嗯，在使用 asp.net core 中遇到这么一个异常：

Synchronous operations are disallowed. Call WriteAsync or set AllowSynchronousIO to true instead

解决方法，加入配置：

public void ConfigureServices(IServiceCollection services)
{
    // If using Kestrel:
    services.Configure<KestrelServerOptions>(options =>
    {
        options.AllowSynchronousIO = true;
    });

    // If using IIS:
    services.Configure<IISServerOptions>(options =>
    {
        options.AllowSynchronousIO = true;
    });
}
