I am porting from .NET 4.8 to 5.0 a report designer that features a drag and drop design surface and uses WinForms. Everything works except for this.
I also ported from .NET 3.5 to 5.0 this project (https://www.codeproject.com/Articles/24385/Have-a-Great-DesignTime-Experience-with-a-Powerful) and everything works except for this.
Using dotPeek to step into the .NET 5.0 code I got as far as DesignerHost.CreateComponent, but I didn't find the method that throws the exception.
Expected behavior:
DesignerHost.CreateComponent returns the requested component
Minimal repro:
- create a Windows Forms App using .NET 5.0 Framewok
- create a class DesignSurfaceExt that inherits System.ComponentModel.Design.DesignSurface
- initialize DesignSurfaceExt by calling ServiceContainer.AddService(typeof(INameCreationService), _nameCreationService);
- call rootComponent = (Form)designSurfaceExt.CreateRootComponent(typeof(Form), new Size(640, 480));
expected: CreateRootComponent returns a new Form
actual: DesignerHost.CreateComponent throws NotImplemetedException with message 'This method/object is not implemented by design.'
