Done.

Mysql is on MacOs and Visual Studio is also on MacOs. On my own, I could not understand, maybe someone knows, thanks in advance.

Good afternoon.
You wrote an error quite in English:
Unrecognized configuration section (/Users/habcerga1/Desktop/Projects/Demo6/Demo6/bin/Debug/Demo6.exe.config line 11)
So check line 11 in /Users/habcerga1/Desktop/Projects /Demo6/Demo6/bin/Debug/Demo6.exe.config
file
MySql client initializer when parsing your config file does not understand what is written there
