【问题描述】:
我正在尝试更新到 NET Core 2.0,但我在使用该参考安装的所有包上都遇到了这些错误。
问题可能是:
我在输出中获得了对 netcoreapp1.0 的引用:
Microsoft.EntityFrameworkCore.Tools.DotNet 2.0.0 包与 netcoreapp1.0(.NETCoreApp,版本 = v1.0)不兼容。 Microsoft.EntityFrameworkCore.Tools.DotNet 2.0。 0 包支持:netcoreapp2.0(.NETCoreApp,版本 = v2.0) 一个或多个包与 .NETCoreApp 不兼容,版本 = v1.0。 检测到的包检测:Microsoft.ApplicationInsights.AspNetCore 从 2.1.1 到 2.0.0 Microsoft.AspNetCore.All (> = 2.0.0) -> Microsoft.AspNetCore.ApplicationInsights.HostingStartup (> = 2.0.0) -> Microsoft.ApplicationInsights.AspNetCore (> = 2.1.1) 应用程序 (> = 1.0.0) -> Microsoft.ApplicationInsights.AspNetCore (> = 2.0.0)
之后,我收到所有组件的这条消息:
Microsoft.AspNetCore.ANYPACKAGE 2.0.0 包与 netcoreapp2.0(.NETCoreApp,版本 = v2.0)不兼容。 Microsoft.AspNetCore.WebSockets 2.0.0 包支持:netstandard2.0 (.NETStandard, Version = v2.0)
这是手册:

SDK 更新到 2.0:
这是我的csproj:
