Question

This confusing feature in ReSharper claims to let you browse external sources from within Visual Studio, see External Sources (ReSharper Web Help).

But, I don’t understand what values to set for the folder substitution option. (Resharper – Options – External Sources – Advanced)

When I try navigating to source, I keep getting the message:

PdbNavigator: No sources found in debugging information for in assembly

(This is almost a duplicate of Stack Overflow question Visual Studio – Attach source code to reference, but that post did not explain HOW to attach external sources.

Answer 1

This is tricky, and I finally figured it out:

1. Click “Show current path settings and PDB files binding” and look at where the PDB points to for source.
2. Add a folder substitution where the source code is where the PDB says the source code is (probably a path not on your computer, but on the system that compiled the DLL file and PDB). Set the target to the source you downloaded.

Here’s a screenshot:
