解决： 未找到ExecutionContext.cs

System.InvalidOperationException:“Sequence contains more than one matching element”

我在使用asp.net core 2.0 , 使用 httpServer 中。报错。如下图。

var route_config = new List<Route>() {

new Route { Name = "API_Assembly_Execution", UrlRegex = @"^/AssemblyExecution/AddAssemblyExecution", Method = "POST", Callable = new API.API_Assembly_Execution().Handle, },

new Route { Name = "API_Assembly_AddFinishedAssembly", UrlRegex = @"^/AssemblyExecution/AddAssembly", Method = "POST", Callable = new API.API_Assembly_AddFinishedAssembly().Handle, }, }; int port = 1122， httpServer = new HttpServer(port, route_config); Thread thread = new Thread(new ThreadStart(httpServer.Listen)); thread.Start();

经发现，这个前半部分一样，冲突了。

解决办法：

将后面的名称改一下：

new Route { Name = "API_Assembly_AddFinishedAssembly", UrlRegex = @"^/AssemblyExecution/SaveAssembly", Method = "POST", Callable = new API.API_Assembly_AddFinishedAssembly().Handle, },

即测试成功！
