Instructions

By default PostgreSql installed on 5432 port. If you have already configured the port while installing pgAdmin, then try to mention the port number under port key in connection string , then only you can able to do database operations.In the other case without the port number also works fine.

Npgsql is a dll can be downloaded from *"Manage NuGet Packages"
