I'm developing an NF-e Web Generator. In the action for the generation of NF-e, I need to request the client's digital certificate through the browser, which can be either A1 or A3, just like the e-Cac website does:
Where this site submits to: link
How can I call this certificate screen with ASP.NET MVC C #? And how do I treat it in server action?
I've researched a lot of places, and so far I have not found anything that works.
