I am trying to create a Firebird connection in Visual Studio 2015. I have a C # class library with which I would like to connect to the Firebird database. I installed these plugins from NuGet:

But when I try to add a new “ADO.NET Entity Data Model” element with “EF Designer from the database”, the Firebird connection is not listed:

Reading articles on the Internet showed that an entry in the machine.config file should be made. But that did not happen. There is no Firebird entry in this configuration file.
The link "FirebirdSql.Data.FirebirdClient" exists in the Visual Studio project.
Entry in the App.config file:
<DbProviderFactories>
<remove invariant="FirebirdSql.Data.FirebirdClient" />
<add name="FirebirdClient Data Provider" invariant="FirebirdSql.Data.FirebirdClient" description=".NET Framework Data Provider for Firebird" type="FirebirdSql.Data.FirebirdClient.FirebirdClientFactory, FirebirdSql.Data.FirebirdClient" />
</DbProviderFactories>

- ? Firebird?
