This issue actually affects anyone using validators in their applications that went from RC to the final.  With rainbow, thats exactly what we did and a user left a message in the forum that he would get errors trying to install rainbow.  I have found the fix and now rainbow can use the new special Ajax validators until MS releases a system.web patch.  I give credit to Jim Andrew for reporting the issue in our forums.  This just reaffirms our ASP.NET Ajax framework in Rainbow.

The two blog entrees below explain the fix and common issues with ASP.NET Ajax

To fix your beta 1 or ASP.NET Ajax app with this issue :

1.) Go grab the validators from Matt Gibbs  blog above

2.) Add a ref to Validators.dll

3.) Change the tag mappings to the new tag mappings in the pages section of Rainbow's web.config

4.) Recompile and rainbow will load like normal

 

Def by Beta 2 we will have this fixed so you will just install rainbow like normal.  We will also include the installer....

 

Cheers

 

Update:

After I got this issue fixed, I started work on the installer and the Stater kit.  You can view an image of the new Staterkit here.
