.NET Micro Framework 4.0 features:
· HTTP and HTTPs: An object model is now provided for handing both HTTP clients and servers, similar to the .NET Framework, with the new types System.Net.HttpWebRequest, System.Net.HttpWebResponse, and System.Net.HttpListener from assembly System.Http.dll
· Multi-touch: Basic support for multi-touch events, such as moving two fingers on a touch screen, is now provided in the object model and the emulator. Gesture support has been redesigned to be faster and more flexible.
· Versioning: Versioning has been implemented to strictly identify assemblies by the version number at build time and on the device, and eventually re-deploying missing assemblies. Side-by-side load and bind for types belonging to the same assemblies with a different version number is supported. Support has also been added for assembly naming which includes the version number.
· Emulator support for SSL and HTTPS: The emulator now explicitly supports SSL and HTTPs emulation.
· Native XML Parser: The XML parser has been moved to native code for better performance.
· Native collections: The collection classes have been moved to native code for performance, and have been enriched with Queue and Stack types.
· Time sync: Devices can use the new Time Sync API to sync the system time with a specified server's time, automatically or manually.
· Arbitrary display size: A custom heap and allocation area is now provided to support bitmaps larger than 760KB.
· Large buffers: A new type, Microsoft.SPOT.Hardware.LargeBuffer, is provided for allocating buffers larger than 760KB, which would not fit in the managed heap. This type is located in assembly Microsoft.SPOT.Hardware.
· Watchdog and Power Level control: The power level and the watchdog behavior can now be controlled from the managed application using types Microsoft.SPOT.Hardware.PowerState and Microsoft.SPOT.Hardware.Watchdog from assembly Microsoft.SPOT.Hardware.dll.
· Thick pens and gradient fills: A richer graphic model is now provided for designing widgets and controls.
· TinyCore performance improvements: TinyCore performance has been enhanced in the area of event dispatching and layout.
