In this question, it is discussed the difference between platform targeting in Visual Studio, I recently found that a .NET option was added there and these lines along others were added in the sln file.
Debug|.NET = Debug|.NET <---- Added
Debug|Any CPU = Debug|Any CPU
Debug|Mixed Platforms = Debug|Mixed Platforms
Debug|x86 = Debug|x86
Release|.NET = Release|.NET <---- Added
Release|Any CPU = Release|Any CPU
Release|Mixed Platforms = Release|Mixed Platforms
Release|x86 = Release|x86
These options are being added to each project in each solution I am opening recently. I thought these options target a particular CPU architecture, AFAIK .NET is not one so what does its presence means?
