    I was trying a small application from book,

    after I run this application, the web page would show as follows:

     You probably are using a Website Project instead a Web Application Project.

    The problem with the first is that every file is compile as a diferent DLL and then they are linked all together. This is done at runtime by the IIS. And sometimes... things go wrong... Sometimes no... Manytimes :P 

     In your error message you have two friendreunion DLL, soo, CS1595: 'FriendReunion.Global' is defined in multiple places...

    c:\windows\microsoft.net\framework\v1.1.4322\temporary asp.net files\friendreunion\2fae48f1\4c99a6c7\assembly\dl2\52518be7\8eed1174_c433c901\friendsreunion.dll
    c:\windows\microsoft.net\framework\v1.1.4322\temporary asp.net files\friendreunion\2fae48f1\4c99a6c7\assembly\dl2\ba55e65f\c3604344_c533c901\friendreunion.dll

     Delete the content of this folder: c:\windows\microsoft.net\framework\v1.1.4322\temporary asp.net files
    You may have to restart the iis or stop the web development server so you can clean the folder.
