ASP.NETCORE安装/更新包时出现兼容性错误

我有一个ASP.NETCORE web应用程序，我正在尝试使用visual studio在其上安装SendGrid软件包，但它给我一个错误，说明一个或多个软件包与.NETCoreAPP，Version=v1.1不兼容。 然后我注意到当前的软件包有可用的更新，我尝试更新当前的软件包，但它仍然给我相同的错误

这是错误消息：

Package Microsoft.Composition 1.0.27 is not compatible with netcoreapp1.1 
(.NETCoreApp,Version=v1.1). Package Microsoft.Composition 1.0.27 supports: 
portable-net45+win8+wp8+wpa81 (.NETPortable,Version=v0.0,Profile=Profile259)
One or more packages are incompatible with .NETCoreApp,Version=v1.1.

这是我的project.json文件：

"dependencies": {

    "type": "default",

我对这一点非常陌生，对一般编程也很陌生。如果您需要查看项目中的更多文件，请告诉我。
