I have a visual studio package which currently targets .NET Framework version 4.5 and works with Visual Studio versions from 2012 up to 2019.
If I upgrade to .NET Framework 4.7.2, what does this mean for compatibility with different versions of Visual Studio?
Will it automatically make the package incompatible with older versions of Visual Studio (e.g. 2012, 2013 and 2015)?
if you install a specific version of .net framework you can see that in your target framework. you can use this address to see all the .net SDK for visual studio
