.NET Core 2.0的发布时间，.NET Core 2.0预览版及.NET Standard 2.0 Preview大概在5月中旬或下旬发布。

.NET Core 2.0正式版本发布时间大约在Q3 2017发布，具体我估计大概在8月份左右。同时一起发布的也就是.NET Standard 2.0。

微软计划在5月10日将corefx 中标记为2.0 的bug 完全修复。使其顺利发布 .NET Core 2.0 Preview 和 .NET Standard 2.0 Preview 。

以下为具体链接： [Announcement: Driving towards zero 2.0 bugs by 2017/5/10 (ZBB)][Announcement_ Driving towards zero 2.0 bugs by_2017_5_10_ZBB]  ZBB (zero bug bounce)。

大家也可以参与其中，贡献自己的一份力量。

.NET Core 2.0版最低操作系统支持

S 为得到三星支持

C 为得到社区支持

那么.NET Core 2.0 及 .NET Standard 2.0 将会带来哪些改变。

降低入门及学习的障碍，.NET Standard 2.0通过标准化共享API，可以轻松地跨.NET Framework，.NET Core和Xamarin共享代码。

.NET Framework 4.6.1支持.NET Standard 2.0

.NET Standard 2.0 添加了许多.NET Framework 4.6.1 支持的API，以及.NET Standard 2.0  自己特有的API

*  .NET Standard 2.0 添加了 14,994 个.NET Framework 4.6.1已经支持的API 
 *  .NET Standard 2.0 只有 43 个 .NET Framework 4.6.1不支持的API

.NET Standard 2.0 将是.NET Standard 1.6的超集。 换句话说，.NET Standard 2.0和1.x不会发生突破性的变化。  
.NET Framework 4.6.1将允许引用根据.NET Standard 2.0编译的二进制文件。

最终可以理解为.NET Core 2.0 将是等价于 .NET Framework 4.6.1。

.NET Standard 2.0 工作正在进行中

.NET Standard

![443844-20170410152242751-71486256.png][]

对于开发人员来说，这意味着他们只需要掌握一个基类库。该库面向.NET Standard 将能够在所有.NET平台上运行。

.NET Standard 的核心使命在于解决 .NET 跨平台时基础链接库不一致的问题。
