无法使用VS Code

问题描述

我有Windows 7 64位计算机。以下是dotnet --info

的输出

.NET Core SDK (reflecting any global.json):
 Version:   3.0.100

以下是我的csproj文件

<Project Sdk="Microsoft.NET.Sdk.Web">
  <PropertyGroup>
    <TargetFramework>netcoreapp3.0</TargetFramework>
    <RuntimeIdentifiers>linux-x64</RuntimeIdentifiers>
  </PropertyGroup>
</Project>

当我尝试运行dotnet build -r linux-x64时，出现以下错误

Microsoft (R) Build Engine version 16.3.0+0f4c62fea for .NET Core

我想我没有在Windows机器上安装运行时。但是我不确定如何在Windows计算机上为Linux添加运行时。我找不到任何文档。 我最终希望将其部署在Linux机器上。

解决方法

我认为那是因为您没有使用Windows路径

,

问题是因为VS代码不会自动从nuget.org中提取。

创建Nuget.config文件并添加nuget.org软件包源已修复该文件。

<?xml version="1.0" encoding="utf-8"?>
<configuration>
<packageSources>
    <add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
</packageSources>
</configuration>
