@AlekseyTs That looks like #35300 which we fixed recently and not related to nullability. Which VS version are you using?

AlekseyTs commented 5 years ago

VisualStudio.16.IntPreview/16.2.0-pre.2.0+28921.361.d16.2stg

It worked once I disabled the checkbox in the properties. Feels like there is some correlation.
