Solution:


Stop your WAS.
From Add/Remove Projects remove your MDM project.
Publish the server so that it uninstall-ed the application.
During publish also you may get the same error, don't bother about that.


Make sure from admin console MDM is removed.


Stop the server again.
Do a  clean build.
Add/Remove add the MDM project.
Restart/Publish the server.Hopefully it will work. :)
