利用 transform Configuration, 用来解决不同环境(如开发、生产环境)使用不同配置的情况, 只需切换Debug、Release或其它自定义配置, 最终生成相应的配置文件.

目录结构:

| App_Config
|   Web.Base.config
|   Web.Debug.config
|   Web.Release.config

Visual Studio 如何将 WIN32 dll 复制到输出目录?

打开项目属性，选择“Build Events”，在“编译前事件命令行”文本框中输入以下命令(假设外部dll放在项目根目录下的 ExternalDlls 目录下):

xcopy /y /d "$(ProjectDir)ExternalDlls\*.dll" "$(ProjectDir)$(OutDir)"

参数说明：

$(ProjectDir) : 项目所在目录
$(OutDir) : 编译后输出目录
