He right-clicked. . v11.1.0.2169 opened a new tab showing a call graph—red lines for missing references, green for internal. A blue node glowed: LegacyGPSBridge.GetApproximateRoadDistance . No implementation. Just a P/Invoke to a 32-bit unmanaged DLL.
That was the bottleneck.
[INFO] RouteOptimizer: Using ModernRouteOptimizer [INFO] Delivery ETA: 6.2 hours (previous: 8.7 hours) Leo leaned back. The trial still had three days left, but he didn’t need them. He opened the company credit card form and typed: .NET Reflector Professional v11.1.0.2169 – 1 license – perpetual with one year maintenance. .NET Reflector Professional v11.1.0.2169 -Win- ...
All they had were the compiled DLLs. Thirty-seven of them, baked in mystery.
The tree view exploded: namespaces, classes, methods. He clicked on the OptimizeDeliverySequence method. In the right pane, the decompiled source code materialized like a ghost writing itself. He right-clicked
public List<DeliveryStop> OptimizeDeliverySequence(List<DeliveryStop> rawStops) { // TODO: Replace with actual A* implementation // Gerald's note: Use Manhattan distance for city grid if (rawStops.Count < 3) return rawStops; var optimized = new List<DeliveryStop>(); // ... 200 lines of cryptic logic ... return optimized; } Leo squinted. Manhattan distance? Their trucks ran across rural Montana, not New York. That explained the bizarre fuel overages last quarter.
Your evaluation of .NET Reflector Professional v11.1.0.2169 (Win) ends in 3 days. A blue node glowed: LegacyGPSBridge
It was a gray Tuesday morning when the email arrived in Leo’s inbox.
Later that night, he sent a Slack message to the team: “Found Gerald’s hidden Euclidean bug. Also, never trust a TODO comment from 2016.”
He dragged RouteOptimizer.Core.dll into the workspace.
Leo opened Visual Studio, then launched . The splash screen appeared—a familiar deep blue with the stylized magnifying glass over a C# bracket. "Loading assembly cache," it said. Then, "Ready."
