I have a console application which had used Microsoft.Practice.Enterprise Library 
for exception handling and logging etc.
But the dll for the enlib was missing so i installed version 6 from Nuget and built the solution.
When i tried to run/debug the application I get error saying :
ex = "Must set an ExceptionManager in the 
ExceptionPolicy class using the SetExceptionManager method."

Please guide me through how to resolve it. Thank you.

What I have tried:

I have never used entlib. I don't know how it works. I tried to search on internet but could not get the solution.
