Eager loading use Include got error in .Net - eager-loading

Question

I'd like to display the 'ApplicationRole' Name with the 'ApplicationUser' data together using Eager loading.
here is my ApplicationUser
public class ApplicationUser : IdentityUser
{
public string? Name { get; set; }
public string? Department { get; set; }
public bool IsDeleted { get; set; }
public string RoleId { get; set; }
public virtual ApplicationRole Role { get; set; } = new ApplicationRole();
}
public class ApplicationUserDTO
{
public string Id { get; set; }
public int UserId { get; set; }
public string Name { get; set; }
public string UserName { get; set; }
// Foreign Key
public string RoleId { get; set; }
public virtual ApplicationRoleDTO Role { get; set; } = new ApplicationRoleDTO();
}
here is ApplicationRole
[NotMapped]
public class ApplicationRole : IdentityRole
{
public string Id { get; set; }
public string Name { get; set; }
//[InverseProperty(nameof(ApplicationUser.Role))]
public virtual ICollection<ApplicationUser> Users { get; set; } = new List<ApplicationUser>();
}
public class ApplicationRoleDTO
{
public string Id { get; set; }
public string Name { get; set; }
public virtual ICollection<ApplicationUserDTO> Users { get; set; } = new List<ApplicationUserDTO>();
}
and here is the UserRepository
public async Task<IEnumerable<ApplicationUser>> GetAllUsersAsync()
{
//return await _dbContext.User.Where(u => u.IsDeleted == false).ToListAsync();
return await _dbContext.User.Include(u => u.Role).Where(u => u.IsDeleted == false).ToListAsync();
}
public async Task<ApplicationUser> GetUserAsync(string id)
{
return await _dbContext.User.Where(u => u.Id == id).Where(u => u.IsDeleted == false).FirstOrDefaultAsync();
}
But when I use the 'Include' keyword it show this error
When I try to use the string "Role", it also show error
public async Task<IEnumerable<ApplicationUser>> GetAllUsersAsync()
{
return await _dbContext.User.Include("Role").Where(u => u.IsDeleted == false).ToListAsync();
}
Here is the error show
