How to Submit Azure AD B2C NEW User Submission in MVC App - azure

Question

Loving Azure AD B2C... Looking forward to when it is out of preview!!!
Have a special case I need help putting my head around.
I have a page where I capture new email addresses via a web form.
After adding that email to my mailing list, I want to then create an AD B2C account automatically without making the user click any additional buttons using my ASP.NET MVC Site.
In reading the Article at: https://azure.microsoft.com/en-us/documentation/articles/active-directory-b2c-devquickstarts-graph-dotnet/
I see that it is possible to add a new user using the Graph API.
However, this example is written using a cmd program.
Does anyone know if there is some sample code to allow me to insert a user into AD B2C inside an MVC controller?

Heres some sample code on how I do it from ASP.Net MVC. Remeber that you need to include ClientId and Clientsecret (they are separate from the ASP.Net webapp) as explained in the article you mention. Code from controller--helperclass:
UserController:
// POST: User/Create
[HttpPost]
public async Task<ActionResult> Create(b2cuser usr)
{
try
{
usr.AlternativeSignInNamesInfo.First().Value = string.Format("{0}_{1}", usr.FirstName, usr.LastName);
usr.DisplayName = string.Format("{0} {1}", usr.FirstName, usr.LastName);
string json = Newtonsoft.Json.JsonConvert.SerializeObject(usr, Formatting.None);
Utils.GraphAPIHelper api = new Utils.GraphAPIHelper(graphAPIClientId, graphAPIClientSecret, tenant);
string res = await api.GraphPostRequest("/users/", json);
return RedirectToAction("Index");
}
catch (Exception e)
{
return View();
}
}
And in the GraphAPIHelper:
internal async Task<string> GraphPostRequest(string api, string json)
{
AuthenticationResult result = authContext.AcquireToken(graphResourceID, credential);
HttpClient http = new HttpClient();
string url = aadGraphEndpoint + tenant + api + "?" + aadGraphVersion;
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, url);
request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", result.AccessToken);
request.Content = new StringContent(json, Encoding.UTF8, "application/json");
HttpResponseMessage response = await http.SendAsync(request);
if (!response.IsSuccessStatusCode)
{
string error = await response.Content.ReadAsStringAsync();
object formatted = JsonConvert.DeserializeObject(error);
throw new WebException("Error Calling the Graph API: \n" + JsonConvert.SerializeObject(formatted, Formatting.Indented));
}
return await response.Content.ReadAsStringAsync();
}
And finally, some samplecode from the model, pls note JsonProperty(Order:
public class b2cuser
{
[JsonProperty(Order = 0, PropertyName = "accountEnabled")]
public bool AccountEnabled = true;
[JsonProperty(Order = 1, PropertyName = "alternativeSignInNamesInfo")]
public List<AlternativeSignInNamesInfo> AlternativeSignInNamesInfo { get; set; }
[JsonProperty(Order = 2, PropertyName = "creationType")]
public string CreationType = "NameCoexistence";
