To resolve this issue, make sure the same settings are used for restore and for subsequent operations such as build or publish.  Typically this issue can occur if the RuntimeIdentifier property is set during build or publish but not during restore.

@muratg can we get this for RTM? Our release/2.1 branch tests are failing 100% of the time.

@Tratcher can you take a look please? Any test fix is approved for this week.
