Please also keep in mind that the whitepaper that comes with the CSS Friendly adapter kit contains a section entitled, "Using these adapters in your web site" that is intended to give you a step-by-step set of instructions for using these adapters in an existing web site, http://www.asp.net/cssadapters/whitepaper.aspx#SamplesUsingInYourWebSite. That section's intro includes this statement, "If you want to integrate these adapters into an existing site, follow these instructions..."

The CodePlex solution is probably easier for most people to use, however, as it involves far fewer files. However, there are many cases where folks can't use a DLL in their site due to security limitations. In such cases it is best to use the kit's uncompiled files in order to integrate these adapters. Either way, it shouldn't be terribly hard to do this integration.
