What changes will be made to. NET Core 2.0 and. NET Standard 2.0.

To reduce the barriers to entry and learning,. NET Standard 2.0 can easily share code across. NET Framework,. NET Core, and Xamarin through standardized sharing APIs.

. NET Standard 2.0 adds a number of Apis supported by. NET Framework 4.6.1 and APIs unique to. NET Standard 2.0.

• . NET Standard 2.0 added 14,994. NET Framework 4.6.1 supported APIs
• . NET Standard 2.0 only 43 APIs not supported by. NET Framework 4.6.1

. NET Standard 2.0 is a superset of. NET Standard 1.6. In other words,. NET Standard 2.0 and 1.x will not undergo any breakthrough changes.
. NET Framework 4.6.1 will allow reference of binary files compiled according to. NET Standard 2.0.

It can be understood that. NET Core 2.0 is equivalent to. NET Framework 4.6.1.
