Not sure what exactly you mean, but when I type a dot, I see all the properties and methods in a listbox in an editor window.
This will probably not be the case in the Terminal screen (depending how and which session you run in there).Blog: http://lucd.info | Twitter: @LucD22 | PowerCLI Reference co-author: http://tinyurl.com/hkn4glz
Usually when I see that there is some error somwhere else. Generally if I try and run the current script, then try again it works.
In the ISE the Terminal window is driven by the Windows PowerShell ISE Host.
That feature is builtin into that Host, but not in the ConsoleHost nor in the Visual Studio Code Host afaik.
You can always raise an Issue in the PowerShell Language Support for Visual Studio Code repo.Blog: http://lucd.info | Twitter: @LucD22 | PowerCLI Reference co-author: http://tinyurl.com/hkn4glz
