Firebird + Entityframework - Problem to add connection

Question

I’m having trouble adding a Firebird connection to Visual Studio

I followed every step of the documentation

1. I installed Firebirdsql.Data.Firebirdclient
2. gacutil / i Firebirdsql.Data.Firebirdclient.dll
3. gacutil / i Entityframework.Firebird.dll
4. edited and executed the registry file for VS2015
5. edited the machine.config

After that Firebird was added to the data source choice form

But when I advance to the configuration, the form you open is not like the one in the documentation: https://firebirdsql.org/file/documentation/reference_manuals/fbdevgd-en/html/fbdg30-efw-vs-prepare.html#efw-database-locate

VS opens this form

So I tended to inform a connection string, but it generates this error.

I get the impression that VS is loading a standard form.
