When are these Warnings not Warnings? Should I continue intrepid or become trepid?

When I build my project, I get a couple of "Consider app.config remapping of assembly" messages, and a more direly-worded, "warning MSB3247: Found conflicts between different versions of the same dependent assembly."

Yet, the final summation reports 0 warnings. Why is that? It warns me, then says all is well!

Here is the full dump for the curious:

So...should I worry about these notables, or shrug them off?
