8�?日消息，据国外媒体报道，微��Y��在8�?3日发布Visual Studio LightSwitch��试版，旨在��化开发应用程序的�q�程。这个Visual Studio集成开发环境非常容易��用，甚至业务�l�理都能使用它开发应用程序�?/p>

微��Y负责开发工具��^台营销的高�U�经理Dave Mendlen��_��专业开发�h员不再是制作业务应用�E�序的唯一人员。LightSwitch��给业务部门的最�l�用��h��供一�U�制作自��q��应用�E�序的简单方法�?/p>

�q�个软�g是一�U�简装版本的Visual Studio开发��^収ͼ�集成了一套模板，包含许多的不同企业流�E�。用户可以��用这些模板制作自��q��应用�E�序�?/p>

Mendlen��_��你可以��用其中的一个模板，使用VB或者C�Q�语�a�向上面添加内宏V��在某些情况下，用户�Ҏ(gu��)��不需要添加代码�?/p>

使用LightSwitch制作的应用程序能够在本地机器上运行或者在微��YAzure云计��服务中�q�行�Q��用配�|�微软Silverlight软�g的浏览器可以讉K��q�种应用�E�序�?/p>

除了模板之外�Q�这个��Y件还提供了一些预制的功能。这个��Y件的用户界面也很独特�Q�开发模式和�q�行时模式没有分开。Mendlen��_��q�就意味着只要用户�q�行一下修改就可以立即在正在运行的�q�个�E�序的测试实例中昄��出来�?/p>

通过市场微��Y�?NET框架�Q�LightSwitch�q�能创徏在办公环境中�q�泛应用的程序�?/p>
