Measuring startup performance when using .NET Native Developer Preview

by

I got really excited about .NET Native technology last week when I first heard about it during Build. I wanted to measure performance in my Windows Store apps to see how it can improve it (especially startup times!), and in order to do that I was going to user EventSource and PerfView. Unfortunately, something didn’t work, but the team helped me go around it!

MetroGridHelper performance with Windows 8.1

by

MetroGridHelper is a small helper class for XAML WinRT apps developed by Mark Monster which helps build perfectly aligned apps. As far as I remember, the idea for a metro grid helper goes back to early Windows Phone 7 development and a version for Windows Phone by Jeff Wilcox (Mark also credits him in his blog post). I’ve been noticing performance issues with it in Windows 8.1 apps during loading. Basically, splashscreen stays on much longer. Even though you should only be using MetroGridHelper while testing your apps so it won’t make you fail during certification, it can still be somewhat annoying if you’re testing your app a lot. If you’re seeing the same issue – here’s how to fix it!

Augmented reality with GART – what’s changed on Windows Phone 8

by

I wrote an article a year and a half ago about using GART with Windows Phone to create augmented reality scenarios in really easy steps. It’s linked in the GART project documentation and it gets a lot of attention and even questions from people working on Windows Phone 8 apps. The article was written with Windows Phone 7 in mind, but conidering it’s still being used as reference getting started implementation, I decided to write about what has changed.

Create with Nokia, win prizes and get noticed

by

I love Nokia and Windows Phone. And I love what Nokia has been doing for Microsoft mobile platform and especially for all the developers investing their time and energy to develop for the platform which is growing, but is still not at the point where we, developers, would want it to be. One of the things Nokia is doing at the moment is the Nokia Create global competition.

Focus a TextBox from ViewModel using a simple behavior

by

Let’s assume a simple scenario – you have a Windows Phone page connected to a ViewModel (VM) with everything bound nicely. A TextBox text property is connected to a string in VM, and when you change it, you wish to put focus on the TextBox. How to accomplish this considering that all your logic is actually in the VM separated from the View? Simply, using a focus behavior.
