I’ve just returned from the Build 2014 conference in San Francisco where I had the opportunity to attend several interesting sessions about new developments in the Microsoft space.
One of the “big news” has been the introduction of the concept of “Universal Windows Apps“, a great way to share code between different platforms including (but not limited to) Windows Phone, Windows Store and Xbox One apps.
I decided to test this new feature on TypedMVVM, one of my “pet projects” which I made available on CodePlex some time ago. The project was originally using a simple MVVM infrastructure targeting Windows Store apps using WinJS and TypeScript so it was an ideal candidate for adding a Windows Phone 8.1 target reusing all the existing code.
The migration to Universal Apps was really straightforward: I was able to have the samples up and running in my emulator and devices while waiting at the airport in San Francisco.
I’ve uploaded all the source code on Codeplex here, feel free to grab and give it a try.
Happy universal coding everyone! 🙂
Have you already tried TypeScript?
There’s been a lot of buzz about it in the last period and, while playing with this new language, I have created a new project on CodePlex – TypedMVVM – for experimenting how TypeScript could be used in a real world scenario by applying separation of concerns via the MVVM pattern in a simple Windows Store navigation app developed with WinJS.
- designData – services implementation for design-time data in order to enable “Blendability”;
- interfaces – interfaces for Services, ViewModels and ViewModelFactory;
- libs – TypeScript definitions and TypedMVVM core classes (in particular RelayCommand<T> and ViewModelBase);
- services – concrete services implementations used by the ViewModels;
- viewModels – concrete ViewModels implementations;
- views – views definitions.
The first impression is very positive: static typing is a must-have for writing complex apps and enabling features like refactoring or intellisense. Language features like interfaces, classes, generics and lambda expressions permit the developer to write code more readable, maintainable and extensible.
I’m planning to add more features and helper classes to this sample in the future whilst waiting for the final release of TypeScript so stay tuned!

Today I’ve been honoured to receive my 5th MVP award from Microsoft for my contributions about Client Development and related technologies during the last year.
It’s always a great emotion receiving the award: I would like to thank all the people that supported me including the smart guys working in Microsoft, my MVP lead Cristina González Herrero, the members of the “Insiders” lists and, of course, my family.
Happy Client Development everyone!
I already blogged about NDepend basic features here: I was positively impressed by the capabilities of this tool by fellow MVP Patrick Smacchia.
NDepend permits you to examine .NET projects and highlight different metrics in the code in order to better analyse what areas of your solution needs refactoring for improving performance, code maintainability, application stability and applying best coding practices (just to name a few).
Some features, already available in the previous versions of NDepend, include tools for visually representing dependencies between classes, defining custom rules on code, explore code diffs and analyse code coverage. These ones are particularly helpful when the size of the project grows: a visual representation helps the developer to better identify areas that needs more work (and then save development time).
Recently Patrick contacted me for highlighting the new features available in NDepend v4.1. I was very pleased to find support for Windows Store apps but another capability got immediately my attention: CQLinq.
This is a killer feature: CQLinq (acronym for Code Query LINQ) enables the developer “to query the code” for retrieving information about it. Some simple examples of queries could be:
- find me the methods too big / too complex;
- find the methods added but poorly covered by tests;
- get information about naming conventions;
- any other query you like: the possibilities are not limited at all!
Technically these queries can be constructed using the traditional LINQ syntax and the types defined in the NDepend.CoreModel of the NDepend API.
The best place to start using CQLinq is here by exploring the dedicated section on the site which contains a ton of different examples to start: I recommend to try and run the available samples which are an excellent starting point and then modifying them for custom queries.
I’ve been really impressed by CQLinq and I can’t wait to use it on real projects to enhance the quality of the code and then reduce the time needed for new implementations.
Happy coding everyone!
I’ve received several requests for publishing the MultiTouch Behaviors on the NuGet gallery so I created a simple package containing support for the Windows Phone and Silverlight platforms.
To enable your project for MultiTouch, just run the following command in the Package Manager Console and all the libraries and dependencies will be added to the Visual Studio project:
PM> Install-Package MultiTouchBehaviors
Alternatively just search for the package selecting Tools->Library Package Manager->Manage NuGet Packages for Solution from Visual Studio 2012.
If you are interested in creating a NuGet package for your open-source project, register an account here in the gallery and follow the instructions described in the section “Creating and Publishing a Package“: they are very clear and contain detailed information about the process.
The package definition for MultiTouch is also available in the Source Code section on CodePlex.
As you may know, the Microsoft Patterns & Practices team has recently released the final version of “Prism for Windows Runtime“, available for download here on CodePlex.
This project contains a complete guidance for building Windows Store apps using C# and XAML and includes the following resources:
Big kudos to all the p & p team: they did an amazing job and I personally felt honored to have the possibility of providing feedback whilst the project was in development.
This is really a great guidance for building Windows Store applications that can be easily tested, maintained and extended: every developer building complex apps will benefit from it.

Happy coding everyone!
The last week has been very exciting for Microsoft developers: The //build/ conference in Redmond was full of amazing content including Windows 8, Windows Phone 8 SDK, Microsoft Surface, Xbox SmartGlass, Kinect for Windows and the new language TypeScript.
Unfortunately I hadn’t the possibility to participate at the conference but had some free time during the week-end to watch some of the recorded sessions available here on Channel9: this is really a great resource and I suggest everyone interested in Microsoft technologies to download some videos and have fun with it.
I decided then to take a look at the new features available in Windows Phone 8 and the related SDK: Justin Angel has a great article about this topic in the Nokia Developer Community.
To get my hands dirty I moved then on my personal Open-Source project “Multi-Touch Behaviors” on CodePlex: this is a set of Epression Blend Behaviors for different platforms including Windows Phone, Silverlight and WPF for applying gestures and manipulations (like the one available in the “old” ScatterView control) to generic XAML elements.
The project was not yet updated to Windows Phone 8 so I took this opportunity and experimented with the new SDK: this was really a great experience since I was able to upgrade quickly all my samples to the new platform using the same codebase used for the Silverlight version.
Unfortunately I haven’t the possibility to test the performance on a real Windows Phone 8 device at the moment but the first impressions are really positive.
I have already checked in the code for WP8 here, I’m planning more testing and development in the future.
Happy XAMLing everyone 🙂
Today I’ve been honoured to receive my 4th MVP award from Microsoft for my contributions about Silverlight and XAML related technologies during the last year.
Every new award is always a great emotion; I would like to thank all the people that supported me including the smart guys working in Microsoft, my amazing MVP lead Alessandro Teglia, the fantastic groups of the insiders lists and the “terrific” Silverlight MVPs. You all rock.
Enjoy and continue XAMLing everyone, big times ahead!
