Missing PostgreSQL data provider in Visual Studio 2010

Question

I'd like to continue from my previous question SQLite database file type missing from Visual Studio 2010 data source options

I want to crete a connection to PostgeSQL database this time and facing the same issue about a missing data source.

So far I have:

1. Installed the PostgreSQL server and a new database created
2. Under Visual Studio 2010, inside PMC, I run "Install-Package Npgsql"
3. In the app.config file I registered the Npgsql Data Provider by adding the DbProviderFactories block

Then, I try to create ADO.NET Entity Data Model from Visual Studio by generating it from the database (using Entity Framework 4). I'm trying to make a connection to the PostgreSQL database but I don't see how to connect to it. Below what I have:

How do I make a connection to PostgreSQL database?
