The evolution of asynchronous controllers in ASP.NET MVC
Jan 1209Asynchronous operations in ASP.NET MVC have always been left a bit behind. They appeared in ASP.NET MVC 2, remained untouched in v3, but now in MVC 4 (especially in combination with C# 5 and async/await) they reached the same easiness of use of the standard synchronous controller. Now (or better, in a few months with the release of ASP.NET MVC 4, .NET 4.5 and C# 5) you can write public async Task<ViewResult> Stuff() { return View(await DoStuff("Some stuff")); } In this post I’m going to...

RFC: Web Platform Installer (WebPI) with an offline feed mode for bandwidth savings
Sep 1124My wife is in the Kingdom of Swaziland this evening. If she was a developer over there and wanted to use Web Platform Installer to get Visual Studio or some large download she would have to patiently bring the bits down over 3G. If she was very well off, she might have ASDL with a maximum speed of 512kbps down, most likely with a cap. I've talked about limited connectivity in African countries and other nations (*cough* New Zealand *cough*) before on this blog and it's no fun. I've told the w...

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...

Mastering ASP.NET MVC 3
May 1109I’m rolling together the outline of Tekpub’s Mastering ASP.NET MVC 3 and I was hoping to drop in a couple of episodes on top of MVC 2, but it’s looking like this release has enough to easily cover 9-10 episodes. So that’s what I’m doing - starting today - rolling together a new series that will be a lot more advanced than MVC 2 - and I think I might redo MVC 2 to cover more basic principles. Thoughts? ...

Modifying the default code generation/scaffolding templates in ASP.NET MVC
Mar 1128One of the things people like the most about my ASP.NE MVC 2 Ninja Black Belt Tips video, besides the Bill Cosby sweater, is the tip where I show how to modify the default CodeTemplates that are used in Code Generation in ASP.NET MVC (either version). Eilon mentioned it on an internal mailing list this week so I thought it'd be worth surfacing again in case you haven't heard of this, Dear Reader. Soon, we'll see even more powerful, flexible, and fun ways to customize your own Scaffolding ...

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. If you are still using ASP.NET MVC 2, no worries: version 2.3.1 contains the exact same functionality but is targeted at ASP.NET MVC 2. 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: ...
