Build Add-on projects without SAP B1 SDK installed?

Hello, Experts

  I want to build our project in a machine without SAP B1 SDK installed. So I tried below steps.

1. Use TypeImp to create a interop DLL for the UI API COM object.

2. Reference the Created interop DLL in the ADD-ON project instead of adding the COM reference in Visual studio.

Because the DLL contains the all the type information, so we can compile the add-on successfully.

But the problem came when we are trying to use this add-on in SAP. The SboGuiApi.Connect(sConnectionString); method always fails during addon connection.

Can anyone told me how to resolve this issue?

Thanks in advance.
