使用新的 .NET Core 2.2 Web API 获取 SDK 错误

Question

我正在Visual Studio中创建一个新的Web API项目。 我使用了Visual Studio ASP.NET Core Web App->Web Api项目模板：

Severity    Code    Description Project File    Line    Suppression State
Error   NETSDK1045  The current .NET SDK does not support targeting .NET Core 2.2.  
Either target .NET Core 2.1 or lower, or use a version of the .NET SDK that supports .NET Core 2.2. CMS.Api

解决方案资源管理器中显示 NuGet 依赖项 Microsoft.AspNetCore.Razor.Design (2.2.0(。

环境：

我看了以下内容：https://dotnetcoretutorials.com/2018/11/18/how-to-target-net-core-2-2/

内容管理系统。Api.csproj

<Project Sdk="Microsoft.NET.Sdk.Web">
  <PropertyGroup>
    <TargetFramework>netcoreapp2.2</TargetFramework>
    <AspNetCoreHostingModel>InProcess</AspNetCoreHostingModel>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore.App" />
    <PackageReference Include="Microsoft.AspNetCore.Razor.Design" Version="2.2.0" PrivateAssets="All" />
  </ItemGroup>
</Project>

我在项目文件夹的根目录中创建了一个 global.json：

{
  "sdk": {
    "version": "2.2.203"
  }
}

但是每当我尝试执行NuGet包还原时，都会收到相同的错误。

有什么想法吗？

请检查，

1. 已安装".NET Core 2.2"SDK x64 或 x86 版本。如果没有，您可以从 https://dotnet.microsoft.com/download/visual-studio-sdks 下载
2. 确保在以下文件夹结构下生成"2.2.110"文件夹。
