Web Camps Training Kit – September Edition

The Web Camp in Los Angeles was a great success last Friday with Phil Haack, Jon Galloway and myself imparting a raft of knowledge on ASP.NET MVC 2, jQuery, Entity Framework Code-first, ASP.NET MVC 3 and Razor.  However, there’s little time to pat ourselves on the back – because this week marks the launch of the September Edition of the Web Camps Training Kit!

Online and available as a download

The previous version of the Web Camps Training Kit was only available as a download, but we listened to your feedback and are now publishing it online too!  Choose your flavor below:

What’s new in the Web Camps Training Kit – September edition?

The goal for Web Camps is to provide great training events and an accompanying Training Kit so that web developers have thing they can rely to build websites and apps on the Microsoft Web Platform.  To be a complete web developer, you have to understand many different types of technology, not just the server side.  You also need to know technologies like jQuery, OData and when/how to leverage Web Apps like Umbraco, Kentico, DotNetNuke and more.  As things move so fast, you’ll also need to keep in touch with the latest developments in HTML 5 and how to take advantage of them in the websites you build.

So, in the September edition we are starting to introduce some new technologies areas that help you to keep on the cutting edge.  This is only the beginning and in future editions we will be constantly adding to future versions of the Training Kit.  Here are some new things I would like to highlight:

  1. jQuery

    Working with the .appendTo() team we’ve put together 3 jQuery sessions with presentations, demo scripts and source code.  This content covers some of the fundamentals of jQuery and then extends using Ajax as well as jQuery Templates and jQuery UI.
  2. IE 9 & HTML 5

    With the IE9 Beta just out the door, we’ve provided you some presentations on how to develop on IE9 as well as some of the enhancements the team have made on performance.  This is useful background material and we’ll be following this up with more content in the next release.
  3. ASP.NET MVC 2

    The ASP.NET MVC 2 content has been refreshed and we’re now basing all the content off the MVC Music Store.  There are presentations, labs and demo scripts that walk you through build the site and we’ve also provided a bonus lab on how to start adding Tests to the project.
  4. Web Apps

    The beauty of Web Apps are that they install really easily and they get you to 80% of a completed solution with little effort.  You can customize and tweak them the rest of the way for your own requirements to build complete solutions for customers is no time at all.  In this release we’ve teamed up with Umbraco, Kentico and DotNetNuke to provide presentations, videos and labs for you to get started building solutions.

  5. OData

    OData is the new standards-based web protocol for querying and updating data.  If you are writing an API for your website, it’s worth seeing how you can leverage OData to give developers a clean and familiar way to access your data.  Or, if you are interested in consuming one of the many OData services out there then there are a bunch of SDKs out there to get started in your language.  We provide an intro presentation into OData with more content coming soon to help you learn the programming syntax.

Phew – there’s lots of new content in this release and it’s been fun pulling it all together.  We’ll continue to add more as well as update existing pieces as they become out of date.  Of course, if you have feedback we’d love to here it – please get in contact here.

Don’t forget about the events – you can get expert training by registering for a Web Camp here.  We will be releasing a raft of new event dates very soon.  We are going large – stay tuned!

Announcing the OData Helper for WebMatrix Beta

I’m a big fan of working smarter, not harder.  I hope you are too.  That’s why I’m excited by the helpers in WebMatrix which are designed to make your life easier when creating websites.  There are a range of Helpers available out of the box with WebMatrix – you’ll use these day in, day out when creating websites – things like Data access, membership, WebGrid and more.  Get more information on the built-in helpers here.

It’s also possible to create your own helpers (more on that in a future blog post) to enable other people to use your own services or widgets.  We are are currently working on a community site for people to share and publicize their own helpers – stay tuned for more information on that. 

Today we are releasing the OData Helper for WebMatrix.  Designed to make it easier to use OData services in your WebMatrix website, we are open sourcing it on CodePlex and is available for you to download, use, explore and also contribute to.  You can download it from the CodePlex website.

