VS 2008 Beta 2 and Ajax 1.0 - Workaround

While using the VS 2008 Beta 2 Multitargeting support feature to develope websites targeting the 3.0 framework, I ran into a problem with Ajax 1.0 and the AjaxControlToolkit.  When trying to add a refernce to the AjaxControlToolkit, I got an error message that stated the framework version required by the assembly or one of it's dependencies was higher then the project target framework version.  After some research, I found a blog with a workaround for the problem.  I have posted the link below.  Make sure to read the side affects to the work around before using it.
