Now I testing these features and willing to buy licenses..
Anyway, My testing environment is "Visual Studio 2008, project codes are written in C# ", and already installed VintaSoftImaging .NET SDK 5.0,
and imported dll files(Vintasoft.Imaging, Vintasoft.Annotation) in Project's References.
I want to put "AnnotationViewer" into Panel at Design Mode, but there are no AnnotationViewer element (and whole VintaSoft element) in Visual Studio Tool Box.
(Usually in design mode, drag element or user controls from toolbox and drop them to panel or forms... am I getting wrong? )
How can I see them in Visual Studio ToolBox?
I also opened AnnotationDemo Project, and saw annotationViewer1 is in the splitterPanel. But in there, I can't see VintaSoft controls in toolbox.
Let me know how can I handle this.

Thank you for reading.
