"Add Service Reference" 16384 quota

If you got a problem with adding large WCF service into your Visual Studio sollution via "Add Service Reference" you can use following sollution.

You need to edit devenv.exe.config (default located in c:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\) and add larger quota info to IMetadataExchange binding. This configuration will be used by VS and it is used for netTcpBinding.

<configuration>
.
.
.
<system.serviceModel>
<client>
<endpoint name="net.tcp" binding="netTcpBinding" bindingConfiguration="bc" contract="IMetadataExchange" />
</client>
<bindings>
<netTcpBinding>
<binding name="bc" maxReceivedMessageSize="512000">
<readerQuotas maxNameTableCharCount="163840" />
<security mode="None"/>
</binding>
</netTcpBinding>
</bindings>
</system.serviceModel>
.

</configuration>

Finding objects in Generics with List.Find()

Simple class:

public class Person
{
   public int ID { get; set; }
   public int Name { get; set; }

   public Person(int id, string name)
   {
      ID = id;
      Name = name;
   }
}

Usage code:

//Add some objects
List myList = new List();
myList.Add(new Person(1, "Person 1"));
myList.Add(new Person(2, "Person 2"));
myList.Add(new Person(3, "Person 3"));

//Find a specific object
Person myLocatedObject = myList.Find(delegate(Person p) {return p.ID == 1; });
