[Decision Needed] Path A: Investigate upgrading H5 to support .NET Standard 2.1 APIs

[MelbourneDeveloper]

Problem Statement

H5 currently only supports .NET Standard 2.0 APIs for transpilation to JavaScript. DataProvider uses modern .NET 9.0 with dependencies that require .NET 6.0+ APIs. We need to determine if H5 can be upgraded to support .NET Standard 2.1 APIs.

Current State

• H5 version: 24.11.53878
• Latest H5 version: 26.2.64289
• H5 transpilation: DISABLED due to React hooks + API incompatibility
• Dashboard.Web targets netstandard2.1 but H5 only transpiles netstandard2.0 APIs

Investigation Tasks

• Test H5 26.2.64289 to see if it supports netstandard2.1 APIs
• Check H5 GitHub/docs for netstandard2.1 support roadmap
• Test if newer H5 fixes React hooks incompatibility
• Document which netstandard2.1 APIs (if any) are now supported

Success Criteria

• Clear answer: Can H5 transpile netstandard2.1 APIs? Yes/No
• If YES: This is the preferred path (no need to downgrade DataProvider)
• If NO: Must use Path B (downgrade DataProvider to ns2.0 APIs)

Mutually Exclusive With

• Path B (Issue to be created): Downgrade DataProvider to .NET Standard 2.0 APIs
