VSCode setup for intellisense for space engineers programmable blocks.
I am using this on Linux. Based of https://github.com/gregretkowski/VSC-SE
Download the contents of the repo.
You will need dotnet installed (version 6.0 tmk) and C# vscode extensions active.
In SE/SpaceEngineers.csproj replace /storage/SteamLibrary/steamapps/common/SpaceEngineers with your se install folder.
Run dotnet build, it might error so try it again and see if the errors go away.
Open SE/template.cs, see if it has IntelliSense, if not, restart VSCode.
