ArgumentOutOfRangeException decompiling System.Web.Mvc.dll

[RJ Cuthbertson]

In the most recent build of JustDecompile, I encountered the following exception while trying to navigate through source code by clicking on the method call to jump to the method's definition. Specifically, this occurred in the AreaRegistration class in System.Web.Mvc when clicking on a reference to the abstract method "public abstract void RegisterArea(AreaRegistrationContext context)". The exception caused JustDecompile to crash and was not immediately reproducible.

 

System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.
