Asp.net core 将.NET核心重新定位为net471、Net472

My.Netcore 2.0项目可以针对

net471

。 但是当我升级到.NET2.1时，我无法重新定位

net471

或

net472

我可以在最新版本的.NET core中重新定位目标吗

Severity Code Description Project File Line Suppression State
Error NU1202 Package Microsoft.AspNetCore.App 2.1.0 is not compatible with net471 (.NETFramework,Version=v4.7.1). Package Microsoft.AspNetCore.App 2.1.0 supports: netcoreapp2.1 (.NETCoreApp,Version=v2.1) 

及

---

它看起来像是

Microsoft.AspNetCore.App

和

Microsoft.AspNetCore。所有
软件包都只能使用
netcoreapp2.0
或
netcoreapp2.1
版本

要以.NET Framework为目标，即
net471、net472
，必须删除这些包并手动添加引用

在我的例子中，我删除了
Microsoft.AspNetCore.App
，并添加了如下引用

<PackageReference Include="Microsoft.AspNetCore" Version="2.1.1" />
<PackageReference Include="Microsoft.AspNetCore.Hosting.WindowsServices" Version="2.1.1" />
<PackageReference Include="Microsoft.AspNetCore.Mvc" Version="2.1.1" />
<PackageReference Include="Microsoft.AspNetCore.StaticFiles" Version="2.1.1" />
<PackageReference Include="Microsoft.Extensions.Logging.Debug" Version="2.1.1" />
<PackageReference Include="Microsoft.Extensions.Logging.EventLog" Version="2.1.1" />
<PackageReference Include="Microsoft.Extensions.Options" Version="2.1.1" />

洪奎奇的答案是正确的，99%正确。但是我发现它少了两个包裹。下面是完整的.csproj，包括两个缺少的项目参考：

<Project Sdk="Microsoft.NET.Sdk.Web">

  <PropertyGroup>
    <TargetFramework>net472</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore" Version="2.1.1" />
    <PackageReference Include="Microsoft.AspNetCore.CookiePolicy" Version="2.1.1" />
    <PackageReference Include="Microsoft.AspNetCore.Hosting.WindowsServices" Version="2.1.1" />
    <PackageReference Include="Microsoft.AspNetCore.HttpsPolicy" Version="2.1.1" />
    <PackageReference Include="Microsoft.AspNetCore.Mvc" Version="2.1.1" />
    <PackageReference Include="Microsoft.AspNetCore.StaticFiles" Version="2.1.1" />
    <PackageReference Include="Microsoft.Extensions.Logging.Debug" Version="2.1.1" />
    <PackageReference Include="Microsoft.Extensions.Logging.EventLog" Version="2.1.1" />
    <PackageReference Include="Microsoft.Extensions.Options" Version="2.1.1" />
    <PackageReference Include="Microsoft.AspNetCore.Razor.Design" Version="2.1.2" PrivateAssets="All" />
  </ItemGroup>

</Project>


网络472
在大多数情况下，这是因为.NET Core SDK或Nuget的版本已经过时。因此，尝试更新NugetMicrosoft.AspNetCore.App的版本是新版本，随附Asp.net core 2.1消息内容
AspNetCore.App
是一个针对.NETCore2.1的元包。它的使用使我们不必引用几十个较小的ASP.NET核心程序集。如果您想重新定位到.NET Framework，您必须删除
AspNetCore.App
并添加所需的单个软件包，即
Microsoft.AspNetCore.Mvc
最简单的方法是，创建一个新的空ASP.NET Core项目，以.NET Framework 4.7.2为目标，然后从中复制包引用，并用这些引用替换
.AspNetCore.All
（或
.AspNetCore.All
）包，以及更改CSProjTanks中的目标平台，@Tseng您的解决方案工作正常。
