MEF Preview 9 released

MEF Preview 9 was released

MEF preview 9 changes will be reflected the in the release of .NET 4.0 and Silverlight 4.0.

except from bug fixing, there was some changes to the API,

most of the changes is related to  System.ComponentModel.Composition.Initilization.dll,

which is not yet available only for none Silverlight application :-(

here is a short list of API changes:

• PackageCatalog were brought back, and changed it name to DeploymentCatalog.

• PartCreator was renamed to ExportFactory.

• PartInitializer was renamed to CompositionInitializer

• CompositionHost.InitializeContainer was renamed to CompositionHost.Initialize

i do hope that the System.ComponentModel.Composition.Initilization.dll will finally find it place

into the CLR 4.0 release.

you can download it from the MEF codeplex.

UPDATES:

From: Glenn block

Unfortunately we will not be shipping CompositionInitializer / Host as part of .NET 4.0. .NET 4.0 and SL are on different ship cycles and the desktop locked long before we had the functionality in SL. We will do an OOB release on codeplex for desktop. I currently have an early version on my SkyDrive, but we will get bits updated for codeplex. The plan is to role CI into the desktop in the future.
