GLIBCXX

经实践，编译为 NativeAOT 后可直接运行，无视 GLIBCXX 版本低的问题

CentOS 7 默认的版本较低，需要升级 libstdc++6

/lib64/libstdc++.so.6: version GLIBCXX_3.4.20 not found
/lib64/libstdc++.so.6: version GLIBCXX_3.4.21 not found

搜索已有版本，CentOS 7.6.1810 搜索出来最高版本为 GLIBCXX_3.4.19

strings /usr/lib64/libstdc++.so.6 | grep GLIBCXX

替换 CentOS7 so 文件

# 下载 lib64 并解压
wget https://adbin.top/packages/lib64.tar.gz
tar -xzf lib64.tar.gz

# 替 /usr/lib64/libstdc++.so.6
cd /lib64
cp libstdc++.so.6.0.25 cd /usr/lib64

# 重新 link
cd /usr/lib64
rm libstdc++.so.6
ln -s libstdc++.so.6.0.25 libstdc++.so.6

System.Text.Json 组件得使用源生成 source generation

public class WeatherForecast
{
    public DateTime Date { get; set; }
    public int TemperatureCelsius { get; set; }
    public string Summary { get; set; }
}

[JsonSerializable(typeof(WeatherForecast))]
internal partial class SourceGenerationContext : JsonSerializerContext
{
}

/// <summary>
/// 转为 JSON  （this 就是实体对象）
/// </summary>
/// <returns></returns>
public string ToJSON() => JsonSerializer.Serialize(this, SourceGenerationContext.Default.WeatherForecast);
