eebcc20f - Add netstandard2.0 framework to nuget managed package. (#8960)

Add netstandard2.0 framework to nuget managed package. (#8960) * Add netstandard2.0 to nuget managed package. Re-does PR that was backed out due to packaging pipeline changes. Allows deprecation of netstandard1.1 in the following release as netstandard2 is the preferred lowest level framework.
