Error while Migrating to PB 12.6 Net version from 11.5 Classic Version

Hello All,

We are trying to migrate our application and we are able to migrate successfully to PB 12.6 classic version.

But, we are getting some error when we tried to migrate to PB 12.6 .net version and below is the error.

---------------------------

PBL Already Loaded

---------------------------

The PBL has already been loaded in a different target.  PowerBuilder does not support using the same PBL in different targets within the same solution.

Please remove or replace one of these PBLs and reload the solution.

---------------------------

OK  

---------------------------

Thanks in advance.
