Answer 1

Enabling and starting the SQL Browser service fixed the problem for me. That avoids messing around with IP addresses and TCP ports.

Integrated security would not work, however, I had to revert to SQL User ID and password.

I changed the connection string to use TCP/IP

Before

Data Source=xpt/SqlServerExpress;Initial Catalog=gestao_eficaz;User ID=sa;Password=somePassword

After

Data Source=127.0.0.1,1433;Initial Catalog=gestao_eficaz;User ID=sa;Password=somePassword

It is also necessary to enable the TCP / IP connection in the sql server
