Can not enable VSCode Intellisense when working with Unity C# project

• If you use unity project gitignore template, remember to remove .sln from gitignore, otherwise VSCode couldn't fetch project setting thus no Intellisense enabled.

Install venv in WSL

If you install in Windowns part (/mnt/XXX), an error will occur. Error: Command '['/mnt/e/joseph/code/python/venv2/bin/python3', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1.

Switch to Linux part by cd and python3 -m venv venv again should fix the problem
