  • Criticism

    I’ve played with art through my life, not enough to be a master, but occasionally enough to get better. While studying and practicing art for my A-Levels we were given a still life scene involving a skeleton and some barbed wire to paint. This is the perfect scene for inspiring a teenage artist (far better than fruit).We were being taught by a different teacher than normal. He was a bit intimidating. I wish I could remember his name. All I remember is that he told us that he specialised in punching clay while angry to make sculptures of people. He showed us some pictures of his work … more

  • Sharing your view model between Monogame and Xaml

    If you create a new Monogame Windows Store XAML Project. You will get a XAML page called GamePage.xaml and you'll get the monogame game class Game1.cs. If you want display data from your game class in XAML or if you want to take input from XAML into your game then these two sides are going to need to communicate.

    One way they can communicate is by sharing a view model. As the XAML page creates the instance of your game class, it can also let your game class know about it's view model. Like this in GamePage.xaml.cs:

    public GamePage(string launchArguments)

  • Real readonly lists in C#

    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

  • Adding a field to a content type in an Orchard data migration

    In Orchard you can create your own content type by welding together several content parts. Here is an example of how you'd do that in your data migration:


    cfg => cfg





    You can also add fields to a content type, but it's not obvious at first how to do this. You can't add a field to a type directly, you can only add fields to parts. To get round this you can add a secret part to a type with the same name as the type. This part is not shown in content … more

  • Business Model Canvas App for Windows 8

    A business model canvas is the lean alternative to a business plan. They say no business plan survives first contact with customers, so why write a large inflexible document. A business model canvas is supposed to give you at a glance the key important aspects and assumptions of your business. It shouldn't stay the same, but should change as you prove and disprove the assumptions your business model is based on. The idea comes from Alexander Osterwalder and he wrote about in his book Business Model Generation.

    I've been playing about with them for a few of my ideas and decided to create … more

  • Top Ten Windows 8 Apps

    The Creative Bloq App Generator Contest was sponsored by Windows 8 and was a chance for UK developers to be recognised for their excellent work. I was very pleased that my app Font Picker was one of the top ten winners, particularly because of the high quality of the other winners. Here are the all the winners of the contest.

  • Custom XML model binder for ASP.NET MVC

    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

  • Mocking with NSubstitute

    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

  • Record breaking fonts on vinyl

    Font Sunday is a weekly twitter phenomena where the typographically obsessed share examples of fonts around them. The theme this week was 'Fonts on Vinyl' and this turned out to be a theme that got people excited and it was the most contributed to week we've ever had.

    The Design Museum started Font Sunday and set the theme each week. I help out by collating the contributions on a Pinterest board. more

  • The Side Project Startup reading list

    This is the reading list for my talk, 'The Side Project Startup. I last gave this talk at DDD North 2 and it's slowly evolving every time I give it. If you're interested in side projects and starting your own small software business then this reading list is for you.
