Missing System.Windows.Interactivity in Silverlight 4 - mvvm light tutorial

Question

Hi, I'm trying to follow this MVVM Light Toolkit V3 Alpha 2: EventToCommand behavior tutorial.

I'm using vs2010 with silverlight 4. I dont have expression blend.

The tutorial states that

In addition, you need the System.Windows.Interactivity.dll

I don't seem to have this: I can't see this when I try to add a reference. Anyone know how I should get / add it?

Thanks in advance!

Answer 1

Usually it is located here:

C:\Program Files\Microsoft SDKs\Expression\Blend 3\Interactivity\Libraries\Silverlight\System.Windows.Interactivity.dll

But if you don't have expression blend then...

Answer 2

Just noticed that the dll is included the download zip from the tutorial.

Answer 3

Or you could just install a 60 days evaluation of blend 4. Nice to use when you are using MVVM light.
