dotnet core 出现Can not find runtime target for framework '.NETCoreApp,Version=v1.6' 的解决办法

如果你在更新dotnet core新的类库后运行程序提示如下的错误：

Can not find runtime target for framework '.NETCoreAPP, Version=v1.0' compatible with one of the target runtimes: 'win10-x64, win81-x64, win8-x64, win7-x64'. Possible causes:
        The project has not been restored or restore failed -run 'dotnet restore'
        The project does not list one of 'win10-x64, win81-x64, win7-x64' in the 'runtimes'

解决方法：在项目的 project.json 文件添加以下的节点 重新编译即可:

"runtimes":{
"win10-x64":{}
}
或者 可以修改Microsoft.NETCore.App节点的内容如下，Version的版本请对应你的dotnet core版本号
"Microsoft.NETCore.App":{
"type":"platform",

"version":"1.0.1"

}
