I've installed the followings
- PowerBI desktop
- PostgreSQL
- Npgsql v4.1.1 (from https://github.com/npgsql/Npgsql/releases)
- Visual Studio 2019 (community)
Even after installing all the above, still I am getting
This connector requires one or more additional components to be installed before it can be used.
Is there anything else, I've to install?
