities without an ObjectDataSource or LinqDataSource using the entities' timestamp column. You pick the timestamp, perhaps from an hidden field on your page, but you cannot change the System.Data.Linq.Binary property to another value, because the Binary won't allow it. You need to use reflection, here's how:

NHibernate 2 Beginner's Guide Book
Packt Publishing has recently released a new book on NHibernate: NHibernate 2 Beginner's Guide, by Aaron Cure. I am now reading the final version, which Packt Publishing was kind enough to provide me, and I will soon write about it. I can tell you for now that Fabio Maulo was one of the reviewers, which certainly raises the expectations. In the meanwhile, there's a free chapter you can download, which hopefully will get you interested in it; you can get it from here.

Table and Column Checksums

Change Tracking
You may recall my last post on Change Data Control. This time I am going to talk about other option for tracking changes to tables on SQL Server: Change Tracking.

Visual NHibernate Update
I have previously talked about Visual NHibernate. It has grown since last time, now offering support for multiple databases (SQL Server, Oracle, MySQL, PostgreSQL, Firebird), generates projects from existing databases or from existing Visual Studio projects and produces XML or Fluent mappings, to name just a few. To me it is by far the most interesting tools for working with NHibernate I know of (granted, I haven't tried NHibernate Profiler).

Exam 71-516: Accessing Data with Microsoft .NET Framework 4
I had the chance to take the beta version of exam 71-516 today. Here are my thoughts on it: first, I was rather annoyed to discover that I will only know if I passed or not about 8 weeks after the beta period expires (July, 02), which probably means September. It was a difficult exam, especially since I don't have any practice on some of the new Entity Framework options. The items covered, from the most covered to the least covered, were:

Speeding Up NHibernate Startup Time

Initially Unselected DropDownList
One of the most (IMHO) things with DropDownList is its inability to show an unselected value at load time, which is something that HTML does permit.

ASP.NET Dynamic Data NHibernate Provider
My NHibernateDataSource was just a necessary step in order to build an ASP.NET Dynamic Data provider for NHibernate. I am pleased to say that it is now working! Like the NHibernateDataSource, it is only - for now - merely a proof of concept, it needs cleaning up and still misses the association metadata part, which means no links to associated entities, but list, edit, delete and insert are working fine.

NHibernateDataSource
I wrote a NHibernateDataSource, which can be used in ASP.NET web forms applications just like their counterparts EntityDataSource and LinqDataSource.
