I have created .Net usercontrol in C#. it is graphical control with a text box and listbox.
Now I want to use this control in legacy VC++ application.(native binary).
means i want to call manage code from unmanage code.

suppose my usercontrol name is xyz.dll.
I generated tlb file using tlbexp.exe and then i registered this control using below command line.
regasm xyz.dll /tlb:"C:\xyz.tlb" /codebase

I have checked my control using 'Activex control test container' (open studio 2005 and go to 'tools' menu)
I tested my .Net usercontrol on this tool and it worked fine.

then I created a sample C# window application. Under Toolbox, I right click and selected 'Choose Iteams' and selected
"COM component" tab. and choose my xyz.dll control.
now this contol is added into toolbox.

But when I drag this control onto window then i got below error.
Failed to create component 'AxHost'. The error message follows:
