  You can try :

  var query = (await _identityUserRepository.GetQueryableAsync())
        .AsNoTracking() // add this
        .WhereIf(!string.IsNullOrWhiteSpace(input.Filter),
            x => x.Name != null &&
                 x.Name.Contains(input.Filter));

  It seems like you are missing a namespace using.

  You can reference the Volo.Abp.EntityFrameworkCore package.
