A Survey of Popular .NET Inversion of Control Containers

by kevin 10/2/2008 6:30:00 PM

UPDATE: Gaja Kannan attended this presentation and gave me a great link to a post by Torkel Ödegaard concerning IoC container performance. Interestingly, of all the IoC containers out there, Torkel picked the same products as I did (plus StructureMap) for his tests. You can find the post at http://www.codinginstinct.com/2008/08/castle-windsor-dependency-lookup-and.html. Thanks, Gaja, for the link! 

On Thursday, October 2, 2008, I gave a presentation to the Richmond .NET User Group entitled "A Survey of Popular .NET Inversion of Control Containers". It covered Microsoft Unity, Ninject, Castle Windsor and Spring.NET. I talked about the history of the development of Inversion of Control (IoC) and Dependency Injection (DI). I demonstrated the concept in a sample application (linked below). I also discussed Aspect-Oriented Programming (AOP) and how it can be used to create highly cohesive, loosely coupled applications. The slide deck and code is available at the links below.

Richmond Code Camp 2008.2 Program Handout

by kevin 9/29/2008 8:44:00 PM

I've been so busy planning for Richmond Code Camp 2008.2 on October 4, 2008 that I've been unable to blog over the past couple of weeks. But, because of what I've been working on, the program handout for the Code Camp is ready now. You can download the Adobe Acrobat file from here:

http://richmondcodecamp.org/RCCDocuments/Richmond+Code+Camp+2008.2+Program+Handout.pdf

If you are coming to Richmond Code Camp, you can download this document and plan out your day by looking at the speaker bios, abstracts and schedule. Keep in mind that we may have to make last minute changes to the schedule but, it's looking pretty solid right now. If you still need to register, you can do so here:

Richmond Code Camp 2008.2 Open for Business

by kevin 9/6/2008 8:00:00 PM

If you follow my blog, you can see that I haven't been blogging much over the past two weeks. OK, I haven't been blogging at all. I switched jobs and I've been spending every spare moment besides getting ready for Richmond Code Camp 2008.2 on October 4th, 2008. The registration page for the code camp is up and running as well as a 15-minute survey of the presentation tracks. The survey is important to us because it will help to determine the probable popularity of each of the 43 presentations that our speakers have prepared. At the new Learning Technology Center at J. Sargeant Reynolds Community College, we have rooms that will hold as few as 15 attendees, some that will hold 50 and an auditorium for the really popular presentations that will hold hundreds of Code Camp attendees.

Please take 15 minutes to fill out the survey if you plan on attending the Code Camp, OK? And make sure you register early. We have a beautiful new venue with a lot more space that we had before but we also have 35 top notch local and regional speakers coming from 9 states to present to us. Invitations are going out soon to the Greater Richmond Technology Council members and to all of the faculty and staff of the local Virginia Community College System. So, if you plan to attend, don't wait to register.

For those of you who've been encouraging me to restart my posts on Exploring the F# Language, I promise that the next installment is on the way. Thanks for your encouragement.

Josh Carlisle and His Best Friend Fred

by kevin 8/7/2008 9:45:00 PM

Josh Carlisle spoke to the Richmond .NET User Group this evening on Sharepoint Development for ASP.NET Developers. He was carrying what looked like a flask of vodka with him which made me think, "This is a guy I've got to hang out with." It turned out to be Fred Bottled Water. Unfortunately, I didn't get a picture of Josh with Fred, but here are pics of both of them. Doesn't Josh look unusually happy? He swears it was water of "exceptional purity with a high degree of virginality." Yeah, right.

Josh Carlisle speaks to the Richmond .NET User Group on 7 August 2008

Josh's presentation was very good. He was a bit perplexed near the end because of SharePoint's pesky insistence on treating the term MasterPage differently from MasterPages (plural). Pfft! SharePoint is so picky like that. Anyway, we had a good time and Josh was just great. He really knows his stuff. He's welcome back to Richmond at any time. Maybe I could get him up here for Code Camp on October 4, 2008. We got to see Nas Ali, too, who travelled to Richmond with Josh, I think. Always good to see Nas. He confirmed with me that he will be speaking for us at the upcoming Code Camp. Nas is a good speaker and his talks are not to be missed.

Thanks again Josh for coming to Richmond!

