Get email address of Microsoft Live account

Question

I'm using mvc5 + c# and i'm gives my user the option to log-in to my website with external login (facebook, google, ...).

I'm trying to add Microsoft Live a as new provider. But, I'm don't see any option to get the email address of the connected user.

I'm Getting those claims when some-microsoft-user is connect ("KEY | VALUE"):

http://schemas.xmlsoap.org/ws/2005/05/identity/claims/nameidentifier | ***************** 
http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name | test 
http://schemas.microsoft.com/accesscontrolservice/2010/07/claims/identityprovider | ASP.NET Identity 
http://schemas.xmlsoap.org/ws/2005/05/identity/claims/nameidentifier | **************
http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name | **************** 
urn:microsoftaccount:id | **************** 
urn:microsoftaccount:name | ****************
urn:microsoftaccount:access_token | **************************************************************

There are any option to get the email address of the user, using this information?

Answer 1

Yes, there are. After several hours of trying I managed to get it working like this:

Code in startup.Auth.cs

var ms = new Microsoft.Owin.Security.MicrosoftAccount.MicrosoftAccountAuthenticationOptions();
ms.Scope.Add("wl.emails");
ms.Scope.Add("wl.basic");
ms.ClientId = "xxxxxxxxxxxxxxxxxxxxxx";
ms.ClientSecret = "yyyyyyyyyyyyyyyyyyyyy";
ms.Provider = new Microsoft.Owin.Security.MicrosoftAccount.MicrosoftAccountAuthenticationProvider()
{
    OnAuthenticated = async context =>
    {
        context.Identity.AddClaim(new System.Security.Claims.Claim("urn:microsoftaccount:access_token", context.AccessToken));

        foreach (var claim in context.User)
        {
            var claimType = string.Format("urn:microsoftaccount:{0}", claim.Key);
            string claimValue = claim.Value.ToString();
            if (!context.Identity.HasClaim(claimType, claimValue))
                context.Identity.AddClaim(new System.Security.Claims.Claim(claimType, claimValue, "XmlSchemaString", "Microsoft"));
        }
    }
};

app.UseMicrosoftAccountAuthentication(ms);

Code in AccountController.cs, in function ExternalLoginCallback to retrieve the email address:

string Email = string.Empty;

var externalIdentity = await AuthenticationManager.GetExternalIdentityAsync(DefaultAuthenticationTypes.ExternalCookie);
var emailClaim = externalIdentity.Claims.FirstOrDefault(x => x.Type.Equals(
                                                    "http://schemas.xmlsoap.org/ws/2005/05/identity/claims/emailaddress",
                                                    StringComparison.OrdinalIgnoreCase));
Email = emailClaim == null ? null : emailClaim.Value;
