vs code 问题：preLaunchTask“build”已终止,退出代码为 1。解决办法

菜单：任务-配置任务

改为如下：
{
    // See https://go.microsoft.com/fwlink/?LinkId=733558
    // for the documentation about the tasks.json format
    "version": "2.0.0",
    "command": "",
    "args": [],
    "tasks": [
        {
            "label": "build",
            "command": "dotnet",
            "type": "shell",
            "args": [
                "build"
            ],
            "options": {
                "cwd": "${workspaceRoot}"
            },
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "presentation": {
                "echo": true,
                "reveal": "always",
                "focus": false,
                "panel": "shared"
            },
            "problemMatcher": "$msCompile"
        }
    ]
}
