Silverlight 4.0中应用MEF实现组件动态加载的研究

Research and Implementation of Dynamic Assembly of Components Based on MEF in Silverlight 4.0

针对Silverlight生成的xap包文件过大这一问题,提出了按业务逻辑进行分割的策略,并采用MEF技术实现业务功能的按需动态加载,给出具体实现思路与步骤。结果表明,使用MEF能使基于Silverlight的应用系统转换为动态组合、按需下载,进一步增强用户体验。

This paper, aiming at the problem that the file of Xap package, a application system generated by Silverlight, is too large, resulting in a slower download speed, propsoes a business logic partitioning strategy in Silverlight applications, based on open source extensible framework MEF, to realize dynamic load on-demand, and gives concrete thinking line and steps. The results showe that the MEF can make use of Silverlight-based application system into a dynamic combination of on-demand downloads, improve the user application experience, is to create scalable applications for better solutions.
