更新到 ASP.NET Core 2.0 包与 netcoreapp2.0 不兼容

我正在try 更新到Net Core2.0，但在随参考一起安装的所有包上都出现了这些错误.

The problem, maybe:

我在输出中得到了对netcoreapp1.0的引用:

The Microsoft.EntityFrameworkCore.Tools.DotNet 2.0.0 package is not compatible with netcoreapp1.0 (.NETCoreApp, Version = v1.0). The Microsoft.EntityFrameworkCore.Tools.DotNet 2.0.0 package supports: netcoreapp2.0 (.NETCoreApp, Version = v2.0) One or more packages are not compatible with .NETCoreApp, Version = v1.0. Detection of detected package: Microsoft.ApplicationInsights.AspNetCore from 2.1.1 to 2.0.0   Microsoft.AspNetCore.All (> = 2.0.0) -> Microsoft.AspNetCore.ApplicationInsights.HostingStartup (> = 2.0.0) -> Microsoft.ApplicationInsights.AspNetCore (> = 2.1. 1)   Application (> = 1.0.0) -> Microsoft.ApplicationInsights.AspNetCore (> = 2.0.0)

之后，我收到所有组件的信息:

微软.AspNetCore.ANYPACKAGE 2.0.0软件包与netcoreapp2不兼容.0(.NETCoreApp，版本=v2.0).微软.AspNetCore.WebSockets 2.0.0包支持:netstandard2.0(.NETStandard，Version=v2.0)

这是手册:

SDK更新至2.0:
