How can I see what the "unresolvable conflicts" are when renaming something in Visual Studio?

Question

I'm trying to rename a C# namespace in Visual Studio 2015, and after a moment Visual Studio helpfully (?) tells me there are 216 unresolvable conflicts.

That's all the information it seems to provide, though.

How can I see what these conflicts actually are?

The preview button doesn't show anything obvious.

Answer 1

I have spent a lot of time but concluded that there is no way to see the conflicts but in all of the encounters I found out that it is because of one of the Documentation Comments Tag. The rename somehow is unable to rename values inside these tags.
