in the Windows Phone Store in Windows Phone 8, so typically start and run faster • When you build your app in Visual Studio, the code is not compiled into a native image, but into a machine-independent Common Intermediate Language (CIL) binary file (formerly known as Microsoft Intermediate Language, or MSIL) • When you submit your app to the Windows Phone Store, you submit the CIL file • On submission, CIL file is converted to optimized Machine Dependent Intermediate Language, or MDIL • When a user downloads your app to a device, it is pre-jitted to a native image • Windows Phone 8 Apps Run Faster 4/10/2013 Microsoft confidential 35
