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...

How To Find Out Which NuGet Packages Depend on Yours
Feb 1124Renaming a package ID is a potentially destructive action and one we don’t recommend doing. Why? Well if any other packages depend on your package, you’ve effectively broken them if you change your package ID. For example, today I wanted to rename a poorly named package, MicrosoftWebMvc, to Mvc2Futures. What I ended up doing is recreating the same package with the new ID and uploading it. That way existing packages that depend on MicrosoftWebMvc aren’t broken. But now, I have two packages ...

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...

ASP.NET MVC 3 Extensionless URLs on IIS 6
Dec 1022A lot has been written about how to get ASP.NET MVC running on IIS 6 with extensionless URLs. Up until now, the story hasn’t been very pretty. When running ASP.NET MVC on ASP.NET 4, it gets a lot easier. To be fair, the part that makes it easier has nothing to do with ASP.NET MVC 3 and everything to do with a little known new feature of ASP.NET 4 creatively called the ASP.NET 4 Extensionless URL feature. ASP.NET MVC 3 requires ASP.NET 4 so it naturally benefits from this new feature. If yo...

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...

Using RavenDB with ASP.NET MVC
Nov 1008Traditionally when you think about a database you think of tables, views, indexes and stored procedures. If you have made a career out of developing database centric applications like I have, then chances are that you have spent a great deal of time dealing with issues around referential integrity, normalization and performance. Unless you have been living underneath a rock, then you have probably heard of the newest database trend named NoSQL. NoSQL refers to non relational document databas...

A Sordid Little Tale Of Unexpected Security Exceptions
Nov 1005It was a dark and stormy coding session; the rain fell in torrents as my eyes were locked to two LCD screens in a furious display of coding … …sorry sorry, I just can’t continue. It’s all a lie. This actually a cautionary tale describing one subtle way that you can run afoul Code Access Security (CAS) when attempting to run an application in partial trust. But who wants to read about that? Right? Right? Well this isn’t a sordid tale, but if you bear with me, you may just find it intere...

MvcSiteMapProvider 2.2.0 released
Oct 1027Im proud to announce that MvcSiteMapProvider 2.2.0 has just been uploaded to CodePlex. It should also be available through NuPack in the coming hours.

Targeted at ASP.NET MVC 2, it provides sitemap XML functionality and interoperability with the classic ASP.NET sitemap controls, li...

Hosting Your Own Local and Remote NuPack Feeds
Oct 1021Note: Everything I write here is based on a very early pre-release version of NuPack and is subject to change. A few weeks ago I wrote a blog post introducing the first preview, CTP 1, of NuPack Package Manager. It’s an open source (we welcome contributions!) developer focused package manager meant to make it easy to discover and make use of third party dependencies as well as keep them up to date. As of CTP 1, NuPack by default queries an online ATOM feed temporarily located at http://go....
