Paste your REST API definition as strong types

If your a developer that spends any time with web services, you’ll basically probably end up working in one of two camps: REST- or SOAP-based services.  Now with SOAP services you’re likely used to having a WSDL document describing the service, providing type definitions, etc. – something you can use developer tools like Visual Studio to Add Service Reference and get a strongly-typed object model to work with. If you’ve been doing Silverlight or ASP.NET (or any other technology really) development with mashup services, you probably have been working with REST-based services.  These are services that don’t self-describe themselves in...

Troubleshooting data/service access in Silverlight

A while back I pondered doing a “live” debug session with people who were/are working with Silverlight 2 and data access via services, etc.  I really like a live concept because it allows people to ask real questions and feels more conversational than a one-way presentation.  After some consideration, I’m not sure I could quite guarantee the environment I was looking for to accomplish this type of style. So as a second best, I’ve set up a webcast: Troubleshooting Silverlight Data Access.  I hope to keep the question channel open during the webcast though and answer as many questions as possible. ...

Updates to Amazon S3 and Silverlight

After posting my sample implementation of accessing Amazon Simple Storage Solution (S3) via Silverlight, I reflected quickly and also chatted with some AWS engineers. Cross-domain Policy One thing that you should never do is just deploy a global clientaccesspolicy.xml file blindly.  Often times in samples, we (I) do this.  I need to be better about this guidance to be honest, so I’ll start here.  As an example, for the S3 cross domain policy file, we really should add some additional attributes to it to make it more secure.  Since we know it is a SOAP service, we can...

How about some LIVE Silverlight service debugging?

I’ve got a thought lately and curious if I’m thinking crazy.  You see, probably the most asked questions I get are around working with services within Silverlight.  Although I’ve got some helpful (at least I think they’re helpful) posts on the subject: Silverlight, 404 and some tool help Updates for Beta 2 Working with Syndicated Data Calling WCF/ASMX Services Calling REST Services Cross-domain policy files ...

Silverlight cross domain services and a helpful tool

I’ve been getting a few notes on issues relating to people trying Silverlight beta 2 and WCF or other services.  The most common issue I’m seeing reported is “my exception is showing a 404-not found error message, but the service is there and works!” Okay, there could be several things happening here, but let’s tackle the “make sure it is plugged in” type situations.  I don’t mean to make light of the error, because at first I, too, was banging my head against a wall.  Sometimes it helps to have a second set of eyes or a deeper understanding...

Silverlight 2 Beta 2 updates for web services

We were all jumping for joy when Silverlight 2 beta 1 was released and the ability to connect to services was more readily/easily available to us.  For discoverable services that provided a WSDL we were quickly able to implement them using the Add Service Reference capability in Visual Studio 2008.  Beta 2 brings a few changes to the world of services that you should know about.  I’ll do my best to recap some of them here. Generating a WCF Service In beta 1 when we created a WCF service for use in Silverlight, we used the “WCF Service” template...

My Silverlight application cannot access my service!

I’ve started a dialog with a few of you about getting Silverlight and service integration working, specifically with ASP.NET web services (and even WCF ones).  A few have downloaded some of my samples, but others have started from scratch.  A few have reported getting some interesting errors, ASYNC_blahblah and NotFound errors specifically.  While this was boggling my mind (as I wasn’t getting them), a reader’s comments pointed me along the lines of something…he mentioned “maybe it is because my web service is ASP.NET 2.0 and not 3.5” – of which that shouldn’t be the case, so I went to test...

Calling services from Silverlight 2 part 2

In a previous post, I wrote about some samples of calling various types of services from Silverlight 2.  In the code, I was using constructors in my ASMX and WCF services with specifying a binding type and endpoint address. It was called out to me that in other demonstrations, people did not use this construct.  While the method I demonstrated works (explicitly specifying the binding and endpoint), in some cases it may not be necessary.  One such case would be if you only have one endpoint and it is basicHttpBinding. The error in my code/instructions was about changing the binding information in...

Calling web services with Silverlight 2

UPDATE: Source code posted here. Now that Silverlight 2 is out to the masses (even in beta form), there are likely a lot of developers looking to wire-up web services with their applications in .NET rather than the Silverlight 1.0 method of Javascript.  I thought I'd give you some quick examples of how to do this using some different methods: ASP.NET Web Services (ASMX), Windows Communication Foundation (WCF), REST service, and talk about cross-domain calls.  These are meant to be examples using very much 'hello world' style services, but demonstrating at least how to execute the call. If you are an ASP.NET...
