Debug Managed and Unmanaged code together

Question

My main startup project is in c++. the solution involves also managed c# code. When I debug - I have breakpoints only on the unmanaged sections (on managed breakpoint it states : "The breakpoint will not currently be hit. invalid file line "

I checked the reference and saw that there is dll and pdb there.

What could it be?
