Can you check if [http://localhost:62114/Account/TestNotification]) works?
It says right there:
ArgumentException: Type CitiXsys.iVend365.EntityFrameworkCore.Repositories.iVend365RepositoryBase`1[[Abp.Localization.ApplicationLanguage, Abp.Zero.Common, Version=3.0.0.0, Culture=neutral, PublicKeyToken=null]] does not have a public default constructor and could not be instantiated.
You need to provide a public default constructor.

Update to VS2017 15.3.3+. For VS2015, install NETStandard.Library.NETFramework package.
Yes, it's possible.
See:
Check that you added AutoRepositoryTypes attribute to your DbContext (see docs).
Unfortunately, this is not allowed in ABP framework. I suggest setting email address to be username in your case.
Do you mean create your own error notification?
abp.message.error("User not signed in");
Does reverting it to public work?
