Hello,
my goal is to develop an own form designer using the Visual Studio Integrati
on Package.

So far I proceeded as follows:
I have created a new "VS integration Package project"
I use C # as language
I set the integration package option to "Custom editor"

When the package runs a form is provided
some Items are added to the VS Toolbox

These items are to be dragged on the form later on.

My problem is that all ToolboxItems are disabled (shown in grey color). Is
there a possibility to enable them?
Why are they disabled anyway?

TIA
