An Interview with Warnygo Developer Vivien Chevallier

1)Have you developed Apps for any other platforms before? If Yes What are they?

We previously have developed WM 6.5 applications with .Net compact framework.

2)Why did you choose WP7 as a platform of your choice?

We are primarily .Net developers working everyday with all technologies around the .Net Framework.

That’s why when we had a first look to Windows Phone 7 at MIX10 in march, we have been very enthusiastic.

Finally WP7 is a natural choice for us, because when you are a .Net developer working with Silverlight you already are a WP7 developer, the transition is really easy!

3)Which one do you think as the single most feature you liked in WP7?

We like to be able to create a Silverlight application on a mobile phone easily with a great integration with Bing map control and the cloud.

4)Are you satisfied with WP7 Platform development tools?

Because of the tools currently in a beta version we have to play with the bugs sometimes, but we are globally satisfied.

Visual Studio 2010 and Blend 4 are great to develop WP7 application, we’re not confused at all!

But we advise developers to be careful in difference between emulator performance and device performance.

5)What are the Apps you are developing now in WP7?

We are currently developing Warnygo an application that lets you send alerts out to the world.

This application/concept is based on three pillars : Mobility, GPS, Microsoft Notification Service. That’s make our application more efficient.

We can totally see Warnygo taking "social networking" to another level.

We are trying to develop a vocabulary around the application that everybody can understand. For example, an alert is named a “Warny”.

6)In what way Microsoft can improve their WP7 or What does WP7 lacks from?

We’d like to be able to retrieve the video stream through the camera because we are currently only able to retrieve a picture.

A great feature would be to give the possibility to integrate a Windows live account with the applications.

Microsoft should also add the copy/paste feature.

7)Future Plans of you?

Warnygo is developed to be presented in a competition organized by Microsoft France and one of the judge will be Steve Ballmer.

This competition is a way for us to be spotted and get support to launch Warnygo.

Apart from these questions, Other things you want to share with the community?

Warnygo developers are not selfish! That’s why we want to share with the community our development tricks.

For example one of us, Nicolas, explains on his blog how to cache data or how to have binding on the ApplicationBar. More details here:

We are colleagues developing this application during our spare time (by that I mean evenings and weekends). So if you like our concept, just tell us! This is a great motivation and reward for us.

Thanks Vivien for sharing with us.
