Deterministic Compilation with Roslyn Analyzer

This Unity project is a reproducible project about the issue where "Deterministic Compilation" is disabled when Roslyn Analyzer is in the project.

The issue occurred in Unity 2020.3 and below, and has been fixed in Unity 2020.1.

Assembly structures

• AsmParent
• AsmChild (Assembly Definition References: AsmParent)
• AsmGrandchild (Assembly Definition References: AsmChild)

How the DeterministicCompilationTest works

DeterministicCompilationTest rewrites a private method in the source code in AsmChild. If "Deterministic Compilation" is enabled, only AsmChild will be recompiled.
