我收到错误消息"Microsoft.AspNetCore.Hosting.Abstractions，Version = 3.1.0.0"..NET Core 3.1应用程序中 [英] I'm getting the error "Microsoft.AspNetCore.Hosting.Abstractions, Version=3.1.0.0" in .NET Core 3.1 app

问题描述

最新版本的"Microsoft.AspNetCore.Hosting.Abstractions"是2.2.0，所以我不确定它从哪里获得3.1.0.0.

The latest version of "Microsoft.AspNetCore.Hosting.Abstractions" is 2.2.0, so I'm not sure where it's getting 3.1.0.0.

我已经浏览了所有.csproj文件，并且所有文件都引用了2.2.0.我不确定还有什么地方可以找到.

I've gone through all of my .csproj files, and all of them are referencing 2.2.0. I'm not sure where else to look.

我有3个不同的应用程序(解决方案)共享项目，并且这都是在不同时间发生的.如果我从VS中发布它们，则其中一个可行，但我想尝试使用Azure DevOps发布管道进行部署.

I have 3 different applications (solutions) that share projects, and this is happening on all of them at different times. One of them works if I publish it from VS, but I'd like to try to get them deployed using Azure DevOps release pipeline.

推荐答案

Nuget包 Microsoft.AspNetCore.Hosting.Abstractions 已移至

The Nuget package Microsoft.AspNetCore.Hosting.Abstractions has moved to Microsoft.Extensions.Hosting.Abstractions for versions 2.x and above, all 3.x versions are there, as well as 5.x versions. the 2.x version is most likely left in the old nuget package as a compatibility package or similar.