  1. @{
  2. var result = OData.Get("http://odata.netflix.com/Catalog/Genres('Horror')/Titles","$orderby=AverageRating desc&$top=5");
  3. var grid = new WebGrid(result);
  4. }
  5.  
  6. @grid.GetHtml();

 

What is OData?

OData, or as I like to call it “Oh…. Data” Winking smile, is an open specification that makes it possible to have consistent APIs for all the different services out there.  Effectively it’s REST with a powerful query syntax that makes it easy to extract the data you want from a service.  So far there are a bunch of websites out there that have exposed their data using the spec, including Facebook, Netflix, Stackoverlow etc.  There’s a full list over at www.odata.org as well as more information on the spec itself.

How to use the OData Helper

The OData helper supports CRUD (Create, Read, Update and Delete) methods – as you would expect -  but for reading there are a couple of syntaxes available; use the one which feels most natural to you.  Here are a couple of examples of the different syntaxes:

Get the top 5 Horror Titles (Using String Filters)

 

  1. @using Microsoft.Samples.WebPages.Helpers
  2. @{
  3. var result = OData.Get("http://odata.netflix.com/Catalog/Genres('Horror')/Titles","$orderby=AverageRating desc&$top=5");
  4. var grid = new WebGrid(result);
  5. }

 

Get the top 3 Movies in French (Using Query Syntax)

 

  1. @using Microsoft.Samples.WebPages.Helpers
  2. @{
  3. var result = OData.Open("http://odata.netflix.com/Catalog/Languages('French')/Titles")
  4. .Where("Type eq 'Movie'")
  5. .OrderBy("AverageRating desc")
  6. .Top(3)
  7. .Get();
  8. var grid = new WebGrid(result);
  9. }

 

Inserting new data
  1. @using Microsoft.Samples.WebPages.Helpers
  2. @{
  3.    var movie = OData.CreateEntity();
  4.    movie.Name = "OData Helpers – The Movie";
  5.    movie.ReleaseYear = 2010;
  6.    movie.BoxArt.LargeUrl = "http://cdn-4.nflximg.com/us/boxshots/tiny/5670394.jpg";
  7.    OData.Insert("http://odata.netflix.com/Catalog/Titles", movie);
  8. }

Updating existing data

 

  1. @using Microsoft.Samples.WebPages.Helpers
  2. @{
  3.    var movie = OData.Get("http://odata.netflix.com/Catalog/Titles('13kaI')");
  4.    movie.Name = "OData Helpers – The Movie";
  5.    OData.Update("http://odata.netflix.com/Catalog/Titles('13kaI')", movie);
  6. }

 

Deleting existing data
  1. @using Microsoft.Samples.WebPages.Helpers
  2. @{
  3.    OData.Delete("http://odata.netflix.com/Catalog/Titles('13kaI')");
  4. }

With Netflix service the insert, update and delete operations won’t work because they only provide read access – so the examples above are just for illustrative purposes only.

If you are new to the OData query syntax I would recommend checking out the docs that the OData team have put together.

What can you do?

There are bunch of OData services out there (full list here), why not create some wrapper classes for each service with common operations baked in so other developers don’t even have to know the syntax.  You’ll see what I mean if you explore the sample application in the download section of the CodePlex project.  We’ve included a Netflix.cs file in app_code folder – it’s just a wrapper around the OData helper class which performs some commonly used queries for the user.  I’d love to hear what you can do!

Next Steps

OData Helper v2

We’ve already cooked up some enhancements for the next version of the OData helper, you can find the list here.  If you think of anything you would like to see, please reply to the discussion in the forum!

Other Helpers

I’m now working on some other helpers which I think are pretty cool – you’ll hear more about them soon.  I’d love to hear about your ideas for helpers – maybe I can build it for you!  If you have an idea leave me a comment or send me mail – james {at} microsoft.com
