setup工程中安装net运行时

目前知道2中方法。一个是用CustomAction的方式执行Exe,使用这种方式不仅仅可以安装net framework，而且还可以执行任何Exe程序。另一个是使用setup工程属性中的Prerequisites功能。

A. Custom Action 

1. 取得net分发包，可以在microsoft的网站上下载，是一个exe文件

2.  在file system中加入这个Exe文件 

3.  进入custome action.  执行Add custome Action, 选择这个Exe.

4.  在Custome Action中选中刚刚加入的文件，按F4,编辑属性。 Installer Class设置为false ;Arguments设置为命令行参数 
   

 Note: 命令行参数可以google到，下面是.net 3.0的命令行:

B. Prerequisites

注意： 上面的文章在处理.net framework 3.5 sp1时有点问题，会编译不过。

解决方法：

1. Navigate to the following URL: http://go.microsoft.com/fwlink?LinkID=118080
2. Download the dotNetFx35.exe file to your local disk.
3. Open a Command Prompt window and change to the directory to which you downloaded dotNetFx35.exe.
4. At the command prompt, type:
   dotNetFx35.exe /x:.
   This will extract the Framework files to a folder named “WCU” in the current directory.
5. Copy the contents of the WCU\dotNetFramework folder and paste them in the %Program Files%\Microsoft SDKs\Windows\v6.0A\Bootstrapper\Packages\DotNetFx35SP1 folder (%ProgramFiles(x86)%\Microsoft SDKs\Windows\v6.0A\Bootstrapper\Packages\DotNetFx35SP1 on x64 operating systems). Note: Do not copy the WCU\dotNetFramework folder itself. There should be 5 folders under the WCU folder, and each of these should now appear in the DotNetFx35SP1 folder. The folder structure should resemble the following:
   o DotNetFx35SP1 (folder)
   • dotNetFX20 (folder
   • dotNetFX30 (folder)
   • dotNetFX35 (folder)
   • dotNetMSP (folder)
   • TOOLS folder)
   • en (or some other localized folder)
   • dotNetFx35setup.exe (file)

You may now delete the files and folders you downloaded and extracted in steps 2 and 4.
