      <para>The DynamicObject class enables you to define which operations can be performed on dynamic objects and how to perform those operations. For example, you can define what happens when you try to get or set an object property, call a method, or perform standard mathematical operations such as addition and multiplication.</para>
      <para>This class can be useful if you want to create a more convenient protocol for a library. For example, if users of your library have to use syntax like Scriptobj.SetProperty("Count", 1), you can provide the ability to use much simpler syntax, like scriptobj.Count = 1.</para>
      <para>You cannot directly create an instance of the DynamicObject class. To implement the dynamic behavior, you may want to inherit from the DynamicObject class and override necessary methods. For example, if you need only operations for setting and getting properties, you can override just the <see cref="M:System.Dynamic.DynamicObject.TrySetMember(System.Dynamic.SetMemberBinder,System.Object)" /> and <see cref="M:System.Dynamic.DynamicObject.TryGetMember(System.Dynamic.GetMemberBinder,System.Object@)" /> methods.</para>
      <para>In C#, to enable dynamic behavior for instances of classes derived from the DynamicObject class, you must use the dynamic keyword. For more information, see <format type="text/html"><a href="3828989d-c967-4a51-b948-857ebc8fdf26">Using Type Dynamic (C# Programming Guide)</a></format>.</para>
      <para>In Visual Basic, dynamic operations are supported by late binding. For more information, see <format type="text/html"><a href="d6ff7f1e-b94f-4205-ab8d-5cfa91758724">Early and Late Binding</a></format>.</para>
      <para>The following code example demonstrates how to create an instance of a class that is derived from the DynamicObject class.</para>
      <code>public class SampleDynamicObject : DynamicObject {}
//...
dynamic sampleObject = new SampleDynamicObject ();</code>
      <code>Public Class SampleDynamicObject 
    Inherits DynamicObject
'...
Dim sampleObject As Object = New SampleDynamicObject()</code>
      <para>You can also add your own members to classes derived from the DynamicObject class. If your class defines properties and also overrides the <see cref="M:System.Dynamic.DynamicObject.TrySetMember(System.Dynamic.SetMemberBinder,System.Object)" /> method, the dynamic language runtime (DLR) first uses the language binder to look for a static definition of a property in the class. If there is no such property, the DLR calls the <see cref="M:System.Dynamic.DynamicObject.TrySetMember(System.Dynamic.SetMemberBinder,System.Object)" /> method.</para>
      <para>The DynamicObject class implements the DLR interface <see cref="T:System.Dynamic.IDynamicMetaObjectProvider" />, which enables you to share instances of the DynamicObject class between languages that support the DLR interoperability model. For example, you can create an instance of the DynamicObject class in C# and then pass it to an IronPython function. For more information, see <format type="text/html"><a href="f769a271-8aff-4bea-bfab-6160217ce23d">Dynamic Language Runtime Overview</a></format> and documentation on the <see cref="http://go.microsoft.com/fwlink/?LinkId=141028">CodePlex</see> Web site.</para>
      <block subset="none" type="note">
        <para>If you have a simple scenario in which you need an object that can only add and remove members at run time but that does not need to define specific operations and does not have static members, use the <see cref="T:System.Dynamic.ExpandoObject" /> class.</para>
        <para>If you have a more advanced scenario in which you need to define how dynamic objects participate in the interoperability protocol, or you need to manage DLR fast dynamic dispatch caching, create your own implementation of the <see cref="T:System.Dynamic.IDynamicMetaObjectProvider" /> interface.</para>

          <para>Classes derived from the <see cref="T:System.Dynamic.DynamicObject" /> class can override this method to specify how operations that set a value to a member should be performed for a dynamic object. When the method is not overridden, the run-time binder of the language determines the behavior. (In most cases, a language-specific run-time exception is thrown.)</para>
          <para>This method is called when you have statements like sampleObject.SampleProperty = "Test", where sampleObject is an instance of the class that is derived from the <see cref="T:System.Dynamic.DynamicObject" /> class.</para>
          <para>You can also add your own members to classes derived from the DynamicObject class. If your class defines properties and also overrides the <see cref="M:System.Dynamic.DynamicObject.TrySetMember(System.Dynamic.SetMemberBinder,System.Object)" /> method, the dynamic language runtime (DLR) first uses the language binder to look for a static definition of a property in the class. If there is no such property, the DLR calls the <see cref="M:System.Dynamic.DynamicObject.TrySetMember(System.Dynamic.SetMemberBinder,System.Object)" /> method.</para>
