Add Custom Web API Endpoints To Check Permissions & Query Media Data in .NET MAUI Apps with EF Core
In this video (Part 4), we will review the previously created XAF Web API Service and .NET MAUI mobile apps, and extend them with additional UI-related functionality:
modify the Add button behavior based on user role permissions;
add the Photo editor to the mobile form based on the media data retrieved from the secure data service.
For both scenarios, we will extend our Web API Service with custom endpoints that will respect security rights for different user roles. These basic capabilities of our Web API Service are available free-of-charge - register your free copy today at https://www.devexpress.com/security-a.... Check out the related videos:
