MEF + Factories

2008-11-28T20:13:32Z

Lately I've been really digging into MEF and have been looking at it's pros & cons, ease of use, extensibility, and the simple DI container that it can provide. I'm not going to give an overview of MEF, as others have done so already. What I am here to show off is a concept that may prove useful for some applications. Many of us use a DI container in very simplistic ways, as well as registering injection strategies during type resolution. Read more …

Plea for Help: WCF 404 Error

2008-06-07T02:32:30Z

I’m putting out a plea for help. For some odd reason, we have a WCF service (running in IIS 6) that’s using streaming and BasicHttpBinding that will return a 404 error message every time it’s called from our client. Hitting the same URL on the box itself through IE renders the WSDL just fine. If you have seen this issue, please contact me. We’ve been struggling with this issue and have yet to find a resolution. BTW, it works great on another web server that is configured the same, and we’ve looked at all of the verbose logs WCF can give us. Ultimately, we’re seeing the message being sent from the client, and a 404 in the IIS log, but nothing on the server logging. Thanks!

2008-05-15T05:05:38Z

One nice feature that ASP.NET added in the 2.0 feature set was the ability to embed resources directly within an assembly and then later extract them through a separate Http Handler. You've notably saw this by all the WebResource.axd calls. If you're building a ASP.NET MVC view, you have two ways of extracting web resource urls. Find out how to do this in your view and through a new extension method. (Read More...)

ASP.NET MVC - Living in a Web Forms World

2008-05-13T15:22:51Z

When developing ASP.NET MVC applications, most examples or sites have shown you starting from complete scratch. This is all and well if you have the time to completely re-write an existing application for 6+ months or have started a v1 product. Right, in the "real-world" the former rarely happens and if your a developer wanting to stay on the bleeding edge, introducing a new architecture into an existing ASP.NET application is fairly tedious. From converting existing pages, supporting legacy routes, and possibly the lack of allowing multiple forms all prove to be a challenge. (Read More...)

ASP.NET MVC - Using Post, Redirect, Get Pattern

2008-05-09T05:57:01Z

The ASP.NET MVC pattern tends to lead itself into a more simplified and "true" HTTP experience by re-introducing patterns that have been lost, or at least, not followed in many years. One such pattern is the Post, Redirect, Get (PRG) pattern in which it is "to help avoid duplicate form submissions and allow web applications to behave more intuitively with browser bookmarks and the reload button" (Read More...)
