Hi one and all,
I located a really nice open-source docking solution called 'AvalonDock' on codeplex, and downloaded v1.1, and included the dll in a WPF project in VS2010 Beta 2 (targeting .NET 4.0) - so far so good.
Then I saw that V1.2 was available and it fixed exactly the issue I was having (V1.2 exposes a DP called DocumentsSource on the DockingManager, so I can keep it cleaner MVVM-wise)
So I downloaded the binaries for V1.2.2691, removed the old reference, included the new one and now I cannot for the life of me "see" the library at design-time...
In my Window's XAML, I type in 'xmlns:dock=' and wait for intellisense to present me with a list of namespaces/assemblies... they all appear, but AvalonDock is conspicuous by its absence! If I manually type in the reference (cos I know it's there!) and carry on blindly, the xaml designer complains about missing references and such, but the App builds and runs as expected...
What am I missing? Thanks for your suggestions, IanR
