Overview

Simple tool to extract data from PDB files and serialize it to JSON for ingestion by other applications.

Usage

• Paths are hardcoded (edit Program.cs).
• Output is written to current working directory in the form {targetName}_{targetHashSha256}.json.
• If you hit an access exception when trying to load a PDB, try running as an administrator.
