docker dotnet Restore 的时候报错, 一度怀疑是linux的dotnet core sdk没有装好,
卸了装, 装了卸, 试了好几遍还是无效(Microsoft.Common.CurrentVersion.targets 这个文件的确又是存在的),
找度娘也没找到解决方案,
/usr/share/dotnet/sdk/2.1.801/Microsoft.Common.CurrentVersion.targets(2106,5): warning MSB3245: Could not resolve this reference. Could not locate the assembly "System.ComponentModel.Annotations". Check to make sure the assembly exists on disk. If this reference is required by your code, you may get compilation errors. [xxxxxxx.csproj]
