When migrating from Xamarin to .NET MAUI, robust data security and intellectual property (IP) protection are paramount. Ensure secure migration by implementing end-to-end encryption, secure storage mechanisms, OAuth-based authentication, and HTTPS for all API communications, while maintaining compliance with GDPR, HIPAA, and other relevant regulations. For IP protection, implement code obfuscation, secure proprietary business logic, and rigorously review third-party dependencies. Post-migration, enforce controlled app distribution, establish continuous security monitoring, and maintain strict licensing compliance to safeguard your application’s integrity.
