How is the management of roles and rights of participants implemented in your project?

Management of roles and participant rights in a project on C# is usually implemented through an authentication and authorization system.

A common approach is Role-Based Access Control (RBAC):

• Each user is assigned one or more roles (e.g., Administrator, User, Moderator).
• Access rights to resources and actions are defined for each role.

In ASP.NET Core, this is implemented through attributes:

[Authorize(Roles = "Admin")]
public IActionResult AdminPanel()
{
    // Code for admins
}

Claims-based authorization can also be used, where rights are set through claims.

Databases with tables for users, roles, and their relationships are often used to store roles and rights.

A user management service can be implemented in the project, allowing to assign roles, change rights, and check access at runtime.
