Lets say thers is one interface 

```
interface Ifoo
{
   HRESULT foo();
};

```

which is part of a binary dll. I dont have source code for this.

Can I put a breakpoint on foo() API exposed from the interface Ifoo of this binary dll using Windbg?

I know we can put breakpoints on binary dll's using windbg but using COM I am not sure.
