Technical Evaluation Framework: Vetting Mono & Cross-Platform .NET Specialists

Mono enables .NET application execution across Linux, Android, iOS, and embedded devices. Vetting Mono specialists requires assessing legacy compatibility and modern .NET convergence.

1. Mono Architecture & Cross-Platform Runtime

• ▸
  Mono Runtime & Embedding: Embedding the Mono runtime within C/C++ applications, game engines (Unity), and POSIX environments.
• ▸
  Ahead-of-Time (AOT) vs. JIT Compilation: Configuring Full-AOT compilation for platforms restricting dynamic execution (iOS, game consoles).
• ▸
  Modern .NET Migration Pathways: Migrating legacy Mono-based systems toward unified modern .NET (NET 8/9).

2. Buyer Diligence & Vetting Criteria

1. ▸
   Memory & Garbage Collection Tuning: Profiling Mono SGen garbage collector, heap sizes, and diagnosing native-managed memory leaks.
2. ▸
   Native P/Invoke Interoperability: Safely marshalling data structures across managed C# code and native C/C++ shared libraries.
3. ▸
   Cross-Platform Build Tooling: Building and packaging Mono applications using MSBuild, Make, and automated container pipelines.

3. Red Flags to Watch For

• ▸
  P/Invoke Platform Inconsistencies: Marshalling native libraries with platform-dependent assumptions, causing crashes on Linux or ARM targets.
• ▸
  JIT Reliance on AOT-Only Platforms: Using dynamic reflection or code generation on platforms that mandate Full AOT, causing runtime crashes.
• ▸
  Ignoring Modern .NET Unification: Maintaining legacy Mono runtimes for applications that could run faster and more securely on modern .NET Core.
