votes

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!

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...

As @Dan Auclair points out, you can download the SDK and gain access to these dll. Download from http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=d197f51a-de07-4edf-9cba-1f1b4a22110d

For Silverlight 5 Version: 5.0.5.0 runtime Version: v4.0.30319

I needed the System.Windows.Interactivity.dll available from this install http://www.microsoft.com/en-gb/download/details.aspx?id=9503

It lets you choose where to install it but once it had finished it came up in the .NET tab under Add References...

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