Heads up! #msdyn365BC devs, Microsoft just updated their docs on code signing.

If you're publishing .app files, the rules are now stricter. Certificates using newer standards must be signed via secure hardware like Azure Key Vault or FIPS-certified USB tokens.

❌ No valid signature? No AppSource. Even for on-prem, unsigned extensions now require explicit verification skips.

Signing options:
✔️ Azure Key Vault (recommended)
✔️ .PFX file (legacy support only)
✔️ Self-signed certs (local dev or on-prem only)

📦 Whether you're shipping to AppSource or deploying internally, make sure your signing setup is compliant.
