Microsoft announced the availability of .NET Standard 2.0 support for UWP development

Microsoft announced a great update for .NET developers for UWP, the biggest improvement being the addition of support for .NET Standard 2.0. UWP developers can now access about 20k APIs. UWP will be consistent with other .NET implementations that support .NET Standard 2.0.
