VS Code C# script on Ubuntu cannot find OpalKelly

Hello,

I’m have a fully working C# script in Windows using Visual Studio interfacing with Opal Kelly XEM7310.

I am aiming to port this script over to a Linux machine. I have downloaded and installed FrontPanel for Ubuntu 22.04. But when I run the script in VS Code, I get the following error messages:

The type or namespace name ‘OpalKelly’ could not be found (are you missing a using directive or an assembly reference?)

The type or namespace name ‘okCFrontPanel’ could not be found (are you missing a using directive or an assembly reference?)

This is what my code implements:

using OpalKelly.FrontPanel;

public okCFrontPanel dev;

dev = new okCFrontPanel();

Looking online, I tried adding a reference to FrontPanel to my .csproj file, but it did not make any difference:

<Reference Include="libokFrontPanel">
<SpecificVersion>False/SpecificVersion>
<HintPath>.\libokFrontPanel.so</HintPath>
</Reference>
</ItemGroup>

It seems that the VS Code environment is not picking up the FrontPanel library files.
Any help would be much appreciated.
Thanks,
-Phil.
