    Hi Sergio:  Thanks for the info.  The .NET Agent docs you mentioned talk mostly about how to install/setup/configure... I am looking for info on how it works behind the scene. How does it add hooks to the .NET code? Does it do some type of GAC forwarding? What API does it use to add these hooks? On the Java docs, it's explained clearly that the Java Agent dynamically modifies the Java bytecode. I couldn't find anything that talks about how the .NET Agent does its instrumentation. The only thing I found was something about it getting data from inside the CLR.  Chinh

    That information is in the Overview and Installation guides.

     

    If you read the chapter on manual installation, you will see that the wily.Agent.dll is added to the GAC. The agent works the same way in Java and .NET: bytecode instrumentation is how it's able to inject itself into an application. This is explained in the Overview guide.
