Two bugs in ASP.NET MVC 3 and a workaround for both
Jun 1114So I spent an hour today arsing about with a couple of ASP.NET MVC 3 bugs. One was a Routing issue that caused it to act differently to MVC 2. The second I found was a FormsAuthentication issue that insisting on sending me to /Account/Login. Amazing how this crept in really given that it was community tested to death with such a massive ASP.NET MVC following so it is a wonder they weren't weeded out and fixed before RTM. Oh well, don't pretend you don't like a challenge. Routing doesn't work t...

Adding MVC dependencies to a project for deployment
Jun 1113Deployment of new web applications has been a bit annoying since the birth of ASP.NET MVC. Production servers with .NET 4 or 3.5 installed will still be missing key assemblies such as System.Web.Mvc.dll. This will cause errors such as "Could not load file or assembly 'System.Web.WebPages.Razor, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies" and "Could not load file or assembly 'System.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf38...

Routing Regression With Two Consecutive Optional Url Parameters
Feb 1120It pains me to say it, but ASP.NET MVC 3 introduces an ugly regression in routing from ASP.NET MVC 2. The good news is that there’s an easy workaround. The bug manifests when you have a route with two consecutive optional URL parameters and you attempt to use the route to generate an URL. The incoming request matching behavior is unchanged and continues to work fine. For example, suppose you have the following route defined: routes.MapRoute("by-day", "archive/{month}/{day}", new { contro...

MvcSiteMapProvider 3.0.0 released
Feb 1104Just a quick note to tell that MvcSiteMapProvider 3.0.0 has been released and is available on CodePlex and NuGet. This version is targeted at ASP.NET MVC 3.

The changelog: Additional UpdatePriority options for generating XML sitemaps Allow to specify target on SiteMapTitleAttribute One action with multiple routes and breadcrumbs Medium Trust optimizatio...

MVC 3 AdditionalMetadata Attribute with ViewBag to Render Dynamic UI
Jan 1131A few months ago I blogged about using Model metadata to render a dynamic UI in MVC 2. The scenario in the post was that we might have a view model where the questions are conditionally displayed and therefore a dynamic UI is needed. To recap the previous post, the solution was to use a custom attribute called [QuestionId] in conjunction with an “ApplicableQuestions” collection to identify whether each question should be displayed. This allowed me to have a view model that looked like this: ...

Class-Level Model Validation with EF Code First and ASP.NET MVC 3
Dec 1010Earlier this week the data team released the CTP5 build of the new Entity Framework Code-First library. In my blog post a few days ago I talked about a few of the improvements introduced with the new CTP5 build. Automatic support for enforcing DataAnnotation validation attributes on models was one of the improvements I discussed. It provides a pretty easy way to enable property-level validation logic within your model layer. You can apply validation attributes like [Required], [Range], a...

A Better ASP.NET MVC Mobile Device Capabilities ViewEngine
Nov 1017In March of 2009 I spoke at Mix 09, Microsoft's Web Conference and presented a number of ASP.NET MVC features. I extended the NerdDinner Sample with a naive implementation of what I called a MobileCapableWebFormViewEngine. Here's the basic implementation. Don't use this, it's broken. public class MobileCapableWebFormViewEngine : WebFormViewEngine{ public override ViewEngineResult FindView(ControllerContext controllerContext, string viewName, string masterName, bool useCache) { ViewEngineRes...
