timer.Stop();

This is the output:
Connecting...
Exception happened: Method not found: 'LanguageExt.Option`1 GF.Net.IProtoClient`2.get_Host()'.


can anyone help me understand the issue?

We do not support .core. The package is not fully compatible with Net 8, ' Package GFAPI 4.11.519.358 was restored using v4.6.2/7/7.1 instead of the taget net8.0'

Using a ConsoleApp (.Net Framework) instead of .Net Core, fixes this issue and it is compatible with the GFAPI nuGet package 4.6.2

When run with .Net 4.8 the program ran fine.
