Why does Silverlight 4 Tools only give partial intellisense?

I finally got Silverlight 4 Toolkit installed , referenced and working after the difficulty of finding the right namespace described in this question.

But intellisense doesn't work fully: after I type "tk:", it doesn't pop up the various controls I have available, but if I type a control name out, e.g. DockPanel, then it works, as shown below. It will even give me intellisense after I type tk:DropPanel, which is odd.

How can I get intellisense to work in all cases for the Silverlight 4 Toolkit?

I can imagine I need another namespace, but this site says that this reference:

is now all you need (and will be automatically used by both Visual Studio and 开发者_高级运维Blend)

Here is a screenshot from Silverlight 3 Toolkit intellisense which has always worked well in both vs2008 and web dev express 2008:

Confirmed.

This appears to be an issue with the Silverlight Toolkit assemblies, as this does work for the SDK assemblies.

If I were you I'd file a bug up on connect @ Microsoft Connect

In the meanwhile, I'd recommend considering using Resharper to supply your Visual Studio intellisense as using the Ctrl+Space key combination in resharper does provide intellisense at this point.
