CompositionContainer.ReleaseExport Method

Definition

Namespace:

System.ComponentModel.Composition.Hosting

Assembly:

System.ComponentModel.Composition.dll

Package:

System.ComponentModel.Composition v8.0.0

Overloads

ReleaseExport(Export)	Releases the specified Export object from the CompositionContainer.
ReleaseExport<T>(Lazy<T>)	Removes the specified export from composition and releases its resources if possible.

ReleaseExport(Export)

Source:

CompositionContainer.cs

Releases the specified Export object from the CompositionContainer.

public:
 void ReleaseExport(System::ComponentModel::Composition::Primitives::Export ^ export);

public void ReleaseExport (System.ComponentModel.Composition.Primitives.Export export);

member this.ReleaseExport : System.ComponentModel.Composition.Primitives.Export -> unit

Public Sub ReleaseExport (export As Export)

Parameters

export

Export

The Export that needs to be released.

Exceptions

ArgumentNullException

export is null.

Remarks

The behavior of this method may vary depending on the implementation of the ExportProvider that produced the Export instance. As a rule, non-shared exports should be detached from the container.

For example, the CatalogExportProvider will only release an Export if it comes from a ComposablePart that was constructed under a NonShared context. Release in this context means walking the dependency chain of the Export objects, detaching references from the container and calling Dispose on the ComposablePart objects as needed. If the Export was constructed under a Shared context the CatalogExportProvider will do nothing, as the specified Export may being used by other requestors. Those will only be detached when the container is itself disposed.

ReleaseExport<T>(Lazy<T>)

member this.ReleaseExport : Lazy<'T> -> unit

Public Sub ReleaseExport(Of T) (export As Lazy(Of T))

Type Parameters
