How do you do object pooling in .NET ?

COM+ reduces overhead by creating object from scratch. So in COM+ when object is activated its activated from pool and when its deactivated it’s pushed back to the pool. Object pooling is configures by using the “ObjectPoolingAttribute” to the class.

Note:- When a class is marked with objectpooling attribute it can not be inherited.

ObjectPooling(MinPoolSize := 2, MaxPoolSize := 5, CreationTimeout := 20000)> _
Public Class testingclass
Inherits ServicedComponent

Public Sub DoWork()

' Method contents go here.

End Sub

End Class

Above is a sample code which has the “ObjectPooling” attribute defined. Below is a sample code which uses the class.

Public Class App

Overloads Public Shared Sub Main(args() As String)

Dim xyz As New TestObjectPooling()
xyz.doWork()

ServicedComponent.DisposeObject (xyz)

End Sub

End Class

Above is a sample code which uses the object pooled object. Note the DisposeObject() This ensures its safe return to the object pool.
