The sudden appearance today Could not load file or assembly System.EnterpriseServices this Exception,
Own fiddle for a long time have not been resolved.
Finally found a solution on google.
In the .net version 1.1 directory to get version 2.0 gacutil down
Then execute "GACUTIL / IF System.EnterpriseServices"
