ThreadPool.QueueUserWorkItem() could be very slow

ThreadPool.QueueUserWorkItem() could be very slow if callback being executed as a work item calls Thread.Sleep(). Consider the following example:

1. using System;
2. using System.Threading;
3.  
4. namespace Test
5. {
6.   class Program
7.   {
8.     const int waitTime = 10000;
9.     static void Main(string[] args)
10.     {
11.       for (int i = 0; i < 10; i++ )
12.         ThreadPool.QueueUserWorkItem( TestProc, i);
13.       Console.ReadKey();
14.     }
15.  
16.     static void TestProc(object stateInfo)
17.     {
18.       Console.WriteLine("Item number #{0} at {1}", (int)stateInfo, DateTime.Now);
19.       Thread.Sleep(waitTime);
20.     }
21.   }
22. }

The problem is that thread pool waits around 500 ms before allocating a new thread.
You may solve it by pre-specifying a minimal amount of threads in your application:
ThreadPool.SetMinThreads(20, 200);

Howto: publish metadata for net.tcp endpoint and add reference to WCF service hosted in process/service/console

app.config => Edit WCF configuration Open "Services" section, then "Endpoints" section. Select an endpoint for which you want to add metadata/MEX endpoint hosted with TCP binding Endpoints => New service endpoint Set Address to something like net.tcp://localhost:5060/MyEndpointMex Set Name to be something like MyEndpointMex Set Binding to mexTcpBinding Set Contract to IMetadataExchange Set ListenUriMode to Explicit Advanced => Service Behaviours => Add "New Service Behaviour Configuration" Add serviceMedatadata section and set both HttpGetEnabled and HttpsGetEnabled to False Now start your service process, open VS 2008, select References and then Add Service Reference. Put net.tcp://localhost:5060/MyEndpointMex in Address field. Enjoy

Metadata contains a reference that cannot be resolved net.tcp

Error "Metadata contains a reference that cannot be resolved: 'service reference'. If the service is defined in the current solution, try building the solution and adding the service reference again." could be caused by specifying specific contract rather than IMetadataExchange in Contract section of service endpoint configuration.

Barrier multithreading primitive in C#

public class Barrier { public Barrier(int count) { Count = count; } public int Count{get; set;} public void Wait() { lock(this) { if (--Count > 0) { System.Threading.Monitor.Wait(this); } else { System.Threading.Monitor.PulseAll(this); } } } }
