Improve HealthVault query efficiency with final transforms…

A while back I wrote a post about using the built-in HealthVault transforms to get a different view on your data. That post discusses the mtt, stt, and form transforms.

Mobile HealthVault Apps and Sync

I have been working with some developers working on mobile applications that connect to HealthVault, and the issue of synchronizing data between the mobile device and HealthVault has come up a couple of times.  We’ve come up with some guidance around this area and I’d like to share it more widely. I’m assuming that the…

A movie scene

Anybody who has watched movies about software development knows that reality is much different. None of us work with huge screens on the wall, and debugging is a lot of unexciting detective work. Today, we were doing some remote debugging over live meeting in a conference room, trying to figure out why an interaction between…

Default parameters in C#

From an internal discussion we’re having on the advisability of using default parameters in C#: Currently, the pain and limitation of doing overloads forces you to rethink how a method should work. Consider the following:  Process(int a); Process(int a, float b); Process(int a, float b, string c);   If I now need to change how…

Writing Tests for HealthVault Applications

We have added some useful new functionality designed to make it easier to test a HealthVault application. The existing HealthVault SDKs didn’t make it easy if you wanted to write isolated (or method-level) unit tests for features that talked to the HealthVault Platform. You could usually do it by designing your own layer that could…
