+All the validations below should be performed on both Windows and at least one Unix platform (MacOS, Linux).  These can be done on x64 versions unless there are ARM specific changes to validate.
 
 #### Opening projects
 When you open a directory in VS Code, the C# extension should look for a .csproj, .sln, or .slnf file in that directory and use "OmniSharp" to load it. If a .cs file is present and no .csproj, .sln, or .slnf file are present, Omnisharp should start but the intellisense should only appear when a change is made to the file.
