我正在尝试升级到.NET Core 2.0,但是在所有已安装引用的包上都遇到了这些错误。
可能的问题:
输出中出现了对netcoreapp1.0
的引用:
Microsoft.EntityFrameworkCore.Tools.DotNet 2.0.0包不兼容netcoreapp1.0 (.NETCoreApp, Version = v1.0)。 Microsoft.EntityFrameworkCore.Tools.DotNet 2.0.0支持:netcoreapp2.0 (.NETCoreApp,Version = v2.0) 一个或多个包与.NETCoreApp,Version = v1.0不兼容。 检测到的包:从2.1.1的Microsoft.ApplicationInsights.AspNetCore到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,我收到了所有组件的此消息:
Microsoft.AspNetCore.ANYPACKAGE 2.0.0包不兼容netcoreapp2.0 (.NETCoreApp, Version = v2.0)。Microsoft.AspNetCore.WebSockets 2.0.0包支持:netstandard2.0 (.NETStandard,Version = v2.0)
这是手册:
