Hi,
[quote user="clever_anthony"]I guessed this was similar to Adapter[/quote]
Based on what facts did you make such guess? It's mentioned in ToolSettingsHost class documentation that it inherits HostedControl ... which is evidently not Adapter. Using a proper tool like JustDecompile you can navigate through the whole inheritance chain to PresentationFramework assemblies.
[quote user="clever_anthony"]But I was not able to compile it. Upset.[/quote]
It's not surprise it cannot be compiled, classes inherited from different parents cannot be interchanged.
[quote user="clever_anthony"]Anymore hint?[/quote]
I recommend to study existing sources of information, e.g. WPFDemo example contains code using ToolSettingsHost class (it's key-in "wpfdemo open4").
With regards,
Jan
