I've posted my session slides and samples from my ASP.NET Connections sessions last week in Orlando. I did three sessions at the conference and you can check out the slides and samples here. All three sessions had extensive samples (and I didn't even get to them all) so if you attended my sessions be sure to take a look at the samples as there's lots of extra stuff that didn't get covered in sessions.

The files posted here are more current than the original code and slides provided at the conference and the immediate updates I posted. I spent a little more time cleaning up a few dependencies, hopefully making it a little easier to get the samples running. Please be sure to read the _readme.htm files (or the Configuration links on the default page) in each of the projects, as they include important information about set up to run the samples and setting up the databases.

Here are the links and summaries of each of the sessions:

Ajax Alternatives: Using jQuery with ASP.NET

This was by far the most fun session for me, partly because I've been working with jQuery so much in recent months, but also because it was a really interactive session. I started this session with a basic ASP.NET page and went through the motions of adding jQuery functionality to the page. In 10 minutes of hands on building up of the page I went through a wide cross section of jQuery from selector syntax to document manipulation, to special effects, using plug-ins and  creating an plugin. From there the session has samples that demonstrate basic Page based AJAX operation - Ajax without any sort of framework on the backend, followed by examples and some generic helper code that lets you use WCF 3.5's Ajax support with jQuery. Samples include demonstrations of HTML loading, using server based HTML templating (ie. poor man's UpdatePanel like behavior) and raw data results with JSON. The WCF examples provide mroe data driven examples which demonstrates the same examples, but using purely client side manipulation of the DOM with data from the server. The two examples use a stock quote server and portfolio display that is rendered and updated client side including a nice interactive display. I also showed a cool photo album application that shows off a few useful plug ins including sortables and an inplace editing component I created for doing real time and in place  data updates using the DOM as the data storage mechanism. Finally there is an example of a jQuery component (jquery.ui's DatePicker control) wrapped as an ASP.NET control for easier usage in the ASP.NET environment.

The photo album application is running on my site here:


and a demo that allows access to the admin functions the demonstrate the more interesting features can be accessed at this particular URL:


(this demo likely will get trashed by vandals since it allows user input and I'll probably pull it after a few days or so, so check it out now while it's there)

WCF 3.5 JSON and REST Services

This session's focus is on the new WCF 3.5 HTTP features that provide support for REST principles and AJAX support. WCF 3.5's AJAX support has been made nearly as easy and comprehensive as ASMX functionality and there are many options of how data can be accessed over HTTP now with official protocol support for the webHttpBinding. This session starts of with examples of pure REST URLS and demonstrates features like URL templating, different response formats (wrapped, bare, XML, Json) as well as the various different options for serving in this fashion. THere are also examples of serving up raw data such as images or HTML content out of the REST based API. The remainder of the session focuses on AJAX functionality and explores different ways that WCF services can be called. There's a comprehensive Stock Service example that shows simple stock quote retrieval, a more complex portfolio manager and streaming stock history graphs to the browsers. Examples are provided for using Microsoft ASP.NET Ajax as a client as well as jQuery as a client in order to avoid loading of Microsoft Client Libraries.

Building a LINQ to SQL Business Layer for ASP.NET Applications

Focus of this session is on a LINQ to SQL Business object framework that wraps LINQ to SQLs data access model. LINQ to SQL - although completely object based, is still little more than a sophisticated data access layer and so a business object layer is still needed to abstract business logic and provide common functionality that every business related entity requires. THe business layer provides a few high level abstractions to the CRUD layer as well as a host of low level features that allow better control for low level data access in case LINQ to SQL queries are ill suited for queries and operations that cannot be performed with LINQ to SQL at all. This session includes a simple but comprehensive Time and Billing example application that demonstrates many aspects of working with LINQ to SQL using this business layer.

This is an update to previous versions of the LINQ to SQL Business layer I've put out. Enhancements in this version include removal of the requirement for tables to have timestamp fields, several enhancements to dynamic expression usage internally and a few small bug fixes.
