原文: 遇到异常:Synchronous operations are disallowed. Call WriteAsync or set AllowSynchronousIO to true instead 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 ; }); } 转自: https://stackoverflow.com/questions/47735133/asp-net-core
