我的 Visual Studio 中缺少 .NET Core 2.0 [英] .NET Core 2.0 missing from my Visual Studio

问题描述

所以我已经安装了官方的 .NET Core 2.0 SDK，当我在 Visual Studio 中时，我收到了大量错误并且没有列出目标框架:(

So I've installed the official .NET Core 2.0 SDK and when I'm in Visual Studio i get heaps of errors and the target framework is not listed :(

好像没有安装 .NET Core 2.0.

It's like .NET Core 2.0 isn't installed.

这里是 .csproj 文件:

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

  <PropertyGroup>
    <TargetFramework>netcoreapp2.0</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <Folder Include="wwwroot" />
  </ItemGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore.All" Version="2.0.0" />
  </ItemGroup>

</Project>

此外，dotnet --version 返回 2.0.0

所以.. 有没有我遗漏的安装工具?

so .. is there some install tooling I'm missing?

这是我来自 VS 的系统信息:

Here's my system info from VS:

推荐答案

啊！

我的解决方案的根目录中有以下 global.json:

I had the following global.json in the root of my solution:

{
  "projects": [ "src", "tests" ],
  "sdk": {
    "version": "1.0.4"
  }
}

所以我不得不将版本从 1.0.4 更改为 2.0.0 然后关闭/重新打开解决方案.

So I had to change the version from 1.0.4 to 2.0.0 and then close/re-open the solution.

问题解决了:)
