ASP.NET MVC Views
ASP.NET Boilerplate is integrated to MVC Views via Abp.Web.Mvc nuget package. You can create regular MVC Views as you always do.
AbpWebViewPage Base Class
ASP.NET Boilerplate also provides AbpWebViewPage, which defines some useful properties and methods. If you created your project using startup templates then all your views are automatically inherited from this base class.
