    The evolution of asynchronous controllers in ASP.NET MVC

    Asynchronous 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...

  • Two bugs in ASP.NET MVC 3 and a workaround for both

    Two bugs in ASP.NET MVC 3 and a workaround for both

    So 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...

    One 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

    Routing Regression With Two Consecutive Optional Url Parameters

    It 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...

    How was my 2010?

    It’s the beginning of the year again, and exactly as last year, on the 13th of January I’m reviewing the year that passed against the my 2010 resolutions, and see how it went. Who did 2010 go? Before starting the list I want to add a resolutions that I didn’t disclose with my 2010 resolutions: I wanted to move out of Italy in 2010. And since now I’m living in Belgium I think the biggest goal form 2010 was accomplished. But all the other resolutions where a bit shadowed by the big effort need...

    Earlier 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...

    An easy approach to adding user notifications to ASP web applications

    We all have to do it inform the user of some status such as whether their edit saved properly and/or if a form submission was successful. The work here is based on something I picked up on the this blog: http://blog.idleworx.com/2010/11/friendly-css-error-messages-for-java.html. I changed things slightly to take advantage of the .NET environment. Have you ever wanted user notifications that faded out over a certain time interval? Perhaps you want the user to be able to click a message to m...
