New Class and Hidden Gotcha! for .NET 3.5 Service Pack 1
If you are researching this class because you received the following exception: 

Could not load type 'System.Web.UI.ScriptReferenceBase' from assembly 'System.Web.Extensions, Version=3.5.0.0, 
Culture=neutral, PublicKeyToken=31bf3856ad364e35'.

It's highly likely that you compiled your code using .NET 3.5 Service Pack 1 but deployed to a system that has .NET 3.5 without Service Pack 1.

ScriptReferenceBase is a new class for Service Pack 1, clearly a refactoring of ScriptReference to allow common code for the new CompositeScriptReference class. If you compile your code using SP1, you will include a reference to this class, which does not exist in .NET 3.5 pre-SP1. When the non-SP1 runtime tries to load the class, you will receive the exception above.

Solutions are:

  • Compile using .NET 3.5 without SP1.
    --OR--
  • Install SP1 on the target system
