I’ve recently switched from the Enterprise Library Validation Application Block to using NHibernate Validators. If you are not familiar with the NHibernate Validator project, they are part of the NHibernate Contrib project and offer Validation constraints, and validation runner, and tight integration with NHibernate (especially great if you use NHibernate to generate your DB).

I’ve been playing with Visual Studio 2010 Beta a little and one of my favorite new features (and there are many) is the new web.config transformation feature. 

When using ASP.NET MVC you will eventually want to do a select (drop down) or even a multiple select list, and your first though might be to use <%= Html.DropDownList %>.  Unfortunately you will soon notice that ASP.NET MVC always looks for a match between the name of the dropdown and a property on the model, and if it finds a match, it OVERRIDES the selected value(s) of the select list.  Now of course not being able to reliably set the selected value(s) is a major problem – if you Google this you will get a ton of results and most people solve the issue by just changing the name of the Html.DropDownList(“name”) to something that doesn’t match a model property.

This will be a quick and dirty post about how to get xVal 1.0 (http://xval.codeplex.com/) to work with the new NHibernate Validator 1.2beta (http://nhforge.org/media/p/7.aspx).

I recently setup my first project ever in CodePlex and naturally I am very excited about its tight integration with TFS since my group uses TFS internally for source control as well.  Connecting to CodePlex through the Visual Studio Team Explorer is very easy, you just use one of the tfs0x.codeplex.com servers as your target, and then give them a variation of your username and password to connect.

When working in on a fresh Visual Studio 2008 SP1 install I needed to use TFS (as always) so I installed the TFS Team Explorer client from the TFS disk and I kept getting the following error whenever trying to view/edit Work Items:

In any project where you use an ORM you often have all of your domain classes inherit from a common base class.  Among other things, your base class often contains your identity property.  Mine has a protected IdT (this is the Id type) field called id, and a public getter called ID.

ASP.NET MVC comes with a UrlHelper class in the System.Web.Mvc.Controller.Url namespace, which you can access through the Url property of any controller.  This provides some handy methods to get the url of an action or route, among other things.  For example, Url.Action(“About”, “Home”) will return the string “/Home/About”, which is the relative url of the About action on the Home controller.
