Are there other factors I should consider? 回答1: Performance benefits are going to be

问题 I currently use a custom gzip encoder for my WCF service. I want to replace it with the built-in IIS 7 compression if that is possible. I can't find info online on how to that. Is there any way to enable IIS 7 compression for WCF services? Do you know if this will be supported out-of-the-box with .Net 4?

问题 I'm kind of a newbie to Visual Studio programming. I recently upgraded .Net 4.0 to 4.5 in order to use the ZipFile class under System.IO.Compression, but after the installation completed, Visual Studio (I'm using 2012) still cannot recognize ZipFile as a class name.

Could someone help me figure this out? 回答1: See ZipFile Class on MSDN. It shows the required
