@layomia this "user story" needs to be assigned to an engineering owner -- I'm guessing you? need not be the person who will actually do it, but the person that is responsible at the moment.

[layomia]

Yup I'll assign myself and work with @steveharter to get these in.

[danmoseley]

@layomia can we move this to "complete" (on the project board) and close it now?

For those observing: the although the "dynamic" keyword part here was done, we have removed it for 6.0: dotnet/docs#25105

[layomia]

@danmoseley yes we can.
