无法升级或降级NuGet包

我有一个ASP.NET核心网站,它依赖于2个类库。

他们都引用了Microsoft.NETCore,但版本已经混淆了,并引导我收到警告:

  

检测到的软件包降级:Microsoft.NETCore.App从1.1.0升级到1.0.3

NuGet不会让我更改Microsoft.NetCore.App的版本:

Cant update package

如果我尝试升级或降级,我会收到错误

  

由于项目中的其他限制或packages.config

,以下版本不可用

如何解决此错误?

我的csproj文件:

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

  <PropertyGroup>
    <TargetFramework>netcoreapp1.0</TargetFramework>

修改

以下是我的类库的参考:

数据访问层:

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

  <PropertyGroup>
    <TargetFramework>netcoreapp1.0</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="AutoMapper" Version="5.2.0" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.InMemory" Version="1.1.0" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="1.1.0" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.Tools" Version="1.1.0-msbuild3-final" />
  </ItemGroup>

</Project>

数据传输对象:

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

  <PropertyGroup>
    <TargetFramework>netcoreapp1.0</TargetFramework>
  </PropertyGroup>

</Project>

答案 0 :(得分:7)

即使在一个全新的空ASP.NET核心项目中,似乎也会出现“由于其他约束而导致以下版本不可用”的消息。我认为这是一个bug或NuGet GUI的一个功能。 (我正在使用Visual Studio 2017的最终版本)

您可以通过直接编辑.csproj文件来解决此问题:在解决方案资源管理器中右键单击项目,然后选择编辑(项目名称).csproj

您可以在第一个PropertyGroup中提升Microsoft.NETCore.App(和目标框架)的版本:

<PropertyGroup>
  <TargetFramework>netcoreapp1.1</TargetFramework>

  <!-- snip -->

  <RuntimeFrameworkVersion>1.1.0</RuntimeFrameworkVersion>

  <!-- snip -->
</PropertyGroup>

然后,关闭文件并重建项目。我使用您在问题中提到的所有(公共)依赖项对此进行了测试,但未发现任何包版本冲突。
