Hi,
You can try with below code:
List listManager = new List();
listManager = (from user in await _context.UserMaster.Where(p => p.RoleId ==3).ToListAsync()
select user).Select(p => new RMangerViewModel() {
UserId = p.UserId,
FirstName = p.FirstName,
LastName = p.LastName
}).ToList();

Hi,

You need to query first list and build new list object which you want to create,
