我有一个ASP.NET Core网站,它依赖于2个类库。

他们都引用了Microsoft.NETCore,但是这些版本有些混淆,导致我收到警告:


检测到的程序包降级:Microsoft.NETCore.App从1.1.0降到1.0.3


NuGet不允许我更改Microsoft.NetCore.App的版本:

asp.net-core - 无法升级或降级NuGet软件包-LMLPHP

如果我尝试升级或降级,则会收到错误消息


由于项目或packages.config中的其他限制,以下版本不可用


我该如何解决这个错误?

我的csproj文件:

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

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

编辑:

这是我的类库的参考:

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>

最佳答案

即使在全新的空ASP.NET Core项目中,似乎也会出现“由于其他限制而导致以下版本不可用”的消息。我认为这是NuGet GUI的错误或功能。 (我正在使用Visual Studio 2017的最终发行版)

您可以通过直接编辑.csproj文件来解决该问题:在解决方案资源管理器中右键单击该项目,然后选择Edit(projectname).csproj。

您可以在第一个PropertyGroup中提高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。我用问题中提到的所有(公共)依赖项对此进行了测试,但没有发现任何软件包版本冲突。
