In a previous post I showed how to unit test an ASP.NET WebAPI Controller. But with a REST service there is both a client and a service component. Assuming for a moment the client part is also written in C# we should test that as well. In this case the client application contains the following class...

One of he goals of the ASP.NET WebAPI is to make REST style API controllers more testable than more traditional WCF services where in the past. For the most part that is true but there are cases where an ApiController depends on the actual incoming request and its data and things can become a bit more...

Back in 2010, I wrote a course for Pluralsight on OData which covers the protocol in general and introduces the viewer to the client and server programming model. This year, Microsoft released updates to the ASP.NET Web API which includes support for OData in the controllers.  Since this latest...

Some time ago I posted a blog post on Tincr and live reloading of CSS/JavaScript in Google Chrome. This works really well with one exception, on Windows 8 it will not install. When you try Chrome shows the following error message: This application is not supported on this computer. Installation has been...

The standard workflow with web development is run the web application, make some changes to your CSS in Visual Studio, flip back to the browser and reload the page to see the effect. While this works relatively well it can be somewhat slow at times.   One improvement is make changes to your CSS...

With REST there is not a lot required on the client as far as sending requests goes. As long as you can send HTTP GET requests you are good to go and there are very few programming stacks that don’t allow for some form of doing that. Of course just doing an HTTP GET is going to give you some data back...

  In the previous blog post I demonstrated how to get started with the ASP.NET Web API and retrieve some products data from the Northwind database. Something that was really easy to do But quite often we want to update data just as much as we want to retrieve it.   A quick recap of REST and...

Some time ago I did a number of blog posts about the beta versions of the WCF Web API . As it turns out the WCF Web API team has moved into the ASP.NET team, a good thing as far as I am concerned, and as a result it is now called ASP.NET Web API . Now this is much more that just a name change. For starters...

I’ve been part of several conversations over the past few weeks where someone posited the question: Now that WebAPI is out, how do I (or my customers) decide when to use it or WCF? This question actually has many different flavors? Is WCF done? Does WebAPI replace WCF? Should I stop using WCF HTTP? Why...

In deze, tijdens de TechDays opgenomen, podcast spreekt Maurice de Beijer met Steve Sanderson over de toekomst van web development met de moderne browsers. Ze spreken ondermeer over Knockout.js, een JavaScript library die MVVM stijl databinding mogelijk maakt binnen HTML/JavaScript applicaties. Je kan...

In the previous blog post about Knockout.js I showed why and how to get started with Knockout.js. And I explained that the reason I really like Knockout.js is that it is a very familiar way of working with its MVVM style. I created a small demo where we could update the first and last name of a person...

Using Entity Framework Code First together with SqlServerCe is a great way to work with small databases in ASP.NET MVC applications. I have several web applications running on shared hosting sites where SqlServerCe is the database engine under the hood. Deploying is also quite easy. I typically use the...

Consider the following problem: You might be tempted to start working with HTML5 features in your web applications but you have to support older bowsers.   So for many HTML5 features there are polyfills available that will let you make older browsers like Internet Explorer 7 or 8 work with the newer...

Services are becoming more important with richer HTML5 style applications. But by default the browser will let you call into a service on the originating domain but not another one. And that means you have to include all your services one the same domain, not very practical. And worse if you want to...

In previous blog posts I wrote about using Server-Sent Events so send data from the server to the browser. This works but has the drawback that it is a one way messaging from the server to the browser. There is nothing preventing you from doing ajax style calls back to the server but basically you are...

I’m working on a Windows Phone project that requires me to surface up multiple RSS feeds as a single source. I needed a way to do this quickly and easily, and with a little help from friends on Twitter (particularly a suggestion from @bertcraven) I found a nice way to accomplish this using the SyndicationFeed...

In the previous blog post I demonstrated how to use Modernizr to test for the availability of HTML 5 features. Doing so was quite easy but as every test is always performed to add CSS classes to the <html> element there is a bit of overhead in using the default Modernizr JavaScript file. Fortunately...

Yesterday I blogged about using the new Server-Sent Events or the EventSource object to send messages from the server to the client. But what happens if I try to do this in a browser that doesn’t support Server-Sent Events? If I run the code from yesterday in Internet Explorer 9 I sill see the following...

There are a lot of cool new features and one of these is Server-Sent Events . According to CanIUse.com Server-Sent Events are usable on almost half of the modern browsers. And as is often the case Internet Explorer is the big missing piece again. But fortunately there are some nice polyfills to take...