Accessing Web Services from Silverlight 2

by kevin 7/10/2008 10:39:00 PM

I presented tonight (10 July 2008) to the Richmond .NET User Group. We had a pretty good turnout, I'm guessing 40 to 45 developers. I gave this same presentation at my office today as a dry run and as a training opportunity within the company. It's so good to see the developer community eager to learn. I've attached my slides and the three demonstrations projects I used in this post. I'll be giving this same presentation to the Charlottesville .NET User Group next Thursday (17 July 2008). The abstract we put on both user group websites follows:

Silverlight is a client-side technology. So it’s not really a part of your SOA strategy, right? You may want to think twice about that. SOAP and WSDL support are coming to the web desktop via Silverlight. And Silverlight has good client support for REST+ JSON/POX and RSS/ATOM-based web services, too. During this discussion, we’ll dive into data serialization, security and cross-domain access policy capabilities inside Silverlight 2 Beta 2. We also talk about the nuances and pitfalls of provisioning your web services for an Internet audience. This presentation will be heavy on coding, demonstration and interactive discussion.

Powerpoint Presentation (289KB)

Twitter solution showing how to invoke a cross-domain RESTful service by way of an in-domain SOAP service bypassing the cross-domain access policy problem. (842KB)

REST solution showing how to create RESTful services in WCF and how to consume RESTful services in Silverlight (307KB)

Silverlight syndication solution showing how to consume cross-domain RSS and Atom feeds using the SyndicationFeed class. (11KB)

MVP Award for 2008

by kevin 7/2/2008 6:30:00 AM

I received Microsoft's MVP Award yesterday. I tried blogging about the experience at the end of the day but I didn't feel that I was ready to do it. The MVP Award is an unusual and very different kind of designation in the professional world. Many professional awards are about recognizing accomplishment. But the Microsoft MVP Award is about recognizing service. When you are singled out in this way, it's the community's method of saying, "Keep up the good work."

I've achieved many certifications in my career. I've held certifications from Sun, Oracle, IBM, Microsoft, HP, Siemens, Cisco and a few others. But I've never advertised them publicly because they were all my doing. I studied. I worked hard. I passed the certification exams. And I was a better developer and software architect for doing it. But, as a professional, I think those things are expected of me. So there was really no sense in wearing those certifications on my sleeve, in my opinion. To paraphrase the old adage, the proof is IN the pudding, not ON it, if you know what I mean.

The MVP Award, based on community and industry service, is not something you apply for. You get nominated by other MVPs and you go through a process of demonstrating what you've been up to for the past year. A review board checks you out (you can't hide from the search engines) and determines which MVP area of expertise you would fit into. Then, they determine among the other candidates in your group if your contributions to the community are exemplary. My MVP area of expertise is Visual C#, by the way. I think they picked the correct area for me because I know, love and promote the dickens out of C#. It's my favorite programming language in my career of 25 years so far.

It's a bit overwhelming to get the kind of support you need to win the MVP Award. When you receive "the magical e-mail" as some have called it, there's a stark moment of realization that you're standing on the shoulders of so many others who contributed to it. No MVP has ever achieved the title on his own. And I'm certainly no different. That's the way communities work. We lift each other up. I want to recognize a few folks who have lifted me up and encouraged me along the way to serve better within the Microsoft developer community:

These folks are my role models. In particular, I want to recognize Andy Leonard. If we weren't about the same age, I'd call Andy my techno-Dad. He's a father figure to all of us in the mid-Atlantic user group community, I believe. Andy is humble and brilliant, a rare combination. He's also the hardest working person I know. If I could follow Andy's lead to 50% efficiency, I know I would be successful, too. We are sorry to be losing him to Atlanta soon but he's leaving us in great shape. Thank you, Andy.

I send out a heartfelt thanks to these folks and the cast of hundreds who pour their time and energy into making the user groups, Code Camps and DevCamps throughout the mid-Atlantic region great successes. My profession would be just a job if it weren't for all of you. I look forward to serving you all in the year to come.

Going to CodeStock

by kevin 6/22/2008 7:55:00 PM

CodeStock LogoOK, I broke down and registered for CodeStock. That'll be a long drive. But the schedule looks awesome. This is a Code Camp on steroids in Knoxville, Tennessee. Lots of heavy hitters coming in to speak this time: Jeff Prosise, Alan Stevens, Steve Andrews, Todd Anglin, Rachel Appel, James Avery and many more.

Looks like I'll be riding there and back with Justin Etheredge. Spending some time with Justin will make the time go by faster.

The date is 9 August 2008 and the cost is $25. Hope to see you there.
