- You disclose the dependency at the beginning of the description metadata.
- Dependency on non-Microsoft provided driver(s) or NT service(s) is not allowed. If your product has a dependency on non-Microsoft provided driver(s) or NT service(s), you must disclose that dependency to Microsoft in the certification notes in Microsoft Partner Center to be considered for an exception to this policy.
It is recommended that you add a note in the description that this app requires .NET Framework 4.8.1 Thank you.
