Hi Friends,
This is due to the presence of two versions of Enterprise Library in the system.
Say Enterprise Library 2.0 and 5.0.
One solution is configured to use Enterprise Library 2.0.
But the other is configured to use 5.0.
And hence the properly arises.
If the version is not provided in the Webconfig of any solution, Both would have taken from the GAC and hence it would resolve the problem.
For another solution: please visit..
