Question

.NET Obfuscation error?

Hi,

I have run across a problem using a 3rd party .NET assembly in ColdFusion. I believe that it is because it is obfuscated, but I have never used CF before so I'm hoping someone has seen a similar error.  I am just running a simple test to load the assembly and then use cfdump to see that is has loaded. The browser just displays a blank page but has the exception below in the installation\logs directory. In the example I use a test dll, TempLib.dll, which is just a simple class that inherits from a class in liquidXML. If I run a test that just loads the liquidxml dll and dump it then it works just fine.

Thanks for any help,

Bruce
