I have migrated code from vs2010,.net framework 4.0 to vs2019 ,.net framework 4.8. After the change tool version got changed from 4.0 to 12.0 in .csproj file.
I understand that vs2010 uses tool version 4.0 ,vs2013 uses 12.0 and vs2019 uses current.
So after migration it should change to current why it has changed to 12.0 version.
I manually changes the version to cuurent and there were no build issues.
So should i keep the 12.0 too version or manually changed current version
