Hello. I’ve embedded unity 3d scene into my WPF application through Web Player COM interface and now I want to use classes from Microsoft.CSharp namespace in my unity project, but this namespace is available only for standalone build configuration. Is it possible to change webplayer libraries subset?
No its not possible.
The webplayer conforms to web application standards and refuses to use anything external even if you missuse it through the com interface.
Unity has technically no support for such a thing, but does not forcefully prevent you from doing it, but it still remains a “web player embedded in something else” with all the corresponding limitations
