Description
Is your feature request related to a problem? Please describe
System.Windows.Forms.Design does not have <Nullable>enable</Nullable> in its project file and the individual files aren't marked to enable/disable NRTs.
I am creating this issue to help track the progress
I suggest the following plan which has been implemented previously with other projects:
- Enable Nullable in the project file and marking each file with
#nullable disablewhere needed. - Community/team PRs to slowly enable nullability in the code base.
Related: #1107
List of files which need annotating ordered by line count ascending:
