In C# there is the readonly keyword that enforced the rule that the variable must be initialised as it's declared or in the constructor. This works as expected for simple types, but for objects and lists it's not quite like that. With a list, you can still add, remove and change items in the list. You may also expose a list as a property with a public get and a private set. You want the owner class to be able to modify the list items, but you don't want anything outside the class to modify the list items.
Here is an example with an almost readonly list, but as you can see it's not as … more
In an earlier post I wrote about using an XML value provider to allow you to send XML to your .NET MVC action methods. This is great, untill you want to accept XML where you have a model that needs XML atributes to control how it's deserialized. As the value provider stage happens before mondel binding it has no knowledge of the model objects that the values will be pushed into. So it can't look at your model class's XML attributes.
In cases like this, you're better of using a custom XML model binder.
To setup an XML model binder you need to create a model binder and a model binder provider. … more
My previous C# mocking framework of choice was MOQ. It's very powerful and fairly easy to use, but I recently started using NSubstitute and fell in love with how easy and intuative it was to use.
The cleverest part is that unlike MOQ the mocks produced actually implement the interface they're mocking and this makes the code much clearer and a little bit shorter.
Here is a very simple example:
var mockThing = Substitute.For<IThing>();
// Use mock thing
In MOQ this is also quite straightforward but the setup code to … more
My Windows 8 app had a GridView with grouped content and also made nice use of semantic zoom to make navigating between those groups easy. All I wanted to do was to make the headers appear in the content like the People App. I thought this would be a simple case of finding the right container template to use, but after reading this post by Mike Taulty it turns out that using the group style built into GridView can't do this. His post goes into a lot of detail about how to figure out your XAML and shows a GridView with inline group headers. I've taken his method and extended it to include … more
If you create a new WinRT solution using the Grid or Split Application Template you'll get all the code you need to create a layout aware page that shows a different view when in snap view. If you start of your project using the blank project template, you need to do a little bit more work to get it working.
First you need to change the page to be a layout aware page. LayoutAwarePage is a class provided by the template and is in the Common folder. (Update: In Visual Studio 2012 RC LayoutAwarePage is no longer in the common folder for a blank page project. You need to copy the file from the … more
As I talked about in my post Do we need the repository pattern? I’ve been thinking about how we can make a testable data access layer with Entity Framework without using a repository pattern. I showed how you could do that in my post Mocking your Entity Framework data context and testing it in .NET MVC. However losing the repository also loses a nice centralised place to keep your query logic. In this post I’ll show you a nice simple way to use extension methods to do this.
Suppose you’re using Entity Framework to store a collection of foos and there are several places in … more
I explained in my previous post Do we need the repository pattern? why you might want to mock your Entity Framework context rather than using the repository pattern. In this post I'll show you how to do that and how to test your .NET MVC controllers with a fake data context.
The way you do this varies slightly depending on whether you're using code first or database first. I'll cover both in this post.
Using Code First in Entity Framework 4
My implementation of code first is based heavily on the blog post by Rowan Miller.

In HTML when you want to create a box around some content with rounded corners or some other nice feature it would be nice if you could just wrap that content in a <div> or a <section> tag and CSS would do the rest. However this rarely seems to be the case, particularly if you want the HTML to render well in older browsers. The views in my latest .NET MVC 3 project were full of repeated opening and closing sections of HTML for something that we called a chunk, which is just our word for a box with rounded corners that groups together related elements on the page. Sometimes a chunk … more
I'm excited about the possibilities that touch screens and multi-touch screens will give us. I'm also interested in HTML 5 and making something that will work accross a variety of devices whether they have a touch screen or just a mouse. To play about with both I'm currently making a colouring book app that will work on an iPad, a desktop computer's browser and hopefully any other touch enabled phone browser.
