F#, VSCode and OSX: The namespace or module 'Expecto' is not defined

Question

I am attempting to get started with F Sharp.

I have mono installed via brew and dotnetcore installed via d/l.

I have VS Code and the ionide plugin installed.

I have done the following steps:

• project > new > expecto
• paket install
• fake build
• expecto run

Install appears to occur with no errors. Build directory is empty after the fake build task. Expecto run does ... nothing.

When I open the generated Main.fs file, the editor tells me:

The namespace or module 'Expecto' is not defined

Is there something I am missing?

Answer 1

For future reference the fix if you are staying with the Ionide generated defaults is to make sure your target framework is set to .net core and not .net framework

<TargetFramework>netcoreapp2.0</TargetFramework>
