Facing two issues: 
1. Getting the Invalid Archive Type while executing the following code in the local development 
2. Getting Method not resolved for the GetWorklistItems.

As a workaround i updated the dlls from the K2 Five into my application references as a 64 bit and running the solution in debug mode as 64 bit still facing the issue.

Please help me in resolving this issue as i got stuck not able to debug locally.
