People Picker equivalent

[ajcaterino]

In PnP Core, what is the equivalent of this API: _api/SP.UI.ApplicationPages.ClientPeoplePickerWebServiceInterface.ClientPeoplePickerResolveUser?

We have our users assigned to groups and I can see that the group has been assigned to the sites; however, I have a scenario where some users are found for one site but not others. I am currently using the following code where loginName is "i:0#.f|membership|{Email}":

web.Load(w => w.SiteUsers.QueryProperties(s => s.Mail));

var siteUsers = web.SiteUsers.ToList();
if (siteUsers == null || !siteUsers.Any())
    _logger.LogWarning("{Method} - No site users found for site {Site}", LogHelper.GetClassAndMethod(), web.Url.OriginalString);

if (loginName.StartsWith("c:0t.c|tenant|"))
    return siteUsers.FirstOrDefault(u => u.LoginName.Equals(loginName, StringComparison.InvariantCultureIgnoreCase));

var mail = loginName.Split('|').Last() ??
    throw new Exception($"{LogHelper.GetClassAndMethod} - {loginName} format is invalid.");

// Get the user from the login name...
var siteUser = siteUsers.FirstOrDefault(u => u.LoginName.Equals(loginName, StringComparison.InvariantCultureIgnoreCase));
if (siteUser != null)
    return siteUser;

_logger.LogWarning("{Method} - User {LoginName} not found for site {Site}.", LogHelper.GetClassAndMethod(), loginName, web.Url.OriginalString);

siteUser = siteUsers.FirstOrDefault(u => u.Mail.Equals(mail, StringComparison.InvariantCultureIgnoreCase));
if (siteUser == null)
    _logger.LogWarning("{Method} - User {LoginName} not found for site {Site} by email {Email}.", LogHelper.GetClassAndMethod(), loginName, web.Url.OriginalString, mail);

@ajcaterino : you can use EnsureUserAsync on IWeb to resolve a user
