Building my own custom storage provider for identity core. Could someone please tell me the necessary storages to implement?
So far, I have implemented UserStore methods. Is it necessary to also implement RoleStore in order to use SignInManager? Because SignInManager.PasswordSigningAsync is throwing null object exception.

2021-02-05T07:11:58.433+00:00 Hi @Yinqiu Yao-MSFT I am using ASPNETCore.Identity SignInManager, but I have written custom UserStore by inheriting IUserStore of ASPNETCore.Identity in order to do DB related transactions for identity.

2021-02-05T07:23:56.83+00:00 Hi @Manjunath MR ,I think the reason for your SignInManager.PasswordSignInAsync throwing null object exception is the null attribute in ApplicationUser. This happens when you create custom claims in ApplicationUser. The generated UserIdentity will contain your custom claims, where Any empty object will raise this exception.

2021-02-05T07:30:05.903+00:00 Thank you so much for your response @Yinqiu Yao-MSFT . Is it compulsory to implement IRoleStore? in order to use ASPNETCore.Identity.SignInManager and I have also not implemented any IUSerClaims related methods as well.

2021-02-06T00:45:52.757+00:00 Hi @Manjunath MR ,Yes, the default ASPNETCore.Identity.SignInManage contains many functions, you can view its source code, you can customize SignInManager according to the functions you want to achieve instead of using the default ASPNETCore.Identity.SignInManage, if your SignInManager needs Role-related functions, then you need to implement it.
