@maraf please look again, I made few more changes

[maraf]

This change doesn't help us anyway, right?
Should we revert it and make in the build incrementalism tracking issue?

[maraf]

Suggested change

	<GenerateRuntimeConfigurationFiles Condition="'$(GenerateRuntimeConfigurationFiles)' == '' and '$(_TargetingNETBefore100)' == 'true'">false</GenerateRuntimeConfigurationFiles>
	<GenerateRuntimeConfigurationFiles Condition="''$(_TargetingNETBefore100)' == 'true'">false</GenerateRuntimeConfigurationFiles>

I think we should maintain the behavior from previous SDK when targeting downlevel versions
