Unable to create Microsoft Enterprise library instance
we had a requirement where we had to update the version of Microsoft Enterprise library from v.1.6.0.0 to v.2.0.0.0,
Biztalk server connects to the database using the connection string and other parameters configured in the configuration file, whose location is provided in the machine.config.
we had made the required changes by changing the assembly name and databases if any.
restarted the host instance, even then the problem persisted.
problem : unable to connect to database.
diagnose: we did run the batch files which installs the services on the machine along with the GACing of all the assemblies with the updated version 2.0.0.0.
we just gaced manually one by one which was required , i.e if we required Microsoft.Enterprise.library.Data, we only added this to the GAC.
Resolution: run the batch file and then copy all the assemblies to gac, restart host instance. and you are done.
