I'm running into the error in the subject and I've tried to fix it for hours now but with no result so far.
I have a Visual Studioproject wizard (Create new project - select project template) and I want to implement this wizard into my software factory.

I'm kind of know my way arround in the GAT but I can't seem to fix this.
In the recipe I've specified the custom wizard page. like this:
<GatheringServiceData>
<Wizard xmlns="http://schemas.microsoft.com/pag/gax-wizards" SchemaVersion="1.0">
<Pages>
<Page Type="MyProject.CustomWizardPages.MyWizardPage,MyProject" />
</Pages>
</Wizard>
</GatheringServiceData>

I know the references are ok, otherwise I would get a different error.
So it looks like the runtime cannot find the constructor, while I can verify it is there and marked public.
Could it be it has something to do with the fact that the custom page doesn't inherit from "CustomWizardPage" but from"Microsoft.BizTalk.Wizard.WizardPage"?

Anyone?

The complete exception is this:

I sort of found a solution.

The class should inherit from CustomWizardPage but it is more important to have the correct constructor:

public MyCustomPage(WizardForm parent)
: base(parent)
{
// This call is required by the Windows Form Designer.
InitializeComponent();
}

Without this constructor it gives the error.

That is correct, you need to inherit from GAX's CustomWizardPage and you need to provide a public constructor with the specified signature so GAX will be able to instantiate this through reflection.
