For those of you that have not seen the Version 2.0 of the Updater Application Block has been released. Check it out here.
The Updater block is one of my favorite pieces of of the Enterprise Library. If you are have not heard about the Updater block it enables your .NET Windows Forms projects to automatically poll a central server. When an update is posted on that server the Updater block the user is prompt in the application if they would like to update. If the answer is yes the files are downloaded on a background thread. When the download is complete the user is prompted to restart the application when they are ready.
The 2.0 Updater block provides a nice transition to the coming ClickOnce deployment model of Whidbey. If you are running Windows Forms/Smart Client application with VB.NET I strongly suggest you take a look.
