This evening my friend and colleague Jan Tielens released a new version of the SmartPart. For the few who do not know what I'm talking about, the SmartPart allows you to create SharePoint 2007 Web Parts using Web User Controls ( .ascx ) created with the Visual Studio designer.
This version of the SmartPart allows you to install it using a wizard, which makes live much more easy J. There is also support for localization using ASP.NET Ajax controls and User Control samples are added to make you more productive using the SmartPart.
So go and download it from the codeplex community site.
