* Disable strict compliance on tests project to work around a VS2017 compiler bug: https://developercommunity.visualstudio.com/content/problem/288560/cppunittestassert-doesnt-compile-with-permissive-i.html * Disabling /permissive- for all build flavors * Add ESRP delay signing key * Add Microsoft prefix per MSFT requirements * Sign.cmd is no longer needed * Update assembly namespace to match nuget id * Fix nuget file references * Update expected public key * Bump nuget version to 2.0.0
