I work on Windows Azure Mobile Services at Microsoft.

  • Using Azure Mobile Services in a Windows 8 App

    Hi Robert,

    Great video!

    To query the customers table by ID and only get one result back, you can use customerTable.LookupAsync(customerId) - this will throw an exception if it fails to find a record with the specified ID so its more like Single rather than SingleByDefault.

    You mentioned that you want SingleOrDefault, but the code in your constructor assumes that you have a valid reference, so this makes me think that LookupAsync is exactly what you want (better to get an exception that says "no customer with ID: 999 found" than simply a NullReferenceException).

    One more tip: don't refresh the entire Azure portal when you just want to see if your data has been saved! There is a refresh button on the bottom of the page when you have the browse tab open. Its much faster Smiley

    Hope this helps,

    Paul

  • iOS Support in Windows Azure Mobile Services

    @Adam Cooper:

    Thanks for your great questions!

    1. At the moment we see some developers working with their script directly within the UI while others write scripts in a separate editor and paste them in. We are working on a command line interface for Mobile Services which includes direct script upload - expect to hear more about this very soon.

    When it comes to local testing, the most common pattern used at the moment is to extract as much of your logic as possible into a seperate object or set of functions and to unit test those. Unfortunately we do not have a local test environment or harness that you can use to test the entire script.

    When it comes to debugging, you can use the console object to write to your logs which are available on the 'logs' tab in the portal. This is very useful when it comes to figuring out what is going wrong in a script.

    2. There is a bunch of existing functionality that scripts can access using require(). We run scripts in node.js so standard node libraries like 'querystring', 'crypto', etc are all available for scripts to use. There are a few other libraries that we also make available - for example you can require('request') to get a great library for working with HTTP, and require('sendgrid') in order to send emails via the popular SendGrid service.  

    When it comes to reusing your own code, we recognize that we do not really enable this yet beyond copy/paste and we are actively working on addressing this issue.

    3. JavaScript is the only supported server side language for Mobile Services right now, but that may change in the future. We have heard from a number of developers that they would like to be able to use C# instead as you suggested. I would encourage you to go to our user voice and vote for this if its important to you!

  • Building real-time web apps with WebSockets using IIS, ASP.NET and WCF

    Hi Fred, I wrote a blog post that covers how you can try out the samples using the Windows 8 developer preview:

  • Building real-time web apps with WebSockets using IIS, ASP.NET and WCF

    Hi Dominic! I understand where you are coming from, but WebSockets is a new feature for IIS 8.0. At this stage there is no plan to support earlier versions of IIS. 

  • Building real-time web apps with WebSockets using IIS, ASP.NET and WCF

    Correct. You would get something like a "PlatformNotSupportedException". 

    If you'd like step by step instructions in setting up a Win8 preview machine and running the samples we showed in this talk, they are now available on my blog:
