Windows CE. net core OS features (1) -- Application and service development

 

Core OS (core operating system) is the most abundant feature set provided by Windows CE. The features of a customized operating system depend largely on those core OS features selected by developers. These core OS features are not isolated. Some core OS features may need to be supported by other features. When Developers choose some features for their customized operating systems, some of its other features will be automatically added to the developer's custom operating system, and platform builder will automatically parse the relevance between features or components.
In Windows CE. net, core OS is divided into eleven categories based on different features (14 categories in 5.0 ):
Applications and Services Development
Applications-End User
Communication services and networking
Core OS services
File systems and data store
Fonts
International
Internet client services
Multimedia technologies
Security
Shell and user interface

I tried to translate these features and gave some explanations, hoping to help my colleagues. Limited capabilities. Please criticize and point out any mistakes.

-- NET Compact Framework 1.0
. NET Compact framework support,
. NET Compact framework is a subset of. NET Framework. It is designed for devices with small memory sizes .. NET Compact framework is a secure, downloadable application-independent hardware program execution environment. It is positioned on computing devices with limited resources and is specially optimized for these devices.
. NET Compact framework provides a variety of languages to choose from (Microsoft Visual Basic and Microsoft Visual C # were initially available), and eliminates common problems in language interoperability. For example, Visual C # and Visual Basic components can be easily mixed into a solution, so that more developers can easily participate in a solution.
Each language supported by. NET Compact framework can access the underlying framework and operating system features equally .. NET Compact framework also supports Web services. These services allow developers to control the granularity of network transmission on small and short-term connection devices, allow data prefetch in the background and enable applications to collect data from different servers .. NET Compact framework supports all the processors supported by Windows CE. net.
