This way i register my class file in maui program file

context.Services.AddScoped<FileName>();

This is that file code

public class fileName: IScopedDependency{
    private readonly IHttpContextAccessor _httpContextAccessor;
    private readonly interface1 _interface1;
    private readonly interface2 _interface2;
    private readonly interface3 _interface3;

public UserSessionService( interface1 interface1,interface2 interface2,interface3 interface3)
{
_interface1 = interface1;
_interface2 = interface2;
_interface3=interface3;
}
