Updated Silverlight Unit Test Framework bits for Windows Phone and Silverlight 3

27 May 2010

Here are updated quasi-official unit test framework bits for Silverlight 3 and Windows Phone developers. These are not intended for Silverlight 4 developers, since the same framework built for SL4 is included in the April 2010 Silverlight Toolkit.

This brings the new features from the Silverlight 4 version to developers who have a business reason to continue with Silverlight 3 development for the time being:

  • Updated user interface
  • Integrated “tag expression” support for selecting subsets of tests to run
  • Performance improvements
  • Removal of dependencies on XLinq and System.Windows.Browser assemblies

These are also the bits you want for Windows Phone testing.

Why wasn’t there one for Silverlight 3 already?

Since the April 2010 toolkit release was targeted for Silverlight 4 developers only, these bits were not released for version 3 (though were built from the same source).

Why doesn’t the April 2010 toolkit work for Windows Phone development & testing?

The Windows Phone development environment is based on a version of Silverlight 3 today, and so that means that you need to use Silverlight 3 binaries and class libraries when re-using Silverlight apps and code – not Silverlight 4.

These bits work well for phone developers and replace the older bits I had posted to my MIX talk site.

Download the binaries

You may need to ‘unlock’ the binaries for security reasons once downloading and extracting the assemblies from the .Zip. To do this, right-click on the file and select the ‘Unlock’ button.

These binaries are strong named as before, but are not Authenticode signed, so they are not official. This helps work around some Windows Phone signing issues I’ve heard reports of.

Hope this helps,
