Hi Adityas,
Can you confirm if you ran the "AppDynamicsics Configuration Tool" and run through the required configurations.
Following link should get you started
http://docs.appdynamics.com/display/PRO13S/Configure+the+App+Agent+for+.NET
In case you have already taken this step can you confirm if you have or had at any point another profiler installed ?
Let me know in case there are any disconnect from my side.
Thanks,
Raunak
