将.NET Core项目从v1.0升级到v1.1并面临以下错误

Question

我将我的.NET Core项目从v1.0升级到v1.1并面临以下错误

包Microsoft.Net.Http 2.2.29与netcoreapp1.1（.NETCoreApp，Version = v1.1）不兼容。

包Microsoft.Bcl 1.1.10与netcoreapp1.1（.NETCoreApp，Version = v1.1）/ win10-x64

不兼容

解决方案中的所有项目都在编译并说“重建成功”＃34;但是这些错误仍然出现在＆＃34;错误列表＆＃34;。

中

我正在使用Visual Studio 2017。

有修复吗？请指教。

检查您的输出，我刚尝试将Microsoft.Net.Http安装到我的NetCore1.1项目中并获得相同的结果。读取nuget安装的输出我看到了：

如您所见，此软件包尚不支持.Net Core或.Net Standard。此外，Microsoft.Bcl依赖关系来自Microsoft.Net.Http，同样不支持.Net Standard / Core

最好的办法是切换到支持.Net Standard和.Net Core的System.Net.Http
