升级到 NetCore 3.1 后找不到版本 (= 2.2.7) 的软件包 Microsoft.NETCore.App.Host.win-x64

Question

I update nuget packages from 2.2.x to 3.1.0 on my local feed. Then, out build machine try to build projects, but:

Project.csproj(0,0): Error NU1102: Unable to find package Microsoft.NETCore.App.Host.win-x64 with version (= 2.2.7)
- Found 1 version(s) in localfeed [ Nearest version: 3.1.0 ]

nuget.org link says that i should not use it directly. So i am not using it directry.

Example of csproj:

  <Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup Label="Globals">
 <SccProjectName>SAK</SccProjectName>
 <SccProvider>SAK</SccProvider>
 <SccAuxPath>SAK</SccAuxPath>
 <SccLocalPath>SAK</SccLocalPath>
 </PropertyGroup>

  <PropertyGroup>
<ProjectGuid>{9B42C5B4-188E-482F-BC44-C3B243F92848}</ProjectGuid>
<OutputType>Exe</OutputType>
<TargetFrameworks>netcoreapp3.1</TargetFrameworks>
<PackageId>Project</PackageId>   
<AssemblyName>Projectr</AssemblyName>
<Version>1.1.0</Version>

Why .net core can not use Microsoft.NETCore.App.Host.win-x64 3.1.0 version?

Answer 1

In .csproj file of our application we have RuntimeFrameworkVersion. There we update it to desired version :

<PropertyGroup>
    <TargetFramework>netcoreapp3.1</TargetFramework>
    <RuntimeFrameworkVersion>3.1.0</RuntimeFrameworkVersion>
</PropertyGroup>

Answer 2

Problem was on msbuild config of this build task (targeting build task on 2.2.7). changing on 3.1.0 solve problem

Answer 3

将visual studio更新到最新版本对我有用:-)
