logo_awsIt looks like Amazon is marching towards IaaS-domination with the release of an SDK for .NET.

It’s interesting that they only support C# and not VB.NET. You would think that since there are more VB developers they could more bang for their buck by offering both languages. Perhaps VB.NET is on the roadmap.

“The AWS SDK for .NET makes it even easier for Windows developers to build .NET applications that tap into the cost-effective, scalable, and reliable AWS cloud. Using the SDK, developers will be able to build solutions for AWS infrastructure services, including Amazon Simple Storage Service (Amazon S3), Amazon Elastic Compute Cloud (Amazon EC2), and Amazon SimpleDB. With the AWS SDK for .NET, developers get started in minutes with a single, downloadable package complete with Visual Studio project templates, the AWS .NET library, C# code samples, and documentation.”

The SDK requires Microsoft .NET Framework 2.0 or later only supports the following editions:

  1. Microsoft Visual Studio 2008 Professional Edition or later
  2. Microsoft Visual C# 2008 Express Edition
  3. Microsoft Visual Web Developer 2008 Express Edition

Be still my beating heart… it’s finally arrived! No more view states and post backs. It will finally be fun to do .NET web development again. I love C# but hate postbacks and view states!

ASP.NET MVC 1.0 Released!

We have a rather large Org with 600+ Page Layouts. When Visualforce came out we had a number of requests from our business units for customized layouts. After about 3 weeks of hand-coding Visualforce pages I soon realized I needed a better way to communicate these change as well as manage the code modifications. Being that I am relatively lazy by nature, I decided that I needed to develop a way to make my computer do the work that I didn’t want to do.

Generate Visualforce Pages

The C# code that I wrote utilizes the Metadata API and inspects the Page Layout for a specified Object and Recordtype and generates similar Visualforce code that you can paste into the Force.com IDE. Is it perfect? No. Could it have been done better? Yes. Does it save me time, money and aggravation? Most certainly!

It also saves me time during the change management process. Now when a BA or Project Manager modifies an existing Page Layout that I have used for a Visualforce page, I don’t need documentation on what fields have changed, I just point my handy-dandy generator at the Page Layout and regenerate the code.

The ASP.NET MVC RC is now available and I am so excited that I can hardly stand it! At work we do alot of .NET development but I cannot stand the ViewState and Postback paradigm. I’m been tinkering around with with ASP.NET MVC for quite awhile and have a couple of prototypes under my belt. According to the post, the 1.0 version should be released sometime in Febraury.

I’ve been seeing alot of posts on non-.NET sites with positive feedback. I think ASP.NET MVC may make it easier for Java developers to switch to the “dark side.”
