The Microsoft HealthVault SDK comes with a few sample applications and ApplicationIds which you can use in order to explore the platform and even to get started on your own application. But at some point in your application development process, you will want to customize your ApplicationName and Logo. You may also want to use additional data types or methods that the sample ApplicationIds cannot use.
The application configuration for these sample ApplicationIds is controlled by Microsoft and we want to keep these configurations in a known-good state for other developers, so you cannot modify these configurations. Luckily it is easy to create your own ApplicationId that you can then configure as you see fit. There are two options for how to do this:
Easiest way: If you have access to a computer running Microsoft Windows then you can use the HealthVault Application Manager client.
Harder way: you can also create your certificate using a client application such as MakeCert.exe on Windows systems, and then upload it to Application Configuration Center yourself. The process to create and install your certificate pair is outlined in detail in this article. To actually create the ApplicationId in the HealthVault-PPE environment, look for the create a new application link within the Application Configuration Center.
