Hi venkyy

  SSRS report is an ASP.NET Web Forms control. You need something you can integrate into your ASP.NET Core/MVC app or non-ASP.NET app.However Microsoft is not implementing or bringing RDLC report viewer into aspnet core. Instead they are purchasing a product to fill the void. Here is the link ,I hope it will help you.
