c# - How to extend Identity in Net Core Web API -

hi i'm using entityframework core , want use built in identity authentication net core web api, why did following:

-create class extends identityuser, , add custom properties :

public class myuser : identityuser {         public myuser(string username) : base (username) { }         public string firstname { set; get; }         public string lastname { set; get; }         public datetime birthdate { set; get; } } 

create db context class inherits identitydbcontext :

public class dbcontext : identitydbcontext<myuser> {         public dbcontext (dbcontextoptions<dbcontext> options) : base (options) { }         public dbset<story> stories { set; get; }         protected override void onmodelcreating (modelbuilder builder) {             base.onmodelcreating (builder);         } } 

then registered custom class , db context in startup.cs(in configureservices method):

public void configureservices (iservicecollection services) {             var connection = @"server=(localdb)\mssqllocaldb;database=dbef;trusted_connection=true;";              services.adddbcontext<dbcontext> (options => options.usesqlserver (connection,                 optionsbuilder => optionsbuilder.migrationsassembly ("webapiefcore")));              services.addidentity<myuser, identityrole> ()                 .addentityframeworkstores<dbcontext> ()                 .adddefaulttokenproviders ();              services.configure<identityoptions> (o => {                 o.signin.requireconfirmedemail = true;             });              services.addmvc (); } 

finally enabled migrations , update db can see here:

the db identity tables plus custom 1 created.

looking on internet found version of identity using asp.net web api, seems need override method in custom user class, properties of class saved.

i followed tutorial implement identity in web api, of tutorials use identity mvc not pure web api: tutorial followed

my question is:

how create controller post action can register users. , need modify in custom user class can save custom properties in db.

also when register user has have properties class: firstname, lastname , birthday. meant cannot null , have filled, if empty cannot save db.

thanks

have @ samples in their github repository:

for instance post in controller, can @ register method (the method you're looking createasync method on usermanager object)
