Dependency Injection in ASP.NET MVC3

Fri, 11 Feb 2011 03:48:27 GMT

What dependency injection means is that instead of writing code like this in your controller private IBlogService _BlogService; public BlogController() { _BlogService = new BlogService(); } you write code like this private IBlogService _BlogService; public BlogController(IBlogService blogService) { _BlogService = blogService; } the benefits of dependency injection are your classes are not tightly coupled, are more testable, and really is pluggable. To enable dependency injection into your controllers in ASP.NET MVC2 you had to create a new class derived from DefaultControllerFactory and override the GetControllerInstance method to create the controller using your dependency injection container e.g.

Aspect-Oriented Programming vs Dependency Injection

Fri, 10 Dec 2010 13:41:33 GMT

Aspect-Oriented Programming and Dependency Injection are very different concepts, but there are limited cases where they fit well together. In these situations, using the AOP facility of a DI framework makes perfect sense. For other cases you have two options: abuse from dynamic proxies (a non-solution), or use of a dedicated AOP framework.

Using ModelMetaData in MVC 2 to wire up sweet jQuery awesomeness

Thu, 28 Oct 2010 03:00:52 GMT

I recently came up with an approach to wiring up some jquery plugins that modify the behavior of standard input text boxes. The approach is not original by any means.I got the idea from the built in client side validation for MVC2, which was inspired by Steve Sanderson's xVal framework.

Cool site of the day: extensionmethod.net

Fri, 22 Oct 2010 06:17:33 GMT

I was in a meeting today and the topic of extension methods was discussed. I'm a big fan of LINQ - which at the end of the day - is a collection of extension methods on IEnumerable and IEnumerable<T>. I use LINQ all of the time - but I have to profess - I probably don't utilize extension methods as a way of implementing behaviors as much as I should. Looking around the web tonight, I found this site: http://www.extensionmethod.net/. Looks like a nice clearinghouse for extension methods. Next time, before rolling your own, check out this site. Quite likely, somebody else has solved the problem for you. And - you'll likely pick up some good tips!!

Ten Caching mistakes that break your app

Sat, 09 Oct 2010 03:00:52 GMT

Caching frequently used objects, that are expensive to fetch from the source, makes application perform faster under high load. It helps scale an application under concurrent requests. But some hard to notice mistakes can lead the application to suffer under high load, let alone making it perform better, especially when you are using distributed caching where there's separate cache server or cache application that stores the items. Moreover, code that works fine using in-memory cache can fail when the cache is made out-of-process. Here I will show you some common distributed caching mistakes that will help you make better decision when to cache and when not to cache.

Using delegates to eliminate duplicate code

Thu, 29 Jul 2010 17:43:03 GMT

Here's a simple technique you can use to easily eliminate duplicate code. Try not to let the word "delegates" scare you away from learning the technique and I'll try to refrain from using the word "delegate" as much as possible. I'll start small and then work my way towards a more complex example that really demonstrates its power.

Improving The Code I Write

Wed, 03 Feb 2010 09:34:08 GMT

Something has recently been coming up that has captured my attention: "Code Smells". By Code smells I mean the ability to look or evaluate any piece of code that has been written and assess its value based on a number of indicators. The question that started me on this path is: "How many developers look at ways of improving the way they write code?".

Take Control of Your Web.Config

Tue, 09 Feb 2010 16:30:00 GMT

After reading a Paul Sheriff article in CODE Magazine, I ended up creating a base WebConfig class to handle getting values out of my web.config. I've hated the ConfigurationManager.AppSettings since they deprecated it from ConfigurationSettings.AppSettings. So now I have my own GetAppSetting so I never have to worry about it again. My base class looks like this:
