How to open Visual Studio Solution File from the Command Prompt

If you haven't done cd MySolution but are still in the directory from which you did the git clone just type

start MySolution/MySolution.sln and hit Enter.

This will open whatever version of Visual Studio you currently have set to open with .sln files in Windows.

If you don't mind using PowerShell, you should try WhatsNew. Once installed, you can just type sln to open the solution file in that directory.
