* ! Reimplement SharedArrayPool because it is internal in .net runtime * ! Expose PublicArrayPool that maps to our copy of SharedArrayPool * ! CodeGenerator that remaps System.Buffers.ArrayPool.Shared calls to Sandbox.PublicArrayPool * ! Don't run ArrayPoolUpgrader in full engine builds * ! Add tests that verifies ArrayPool.Shared replacements * ! Remove ArrayPool.Shared from whitelist * ! Build AST from nodes instead of parsing text * ! Use Reflection to grab Gen2GcCallback instead of event polling
