The applications referenced on the left require the Microsoft .NET 3.0 Runtime. If
you don't already have the runtime installed you will automatically be asked
to download it. The download and installation could take anywhere from 5 to
30 minutes depending on your computer's configuration and your internet connection.
(The download is only required the first time.)
Some of the links below are to XAML Browser Applications (XBAP). As of the time of this writing, these applications only run on
Internet Explorer (version 6 and later). XBAPs run inside your internet browser as a page which you can navigate away from at any time.
The other applications are ClickOnce deployments where the application will be downloaded from the server and executed
on your machine outside of the browser. Typically the install is straight forward, and no cleanup needs to be done after you are done using/testing it.
If you are not automatically offered to download the Microsoft .NET 3.0 Runtime (and you
don't already have it), you can install it
from here.
