BaseCompositionContextResolver Class

Abstract ICompositionContextResolver that automatically registers any statically defined CompositionContexts found within the class.

Syntax

Visual Basic
C#

'Declaration
 
<PartNotDiscoverableAttribute()>
Public MustInherit Class BaseCompositionContextResolver 
   Implements ICompositionContextResolver

'Usage
 
Dim instance As BaseCompositionContextResolver

[PartNotDiscoverable()]
public abstract class BaseCompositionContextResolver : ICompositionContextResolver

Remarks

If you subclass the BaseCompositionContextResolver and provide static field definitions for your custom CompositionContexts, DevForce will automatically find and register these contexts as needed, and you will not need to implement the GetCompositionContext method. You can still use GetCompositionContext to dynamically construct a CompositionContext for the specified name, but there is no need to do so if all of your composition contexts can be defined statically.

Example

// Sample BaseCompositionContextResolver sub-type providing static fields defining CompositionContexts.
public class CompositionContextResolver : BaseCompositionContextResolver {
 
  public static CompositionContext Mock = new CompositionContext("MyMock", true,
    typeof(MockEntityServerSaveInterceptor), typeof(MockEntityServerQueryInterceptor));
}
 
// Sample class - note it is marked as not discoverable so that standard MEF
// composition will not find it.
[PartNotDiscoverable]
public class MockEntityServerQueryInterceptor : EntityServerQueryInterceptor {

   protected override bool ExecuteQuery() {
      throw new InvalidOperationException();
   }
}
[PartNotDiscoverable]
public class MockEntityServerSaveInterceptor : EntityServerSaveInterceptor {

   protected override bool  ExecuteSave() {
      throw new InvalidOperationException();
   }
}
