WebResource.axd throwing error "Parameter count mismatch"

[William Hurst]

We are suddenly receiving the error detailed below but I am unable to determine the cause. The Telerik assembly is from 2011 so it is a few years old.

Exception Details: System.Reflection.TargetParameterCountException: Parameter count mismatch.

Stack Trace: 
[TargetParameterCountException: Parameter count mismatch.]
