From f602c5c7120f87f517d28105b281013caa8bd380 Mon Sep 17 00:00:00 2001 From: "copilot-swe-agent[bot]" <198982749+Copilot@users.noreply.github.com> Date: Thu, 19 Mar 2026 19:02:51 +0000 Subject: [PATCH 01/14] Include requesting assembly info in assembly load failure exceptions When an assembly fails to load, the FileLoadException/FileNotFoundException now includes the name of the requesting (parent) assembly in the FusionLog property. This helps diagnose dependency chain issues by showing which assembly triggered the failed load. The information flows from the native AssemblySpec::GetParentAssembly() through EEFileLoadException::CreateThrowable() to the managed exception's FusionLog property, which is displayed in ToString() output.

Add an integration test in System.Runtime.Loader.Tests that creates a real dependency chain (Root -> Mid -> Leaf) where the transitive dependency (Leaf) is missing at runtime. The test verifies that a FileNotFoundException is thrown with the correct missing assembly name when the chain is exercised.

<198982749+Copilot@users.noreply.github.com> Date: Fri, 20 Mar 2026 18:24:52 +0000 Subject: [PATCH 09/14] Fix test: remove incorrect Root assertion and verify test passes The test was asserting that the exception message contains both "MissingDependency.Mid" and "MissingDependency.Root". However, the runtime only includes the immediate requesting assembly (Mid) in the FileNotFoundException message - not the full transitive chain. The chain-building code in clrex.cpp:1735-1762 only propagates when nested EEFileLoadException inner exceptions exist, which doesn't apply in this single-level missing dependency scenario (Leaf fails to load, requested by Mid). Verified: the test now passes with the rebuilt runtime.
