I’ve submitted my first application for Windows Phone! It is very simple app. Marketplace has a good amount of similar apps: Planning Poker. Anyway, I’ve wrote couple own behaviors for TextBox and want to share this code with you.

If you are Silverlight/WPF developer and have already used Blend than you should know what are Behaviors and Interactions. If not or if you forget what is it I will remind you. You can find these libraries in directory “c:\Program Files (x86)\Microsoft SDKs\Expression\Blend\” (in case if you have Windows x86 than you should remove from path (x86)). And of course these libraries exist only in case if Blend has been installed. In this directory you can find packs of libraries for WPF/Silverlight and WindowsPhone. If you don’t know what are Behaviors and Interaction I suggest you to read Expression Blend SDK for Windows Phone on MSDN. In few words: this is approach to extend default control’s features, more than! this approach allows you to use MVVM pattern.

Let’s extend some features of default TextBox control.

Silverlight 4 in Action (Manning, Pete Brown) – this is second book, which I read about Silverlight. First was Pro Silverlight 3 in C# (Apress, Matthew MacDonald), which helped me when I was need to very quickly know more about Silverlight after WPF. After reading Silverlight 4 in Action I think that this is best book about Silverlight. But maybe I should compare this book with Pro Business Applications with Silverlight.

I think that most of Silverlight and WPF developers know book’s author’s blog Pete Brown. Since 2009 author is Microsoft employee, since 2007 Silverlight became the main technology of development for him. You can think that Silverlight 4 in Action is second edition, because Manning has also Silverlight 2 in Action, which I didn’t read. But Silverlight 2 in Action has different authors than SL4 in Action. So talk about what’s new in Silverlight 4 in Action is no good, it is different book, written by another author. Looks like this is first book of Pete Brown, and it is written very good.

After buying paper book you will get also free e-book version (pdf), which you can read with Kindle device for example (only in album rotation). The book has about 800 pages, has 3 parts and 25 chapters.

First time when I familiarized with unit testing was 5 or 6 years ago. It was start of my developing career. I remember that somebody told me about code coverage. At that time I didn’t write any Unit tests. Guy, who was my team lead, told me “Do you see operator if with three conditions? You should check all of these conditions”. So, after that I had written some code, I should go to interface and try to invoke all code which I wrote from user interface. Nice? At current time I know little more about tests and unit testing. I have not participated in projects, designed by Test Driven Development (TDD). Basics of my knowledge are a spying code of my colleagues, some articles and screencasts. I had decide that I should know much more, and became a real professional of unit testing, this is why I had start to read book The art of Unit Testing with Examples in .NET. More than, in my current job place looks like I’m just one who writing unit tests for my code. I should show good examples of my tests.
