Using Entity Framework Code First with Stored Procedures that have Output Parameters
I’m working with a team on a new customer project that uses Entity Framework Code First on the backend for CRUD operations. It’s been a nice ORM to work with since it really simplifies the process of mapping relational objects to CLR objects and lets you do it through fluent mappings. Working with Plain Old CLR Objects (POCOs) is something I’ve always liked since they keep the code base super clean and shiny. I can’t say that I really miss the .edmx files that I used previously with the database first or model first approaches.

T4 Metadata and Data Annotations Template
Awhile back I was working on an ASP.NET MVC 3 project that required a lot of “standard” validation to be performed (required fields, validate lengths, some regular expression validation here and there, data type checks, etc.). Due to the number of classes involved I decided to go with the data annotations approach to keep things nice and tidy (some people love this, some people hate it – such is life :-)). As I dug more into the project I realized it was a fairly monumental task to create a metadata class for each of my model classes so I ended up investing one night to create a Visual Studio T4 template that could generate all of the metadata classes automatically based on an Entity Framework 4 model. I published the project up on CodePlex to make it easy for other devs to get to but realized I never blogged about it. Here’s an overview of what the T4 metadata and data annotations template does.

Building the Account at a Glance HTML5/jQuery Application
As Web technologies continue to evolve developers are required to learn new technologies in order to build successful web-based applications that stand above the crowd. This can be a challenging proposition especially for developers moving from desktop or Rich Internet Application (RIA) development frameworks. To help developers learn the latest HTML5, CSS3 and JavaScript technologies, we built a sample application for demonstration at Microsoft’s MIX 11 conference called “Account at a Glance” (download the app below) which we’re now able to (finally) release. The application takes advantage of key web technologies and uses them to display brokerage account information to consumers.

Code Samples from the LINQ and .NET 3.5 Webinar
Thanks to everyone who attended the Maximizing Productivity with LINQ Webinar today and to ROI for putting it on. We had a great turnout and covered a bunch of technologies in an hour. I didn’t have time to go through the more detailed examples I had of using LINQ to SQL and Entity Framework so I’ve attached those along with the few slides I showed for the Webinar. If you have suggestions about future Webinars that you’d like to see please let me know.
