Description Geoff Armstrong 2015-08-08 15:51:31 UTC
Sample code:

var x = ""?.Length;

Hover mouse over x, you'll see it inferred as "int" not "int?" and if you do x.| (where the vertical bar is the cursor) you'll notice you get help for an int, not a nullable int.

Basically, ?. with a struct member produces a nullable struct, not a struct.

Will work in 6.0.
