Answer 1

Filters are supported in ASP.NET Core MVC. You can find them in Microsoft.AspNetCore.Mvc.Filters namespace. Take a look at this guide for example.

Bear in mind that you don't need to implement JWT authentication filter yourself. This has already been implemented as part of Microsoft.AspNetCore.Authentication.JwtBearer NuGet package. All you need is to use a JwtBearerAuthentication middleware in your app by adding app.UseJwtBearerAuthentication(new JwtBearerOptions { /* options */ }) to Startup.Configure() method.
