This new implementation, now available for download in the Expression Gallery, permits to enable Multi-Touch gestures (the usual translation, rotation, zoom and inertia) on separate User Controls available in the same container.

In this way you can apply distinct Multi-Touch manipulations (inertia included) to single elements using a single code in xaml.

Today I’ve finally found some time to make modifications in the “MEF MVVM” project on Codeplex in order to:

• create a new module using WCF RIA Services and dynamically load this it inside the “MEF module container” described in the previous post;
• use the INavigationContentLoader interface and MEF Metadata to share the same container for the various “MEF Modules”;
• use the new Cosmopolitan theme available for Silverlight Navigation applications [...]

I’ve already blogged about adding multi-touch support to Silverlight applications using Blend behaviors (you can also read my italian language article).

This is a powerful and simple approach which is now available in WPF using Expression Blend 4 RC and the TranslateZoomRotateBehavior.

The samples contain the following topics:

• Simple composition using the CompositionInitializer;
• Multiple Exports;
• Metadata;
• Custom Attributes;
• Dynamic object creation with ExportFactory [...]

The Microsoft Surface Toolkit for Windows Touch Beta is a set of controls, APIs, templates, sample applications and documentation currently available for Surface developers.

With the .NET Framework 4.0, Windows Presentation Framework 4.0 (WPF), and this toolkit, Windows Touch developers can quickly and consistently create advanced multitouch applications for Windows Touch PCs.

I think that inserting multi-touch manipulation effects to a Silverlight application using Blend behaviors is an elegant way which makes the code very clear and readable.
