I found some problems when I try to deploy my ASP.NET website into wwwroot directory of IIS7 service. It isn't work. The characteristic of my website is include 3 projects together. one is a website, one is a business logic layer project and the last is data layer project. Two project wrote with C# and needs to compile to be Dynamic Link Library (DLL) file that needs to use in a website project. However, when I try to deploy, the code get fatal error with message that it cannot find the link reference such as com.swdev package which I import to ASP.NET code. I cannot find the good keywords that should be use to googling the solution for me. This is my step

1. Zip website folder on development machine
2. extract to folder inside wwwroot
3. start IIS7 service, Ms SQL Express
4. Open IE7 with http://localhost/deploydirectory/
